2011 F10 525i USA EPS problem

AvechuchoAxel · Aug 20, 2013

I'm working on this car sor several days now fixing airbags and some electrical problems... After all the electric repairs I have the EPS faulty.

HERE ARE THE DTC's out of the ICM (Integrated Chassis Module)
EPS is not responding / no communication

D019BF mESSAGE (Actual steering torque, driver, actuator 49.0.2) missing, receiver ICM transmitter.

D016A5 Message (display, check cotrol driving dynamics 02,218.11.32) missing, receiver ICM, transmitter EPS

D015C4 Message (electrical sterring,front axle, 234.1.2) missing, receiver ICM, transmitter EPS

This vehicle had a frontal left collision. EPS harness was damaged but properly repaired (spliced-soldered-shrink tube). Pinponted wires and terminals at the EPS unit looking OK.

Fuses # 1, 8, 13, 24, 39, 43, 45, 134 checked.

Is there anyting that I'm missing or overlooking?

Thanks!

It's quite possible that a crash that severed the cable could have fried attached electronics as it was happening. It's also possible that your cable splicing is not perfect. I would have considered a new harness..

I was thinking out about the posibility of a bad splicing, so i just run a paralel harness. Same thing. !! On the CAN (twisted wires) I have a reading of 96.7 / 100 ohms .

I suspect that the EPS was fried out.... but is a expensive bet!

Can't find online any diagram or wiring specs that can lead me to the antecessor or previous modules on the can.

any other diagnostic tip available?

Can't help you beyond that. FYI there is no F10 525 in the USA. There is a 528.

YES..YOU ARE RIGHT IT IT A 528i 6L engine.
BTW I found the problem on the power supply to the control module. CAN was OK, but power supply was interrupted even with fuse 34 un good shape. So I can sleep now until the next headhache arrives!!

Thanks!
