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.
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 front doors
- Driver’s door lock
Power supply voltage being unstable can cause lost CPU data thereby resulting in no communication with footwell module using BMW ISTA Diagnostic or any other scan tool.
This service requires donor FRM module that is compatible for vehicle. We will transfer data over to donor and test that all is in SYNC with CAS module.
***We do have EERPOM data repair which is tested first before attempting data transfer. price varies. We will update customer once ECU’s are in our lab.
