I’m writing a tool that utilises the GM MDI as a pass through device.
I’ve been able to read DID 0x90 and obtain the vin from the BCM using request ID 241 and response ID 641 for the BCM.
Problem is - I’m now trying to read it from the IPC on 24C and a response of 64C (defined on GMBible) but nothing responds to my request (not even an error)
My gut feeling is the request ids are different. Does anyone have any info they can share?
Car is a Opel Corsa-E 2017 model.
Almost identical to the Chevrolet Spark, much of the modules are re-used.
