Ambient Lighting Concerns
Hello. Long time reader first time subscriber.
Little about me, I'm an automotive technician of about 13 years now for Ford Motor Company. I worked at Mercedes Benz for a little while. (Management wasn't fun to work with). Ive always been a Mercedes fan. I own two vehicles a C350 204 and the GLE350 167.
I recently purchased, well about a year ago now, a 2020 GLE and I'm just going through some of the faults the regularly pop up for me.
I have a U1127-87 Communication with one or more color generation and coupling modules on LIN Bus 6 has a malfunction.
It appears that the Ambient lighting is working in all locations that I have found so far. I can't seem to find any information including wiring diagrams on LIN Bus 6 or a location to which LED it is seeing an issue with. Can you guys point me in the direction to checking this out.
I have a B1127-49 AIR QUALITY SENSOR MALFUNCTION-INTERNAL ELECTRICAL FAULT. This one seems straight forward but any additional insight would be great. I believe it is talking about eh NOX sensor that is on the fresh air inlet by the pre-cabin air filter.
And lastly, in the ABS module I have a P0606-47 Internal Control Unit Fault in processor. Runtime Error. I think Ive seen an LI document on this requiring a software update. Would you concur?
