Looking for assistance with f01 electrical problems

[audrey.wangfz]

A diagnosis would be greatly appreciated. These are the codes that I received from my f01's electrical problems. Please assist; I have coded and replaced the following: zgb, frm, jbe, bcm, and the steering column and spring. For what reasons are these problems occurring?

The following error messages have been encountered: /// DME [12] - READ TIMEOUT! /// /// EPS [30] - READ TIMEOUT! /// /// ICM_V [39] - Vertical Dynamics Management /// D76C32 -> ICM interface (steering angle, front axle 39.1.2): Signal invalid!
At 55.0.2, the ICM interface reports a signal that is invalid. /// The ICM [1C] is responsible for integrated chassis management. // D014D6 indicates that there is no message about the actual steering angle (driver), with the receiver being the ICM and the transmitter being the SZL/ICM.

I would begin by assuming that ICM is not transmitting, as that is what the vast majority of your codes imply.

I'm sorry, but I don't think that many modules can be considered random pieces.

Evidently, the problem is not with the modules but with the CAN bus or power supply. Communication failure is indicated by the numerous "no message" and steering angle issues.


look beneath the carpet or boot for the battery, IBS sensor, grounds, and main wiring. This may be caused by Earth's low voltage or a faulty connection.

That was the right thing to ask before you sent off the parts cannon.
At the time of my initial scan, a project automobile had fifty or more codes. Focus on a single task at a time.
switch off the ignition, open and close the door, wait 10 seconds, switch on the ignition again, and reread the codes. After that, you should be good to go. What is the first thing that returns? Then put them up here.

Also, I would zero in on the most bothersome symptom or the source of the most severe driveability issue.
Are you in possession of a scan tool?
