FRM are notorious for failures.
A common cause is trying to read / write them with low battery charge.
The usual failure mode is a corruption of the code…probably yours has a checksum error which it’s flagged when you’ve tried to read it.
Normally the only fix is to send it to someone who can re-program the software.
Since it’s connected to so many other things errors can be created by other devices failing …but it doesn’t sound in this case that that’s the cause.

Introduction
The footwell module (FRM) is an electrical nodal point in the footwell on the drivers side. The footwell module picks up the signals from the doors and controls the lighting. The footwell module also controls the adaptive headlights. The footwell module is also the interface to the dashboard. [System overview ...]
Note: System description for the adaptive headlight
There is a separate system description for the adaptive headlights.
[For further information, please refer to BMW Service Technology (SBT) 63 02 03 007]
Brief component description
The following components deliver signals for the footwell module:
Height sensors
Reversing light switch
Brake light switch
Hazard warning flasher switch
Light switch
Driver's door switch block
Door contacts in rear doors
Door contacts in front doors
Driver's door lock
A number of control units are involved in the lighting system. In a stricter sense, the following control units are involved in the lighting (in alphabetical order):
ACSM or MRS: Crash safety module / multiple restraint system
> E81, E82, E87, E89, E90, E91, E92: multiple restraint system
> E70, E71, E93: ACSM stands for ”Advanced Crash Safety Module”, also known as the Crash Safety Module
The footwell module is connected to the crash safety module / MRS control unit via the K‐CAN. In the event of an accident with corresponding severity, the footwell module switches on the interior light and the hazard warning lights automatically.
> E92
The crash safety module sends a message regarding the front passenger seat occupation detection on the K CAN.
The belt handover on the passengers side is only activated when the front passenger seat is occupied.
AHM: Trailer module
The trailer module delivers the signal indicating whether a trailer is attached to the vehicle. The trailer module also controls the trailer lighting. During trailer towing, the trailer module automatically disables e.g. the rear Park Distance Control (PDC) and the rear fog lamp on the vehicle.
If a trailer is detected, the automatic parking function is disabled. Automatic parking function: To improve the view of the kerb, the outside mirror glass is folded downwards when reverse gear is engaged. This brings the lower area immediately around the vehicle, i.e. the kerb, into the field of vision.
The trailer module (AHM) is connected to the footwell module via the K‐CAN.
DSC: Dynamic Stability Control
When cruise control is in operation, the brake lights are actuated during automatic braking (legal requirement). To do this, a signal must be sent from the DSC to the accelerator pedal module via the PT‐CAN.
FLA: High-beam assistant
In accordance with the traffic situation, the high-beam assistant sends a switch-on recommendation or a switch-off recommendation for the high-beam headlights to the footwell module (FRM). On the basis of this recommendation and various other the input variables, the footwell module decides whether the main-beam headlights should be switched on or off.
[for more information, please refer to SI Technology (SBT) 63 01 05 140]
FRM: Footwell module
The footwell module is connected to the vehicle with 3 plug connections. Two 51‐pin connector connect the main wiring harness. Another 26‐pin connector is for the connection to the dashboard. [more ...]
FZD: Roof function centre
The roof function centre is responsible for the components of the interior lighting in the roof area. The Basic variant of the roof function centre has its own control unit. The interior light and the rear-compartment interior light are activated via the footwell module (FRM).
The High variant of the roof function centre has its own control unit, the FZD control unit.
The footwell module is connected to the FZD control unit via the K‐CAN.
[for more information, please refer to SI Technology (SBT) 61 02 04 091]
JBE: Junction Box Electronics
The lighting for the luggage compartment and the glove box lighting are connected to the junction box electronics.
[for further information, please refer to BMW Service Technology (SBT) 61 05 04 095]
LDM: Longitudinal dynamics management
In conjunction with the LDM, the option ”Active Cruise Control” uses the ”turn signal” from the footwell module to help when changing lanes. In other words, if a left turn indicator is given before overtaking, the distance to the vehicle in front is reduced. The vehicle to be overtaken is then ”lost” more quickly. On the other hand, when changing to the right-hand driving lane, a vehicle moving there is picked up more quickly.
[for more information, please refer to SI Technology (SBT) 66 03 04 086]
RLS / RLSS: Rain/light sensor or rain/light solar sensor
> E81, E82, E87, E89, E90, E91, E92, E93: Rain/light sensor
> E70, E71: rain/light solar sensor
The rain/light sensor measures the ambient brightness outside the vehicle.
Depending on the ambient lighting conditions, the footwell module will switch the driving lights on or off. To do this, the automatic driving lights control must be activated (light switch in switch position ”A”).
At dusk, the rain-light sensor sends the message ”dusk”. The footwell module switches the low-beam headlight on. The automatic headlight-range adjustment for the dipped-beam headlights is actuated.
In darkness, the rain/light sensor transmits the message ”Darkness”. The adaptive headlights are then activated when the vehicle is cornering.
SZL: Steering column switch cluster
The switch signals from the turn-signal/high-beam switch are picked up and evaluated by the SZL. The evaluated switch signals are forwarded as resistance-coded by the SZL via direct lines to the footwell module
[for more information, please refer to SI Technology (SBT) 61 07 04 103]
The following components are controlled:
Exterior mirrors
Power window drive
Headlight
Tail lights
Fog lights
Centre high-mount stop lamp
Auxiliary turn indicator light
Front courtesy lighting
Rear courtesy lighting
Number-plate light
2 stepper motor controllers for the adaptive headlight stepper motors
2 belt feeder controllers (only E92)
Seatbelt extender controller (only E92)
The footwell module (FRM) activates the two belt hand-over controllers for the drivers and passengers side. The belt hand-over controllers are connected across an LIN bus on the footwell module.
The belt hand-over controller activates the drive of the belt hand-over.
The position of the drive is reported back to the belt feeder controller by a Hall sensor in the drive.
The end position of the extended belt feeder is recorded by another Hall sensor. The end position is indicated to the belt feeder controller.
The belt feeder controller transmits both signals to the footwell module (FRM) via the LIN bus. The actuation circuit is located in the footwell module.
The belt handover on the passengers side is only activated when the front passenger seat is occupied.
System functions
The following functions are executed by the footwell module:
Gateway between LIN bus and K‐CAN
Waking by means of various signals
Storing vehicle order
Other functions
Gateway between LIN bus and K‐CAN
The footwell module (FRM) enables communication to take place between the LIN bus and the K‐CAN.
The footwell module transfers the messages to the relevant recipient bus.
Components on the LIN bus:
Special equipment exterior mirrors
Switch block in driver's door, High variant
2 stepper motor controllers for the adaptive headlight stepper motors
2 belt feeder controllers (only E92)
Waking by means of various signals
The footwell module (FRM) can be wakened via the following signals:
K-CAN active
Terminal 15 ON
Hazard-warning switch ON
Change in status of door contacts
Anti-theft alarm system triggered
Storing vehicle order
The vehicle order is stored in the footwell module (FRM). For the order to be stored, terminal 15 must be ON and the vehicle must be travelling at a road speed of less than 5 km/h.
The vehicle order enables the vehicle to be identified. Besides the type code number, the vehicle order contains all important equipment features on the vehicle.
Other functions
The footwell module (FRM) influences various functions in the vehicle. The following components are controlled by the footwell module:
Exterior mirrors
Exterior lighting
Interior lighting
Central locking system
Power window regulator
Exterior mirrors
There are 2 versions of the switch block in the driver's door:
Switch block in the driver's door, basic variant
The switch block sends its signals directly to the footwell module (FRM).
Switch block in driver's door, High variant
The switch block is connected to the LIN bus. The requests to adjust the mirror are sent via the LIN bus. The footwell module (FRM) receives and processes the signals via the LIN bus. Every 20 milliseconds, the footwell module queries whether there are requests from the switch block. In the Sleep mode, the power supply is switched off. The outside mirrors cannot be actuated. The mirror heating is controlled by the footwell module. The corresponding information is forwarded to the evaluation electronics in the mirror via the LIN bus.
If a mirror memory is installed, the footwell module saves the memory position of the mirrors. [more ...]
Exterior lights
The lighting function are integrated in the footwell module (FRM). These lighting function are:
Parking lamps
High-beam headlight
Headlamp flasher
Turn indicator
Hazard warning flashers
Brake light
Low-beam headlights
Reversing lights
Fog lights
Rear fog light
Parking lamps
Besides the lighting functions, other exterior lighting functions are also integrated in the footwell module:
Lighting system monitoring
Headlamp range control
Emergency operating mode if the footwell module fails
Lamp replacement
(important lighting functions are substituted by other lights being actuated in the event of individual lights failing.)
"Follow-me-home" lighting
Visual alarm after anti-theft alarm has been triggered
(the visual alarm is given as per encoding with hazard warning lights, turn signals with dipped headlights or turn signals with main-beam headlights.)
Actuation of bi-xenon headlamps
Activation of the step motor controller for the adaptive headlights
Cornering light
The cornering light is coupled to the Adaptive Headlight.
All lighting functions except the additional brake light are supplied with a pulse-modulated signal by the footwell module (FRM). This PWM signal enables a uniform brightness of the exterior lights.
Interior lights
On vehicles without roof function centre (FZD), the footwell module actuates the interior lighting in the roof area directly.
All footwell module outputs for interior lighting are pulse-width modulated. This ensures that the interior lighting maintains constant brightness despite voltage fluctuations.
With standard equipment, the interior lighting comprises the following components:
Front interior light
Luggage compartment lights
Glove compartment lighting
Footwell lighting
The following components can also be installed as special equipment for the interior lights:
Rear interior light
Ground lights
Central locking system
The footwell module evaluates the status of the Hall effect sensors in the door contacts.
When the vehicle is locked or unlocked with the mechanical key element, the footwell module will recognise this request. The footwell module transmits a message on the K‐CAN to the CAS (Comfort Access System):
[for more information, please refer to SI Technology (SBT) 61 01 04 072]
Power window regulator
The footwell module (FRM) and the junction box electronics (JBE) control the power window drives.
The relays for the front power windows motors are located in the footwell module. The relays for the rear power window drives are fitted in the junction box electronics.
[more ...]
Switch-on conditions
The footwell module (FRM) receives a large number of input signals that switch on the interior lighting. The input signals are directly read into the footwell module or are received via the K‐CAN.
The following signals switch the interior lighting ON:
Interior lighting button pressed
Door opened
Unlocking the driver's door with the door lock
Unlocking using remote control
Terminal R OFF, if terminal 58g was ON no more than 2 minutes earlier
Crash signal present
Lock button on remote control pressed when central locking system has been in central double-locking for at least 10 seconds
The interior lighting is switched off under the following preconditions:
Central locking system set to thiefproof mode, all doors and the tailgate closed
Interior lighting button pressed for longer than 3 seconds
Terminal 58g ON and terminal R OFF
Terminal R ON with doors closed
The vehicle is unlocked with the remote control and no door is opened with the space of 20 seconds
Terminal R OFF and a car door left open for longer than 1 minute
Via diagnosis ”Power Down”
8 minutes after terminal R OFF
When terminal R is switched OFF, the footwell module (FRM) will switch the interior lighting off after 8 minutes. To do so, the footwell module sends the message for consumer shutdown via the K CAN. The roof control panel (FZD) receives this message and switches off the interior lighting in the roof area. Interior lights that are switched on directly by the footwell module are also switched off.
The footwell module provides terminal 58g via the K CAN or via conventional wiring. Terminal 58g is pulse-width modulated and has 2 brightness stages.
Brightness level for locating lights
The brightness for the locating lights can be set individually with the rocker switch on the steering-column stalk.
Brightness level for function lighting
The brightness level for function indicator light is not dimmed and is switched on at full intensity.
As soon as the hazard warning switchhas been pressed, the lighting of the hazard warning switch is switched to full brightness by the footwell module. The hazard warning switch is not illuminated at maximum brightness when Terminal 58g is active. The brightness depends on the setting for the locator lighting.

The gold plated version is:
Ensure battery is fully charged or put on external charger
Plug obd reader into port but do not use
Ensure seat belt buckled, doors closed..do not activate windows, switch radio / ac off (unless part of de-bug)
Insert key
Press starter without foot on brake..engine warning light on
Proceed with diagnostics / error re-set
Obviously most of the people most of the time cut corners..for many things not an issue..

Good result…Bimmercode is not IMHO regarded as well as Protool when it comes to diagnostics and coding..so that may have been an issue.
The FRM try’s to protect itself by locking circuits out that are problematic..after a number of attempts they have to be ‘unlocked’ by coding level tools..in the end the FRM locks up to the extent that it requires bench level intervention..
So you ‘got away’ lightly

I am thankful I found this post!
I have a question; I have tried to find the issue preventing my reverse lights from activating and, I am wondering if a systemic failure with the rearview mirror tilt would cause the FRM to "lock out" the reverse lights.
I have replaced the transmission switch at the suggestion of the local Dealer as a "starting point" and, I have been unable to figure out the X6011 plug indicated on the schematic. The 2011 E89 schematic shows this as a GRY/VIO wire and maybe the (9) beside the connector means it is pin number 9?
I don't find a Gray wire with a Violet tracer in my ebox and if I could identify the connector, would/should I see a 12v signal?
Thoughts?
This is a 2010 E89 manual transmission.
Thank you
