The indicators are flashing at a rate of 120 times per minute. What is the cause of this phenomenon?

[James_Cam00]

Greetings.

The issue arose subsequent to a one-month period of absence during which the automobile was left unattended.

The indicators exhibit a frequency of 120 flashes per minute. (notwithstanding, it successfully passed the Ministry of Transport inspection)

The evaluations that I have conducted

After doing a diagnostic test using ISTA+, no errors were detected.
The FRM module was subjected to diagnostic testing using the INPA software, which revealed no detected faults or counters requiring resetting, since all values were recorded as zero.
All lighting fixtures are functioning properly, and as a precautionary measure, all bulbs have been changed.
There are no caution lights illuminated on the dashboard.
The water infiltration in the lights was examined and found to be satisfactory.
An inspection was conducted on the wires that are routed via the boot opening, revealing no signs of fractures or impairment.

What aspects or elements have I overlooked or failed to consider?

Upon investigation, it has been determined that a flasher relay is located in the trunk area in close proximity to the battery. Despite diligent efforts, the relay housing unit remains elusive and cannot be located.

Was there a Technical Improvement bulletin issued for the E91 in response to this issue? In my opinion, it was necessary to replace the back lights. Although there is a possibility of error, it may be beneficial to do more investigation.

It would be advisable to initiate a telephone inquiry to ascertain the presence of any potential recalls pertaining to the item in question.

The issue at hand pertains to the grounding of the rear taillight on vehicles like as the E46 330d and E92 335d. It seems that the earth pin or cable may have experienced damage or near damage, resulting in the need for a repair. To address this, a stronger wire is used to establish a new grounding connection. A handbook was consulted to facilitate this process, which was found to be very straightforward.The necessary materials for this task are a wire and a set of spades.

It seems that there may have been a recall on the mentioned product, specifically pertaining to the earth wires which have been upgraded to thicker versions. Despite this, I proceeded to inspect all of the earth wires and found no apparent issues.

I revisited the ISTA+ programme and really engaged with the fault discovery, diagnosis, and subsequent outcomes.

The result indicated that the FRM module requires replacement, despite the fact that all of my lights are functioning properly. The phenomenon seems peculiar from my perspective.

I would recommend inspecting the wire boxes to see if any pins or holes exhibit signs of charring or burning.

I purchased a PL2 FRMII E90 E91 NSW module from eBay at a price of £6. The user's text may be rewritten as follows: The user's text can be modified to reflect an academic tone.

The coding procedure was executed using NCS Expert and WinKFP, resulting in the successful resolution of the issue. Consequently, all lights are now functioning properly, and the indicators are flashing at the appropriate pace.

The following procedures are outlined to facilitate a straightforward and precise process.

To initiate the WinKFP software, the user should open the application. Once opened, the user may choose the F1 Comfort mode.
The purpose of this communication is to provide an update to the Electronic Control Unit (ECU) of the F3 system.
Please locate the FRM module within the provided list. The specific FRM module in question is FRM2.
Please choose a module from the list of available FRM modules.
Please input the Vehicle Identification Number (VIN) in the designated field labelled "F4". Once completed, press the "F8" key to indicate that you have finished. To initiate the programming of the ZB update, press the "F3" key. Please note that this process may take several minutes, and it is important to ensure that your battery is fully charged before proceeding.


To start the NCS Expert software, please follow these steps: 1. Open the NCS Expert application. 2. Navigate to the "File" tab. 3. Select "Load profile" from the dropdown menu. 4. Choose the desired profile for manipulation.
The F1 race starts with the initiation of the F3 chassis.
I have selected E89, specifically pertaining to my E91.
The user is instructed to choose the CAS (Central Authentication Service) option. They are then prompted to go back by using the F6 key. Finally, they are advised to process the ECU (Electronic Control Unit) by pressing the F4 key.
Select the Non-Functional Requirements Management (NFRM) option. Proceed to change the job to FA_Write by pressing F2. Execute the job by pressing F3. To return to the previous screen, press F6. To start the process, press F1. For chassis-related tasks, press F3.
Please choose the Non-Functional Requirements Management (NFRM) option. To go back, press the F6 key. Verify the job name as SG_CODEREN. To proceed with the ECU processing, press the F4 key.
