REPAIR OF BMW E SERIES FRM3 Footwell Module
Numerous BMW sensors send signals to the BMW FRM module, sometimes referred to as the Footwell Module or Light Module. As a result, you will experience a variety of strange malfunctions when the FRM develops a fault, including: windows that won’t go up or down, lights that turn on and off, buttons on the head unit that aren’t illuminated, etc. Please continue reading if your BMW has a Footwell Module and you are exhibiting the same symptoms.
Price: PS120 for postal service (24–48 hours); while you wait, bring your car or a FRM.
The BMW FRM module is where?
Numerous BMW models come standard with the BMW footwell module (FRM). The FRM, a 128 pin, three plug control device with two 51 pin connectors for the main wire harness, is situated in the right kick panel. Additionally, the instrument cluster and dashboard share a single 26-pin connector for operating functions like the interior and external lighting. Throughout the whole BMW lineup, the FRM frequently fails.
Customer grievance
BMW owners have reported a wide range of typical problems that point to a bad FRM. When opening and closing the doors with a remote control or using the indication stalk while operating the vehicle, the indicators did not work. Owners have also mentioned inside lights not working or the headlights staying on, as well as an intermittent loss of power window and side mirror function.
- Power windows not working
- Inoperative indicators
- side mirrors not working
- Inoperative interior lights
- No interaction between the FRM and the scan tool
- Frequently, the issue appears after the car has been jump-started.
- keeping the headlights on
Diagnosis:
After a car has been jump-started or had its battery replaced, the problem frequently reappears. If any of the listed issues are present or if OBD (On-Board Diagnostic) plug communication is not feasible. The FRM may also be shown to be in fault if fault codes associated with its operation are obtained from other modules.
Solution:
Dealerships frequently replace faulty FRMs; this can be expensive and necessitates programming at an additional cost to the owner. Since the original cause of the issue has not been resolved, a replacement is more likely to malfunction once more.
The FRM can be repaired by Injectronics, sparing you from paying further programming fees. Located behind the right kick panel is the FRM. For testing or maintenance, you need a key and a Central Access Module (CAS).
Please make sure the vehicle’s battery is fully charged and tested before refitting the FRM module, as this is the most typical reason for FRM failure, as was previously noted.
The FRM module regulates what BMW does.
In the drivers-side footwell, the BMW Footwell module (FRM) serves as an electrical hub or node. The FRM connects with the dashboard, regulates the illumination, receives signals from the doors, and instructs the adaptive headlights.
What results in the FRM module failing?
The majority of E90, E91, E92, E93, and E70 cars commonly experience the BMW & Mini FRM / Foot Well Module failure. Typical signs of a failing FRM device include
When the vehicle’s battery has been disconnected or when it has been jump-started, FRM / Footwell Modules frequently malfunction.
Describe the BMW FEM module.
The main controlling component of the car’s electrical system is called the Front Electronic Module (FEM). The Front Electronic Module (FEM) also serves as the entry point for the other control units.
How can I tell if my FRM module is defective?
The FRM modules are delicate devices to start with. At the driver-side footwell, they are firmly fastened. You will need to remove a few screws in order to reach it because it is out of reach. Here is further information on uninstalling the BMW FRM.
However, even if these electronics are protected, a slight water penetration or voltage change might still cause damage to them. Jump-starting or changing the battery can frequently damage your Footwell module.
This may result in a number of issues at once. A list of these issues that are brought on by a broken FRM module is provided below.
- Ineffective Headlights
- Indices are not functioning
- No interior lighting
- No high beams
- Power windows are not functioning
- Always-on dashboard service light
- Climate Control Fails
- Rear lights won’t turn on or off
- no automated mirrors that fold
It is always preferable to send a defective footwell module for repair in the event of a defective FRM. You may also get a brand-new one, but it would incur a lot more costs.
Costs for new FRM modules range from $400 to $500. Then, you’ll need to pay extra to have it programmed according to the specifications of your car. Given how delicate they are, these devices’ warranties are also just a limited time.
In other words, a new Footwell module will set you back at least four times as much as a repair. You can read one of our articles on this subject here to learn more.
What does FRM in vehicles mean?
An electrical nodal point in the footwell on the driver’s side is called the footwell module (FRM). The footwell module receives the door signals and manages the lights. The adaptive headlights are likewise managed by the footwell module.
How is an ignition module changed?
The ignition coil and module assembly should be located. Start at the spark plugs and follow the wires. The coil and module assembly, which may be positioned on the engine’s back, is connected by the wires. Your automobile may need to be safely supported on two jack stands after being raised to the front with a floor jack. Pull off the electrical connectors for the coil assembly from below the engine. Using a ratchet and socket, remove the mounting bolts for the assembly. Using a ratchet and socket, remove the assembly from the engine and then remove the coils. Install the new ignition module after removing the old one from the base plate. The engine should have the coils and module assembly installed. Lower the car and attach the electrical connectors.
- To identify or locate components, see your owner’s manual or the vehicle service manual. Most car parts stores sell them for a price, and most public libraries offer free consultations.
- tool for Phillips screws
- Set of ratchets and sockets
- If necessary, a floor jack and two jack stands
- Grease for silicon dielectrics
- The back of the majority of ignition control modules needs to be greased with silicone dielectric grease before being installed. The grease guards against circuit damage and overheating of the module. Installing the module on your specific car requires that you adhere to the manufacturer’s instructions.
Describe the BMW coding tool.
BMW iDrive coding, in its simplest form, entails modifying your car’s software in order to unlock new functions or modify how existing ones function. Most of the time, such capabilities are already included into your iDrive by BMW; all that needs to be done is for coding to enable them. iDrive is already built to accommodate a rear view camera in cars that come equipped with one from the factory, therefore activating a retrofit kit merely involves unlocking those software capabilities. One example of such code is to activate an aftermarket backup camera.
Does FRM need to be coded?
For a new Footwell Module (FRM) to work properly after installation on a BMW, it must be coded. Front power windows, side mirrors, and interior illumination that are not properly coded for the FRM may not work.
In a video tutorial produced by BMW-E90-HQ, the procedure for coding a new Footwell Module (FRM) on your BMW is demonstrated step-by-step. View it in the following video:
The Footwell Module (FRM)’s primary job is to act as an electrical hub, collecting signals from the driver’s door switch block, hazard/reverse/brake light switches, ride height sensors, front door contacts, and driver’s side door lock. It performs the role of a gateway module, analyzing the signals and using them to operate the power windows, outside mirrors, central locking system, adaptive headlights, and interior and external lighting.

Can Carly reload the form?
The FRM cannot restart after being totally shut down, which is the root cause of the error. However, upon coding, the FRM needs to be restarted in order to load the new codings.
How much does a win module replacement cost?
While parts are priced between $242 and $332, labor costs are predicted to range between $56 and $71. Taxes and other costs are not included in this range, nor are your particular vehicle or geographic area taken into account. There might be more repairs required. This range is an average for all on-road cars.
Does FRM regulate AC?
The footwell module controls several of the car’s “body” features, including the electric/power windows, the air conditioning and heating fans, the exterior and interior lights, and the outside mirrors. It receives signals from a variety of sensors on the vehicle.
How long does a power control module replacement take?
Do Windows updates annoy you to no end? If so, we’re sorry to break the news to you. The computer in your automobile might need to be updated for optimal performance.
The PCM employs software to manage the car’s systems. It understands, for instance, that you need extra power when driving up a steep hill.
Every potential issue will be considered by the programmers, and solutions will be built in. But just like Windows programmers, they are subject to error or may overlook a specific problem.
Maintaining the performance of your car requires downloading the updates. Most frequently, a manufacturer will publish an update or recall and notify the registered owner of the vehicle that a software upgrade is required.
Almost always, these updates are provided without charge. Simply bring your car to the dealership and schedule some time for the changes to be made.
However, in order for it to function with your car if you bought a secondhand PCM as a replacement (often from a car that was totaled in an accident), it will need to be reprogrammed.
Where you go for the upgrades will determine the cost. Since there are no parts needed, the cost will be normal labor. Depending on the service location you select, costs could range from $80 to $150.
The procedure takes roughly 30 minutes, but you should be aware that most car electricians charge for at least an hour of labor. One of the few instances we’ll suggest a dealership over a mobile mechanic is for PCM reprogramming.
What component manages the AC?
Modern automobiles have complex AC systems that may be fitted with a variety of sensors and parts. All of the AC system’s electronic operations are managed and controlled by the AC control module. In order to maintain the proper temperature in the cabin, it reads data from both inside and outside the car. It then uses that data to regulate and alter the AC system as necessary.
Since the AC control module essentially regulates the entire electronic component of the AC system, any issues with it should be evaluated because they may have a significant impact on the entire system. Typically, when a control module starts to malfunction, it starts to exhibit symptoms that can notify the driver of a problem.
