BCM 0052 and 0050 codes

Post by **oragex** » 28 Sep 2020, 12:59

Has anyone had these codes ? I did a search but nothing clear other than 'internal permanent fault'. The CEM also has a 1A5F code that won't clear. Interestingly, there is no warning light or message. The ABS works fine on all wheels - tested during winter on ice. I can also hear the ABS pump humming when braking. Car is FWD 2003 STC

Is correct BCM installed on the car?

Two things common to both BCM DTCs are electrical distortion scrambling the data and defective control module. Pull the BCM connector and clean it. Check wiring for shorts and opens.

CEM-1A5F is CEM to BCM communication. This could be dirty connectors or wiring also.

Most likely it is an issue on the CAN high speed network not the electronics.

I haven't replaced the BCM but don't know its history from previous owner. Car was bought with 100k miles
Will look closely to the wiring and connectors

In this case will be cool if you show me couple screenshots:
Vin, detailed info about car and tab Network, click on BCM on the image and show me SW numbers also.

VIDA says my driver power seat has a communication fault (memory wont work) but the seat works fine, i use the memory function all the time. I wouldnt worry too much about it.

What about VIDAs tab Network?

I don't have Vida. I use a regular scanner

Can you see BCM software numbers use it?
