BMW Footwell module reset

BMW footwell module frm reset, coding, programming (E90)

BMW Foot Well Module (FRM) controls electrical functions. Here are optional solutions of BMW FRM repair, incl. bmw frm3 repair, bmw frm module reset, bmw footwell module coding, how to code footwell module, footwell module programming, bmw e90 footwell module repair

Location:
This is the module that sits on the drivers side foot well, behind the hood release (in US cars).
Which vehicles are affected?
E90 Series BMW 3 Series Cars
E70 X5 Series
E81,E82,E87,E88 1 Series

What Faults are covered?
Various faults including
Reversing Lights Not Working
Number Plate Lights Not Working
1 or more sidelight,headlight,brake or tail lights not working

What causes these problems?
The FRM Footwell Module monitors & detects short circuit’s either in the wiring (common in the
E90 boot area) or a short circuit bulb. If you do not get the fault repaired quickly then the module
will eventually permanently switch off that particular output. Once it’s switched off it doesn’t make
any difference if you have repaired the fault the light will stay off.

BMW mechanic replace the complete FRM module at a cost of several hundred pounds including coding the module to your car. Here is the procedure in action on a reset we did to a E90 recently.

Solution:
Load/re-write the original eeprom dump (parts requires coding as well)

Vehicle model example:
2011 BMW 3-series E90

PROGRAMMERS confirmed to support this MCU:
UPA USB Programmer
XPROG-M
R270
ORANGE5

EEPROM DUMPS:
My collection of FRM3 dumps – p-flash and EEPROM.

METHOD:
Basically…
1. Erase EEPROM (4096bytes)
2. Write good dump
3. Verify obd working and change vin / VO as if retrofitting used FRM3.
4. Flash with correct zusb number for your vehicle using winkfp.

To connect to the MCU there are 3 methods I’m aware of:
1. In socket – desolder chip
2. In circuit – BDM points – reverse of PCB – see image attached.
3. Direct – test clips onto pins like Pamona Micro Grabbers or cheaper alternative.

Connections to:
BKGD
RESET
VDDR (5v)
VSS

Read FRM module CPU data with VVDI ProgXprog or CG100 ecu programmer. Follow the wiring diagram and read eeprom data.
CPU type 9S12XEQ384

You can see all data shows F, blank data, CPU data may has been lost

Load the original eeprom dump and re-write to CPU.

When do you need coding/don’t need coding?
There are many variants of FRM (Footwell Module) FRM1, FRM2, and FRM3 which all have different controls and functions such as lights, windows and doors. If the eeprom data is exactly the same as your car original data, you do not need coding.  If fog light or aperture still flashes after load original data, you need to do coding.
Device optional:
BMW ICOM Engineering software Ncs expert,
Here is the instruction of Launch X431 Pro, it is easier than ICOM engineering software.
