Volvo Repair Questions? Ask a Mechanic for Answers ASAP
Hi my name is ***** ***** am here to assist you Today what was the original issue it was at the dealers for a diagnostic test was it a drivability issue or had it just put the engine warning light on.
Is that all the codes stored now.
Has the BCM (Body Control Module) been looked at / checked.
I think it has more than one issue but you need to start at the BCM.
You would need to use an Oscilloscope to look at the wave format on the CAB BUS lines.
CAN (Control Area Network)
rather than CAB that was a typing error.
You need to find someone that is confident using a scope try http://www.boschcarservice.com they are independents but they will know how to diagnose CAN issues.
You said "there's no signals being passed for the injectors after checking with noid lights" is this correct.
It all goes back to using a scope and looking at wave formats crank / cam wave format for example see image
Keep me posted with how you get on.
No problem regards Gavin.
