Right, I cannot connect to the air suspension ECU nor the airbag ECU.
I can talk to the instrument cluster, ABS, engine, gearbox, transfer box, parking sensors, steering angle sensor.
The ABS ECU has the air suspension can error stored. I have done countless hours of research on forums and am totally stumped. I find it hard to believe the can bus is down as I can talk to ECU’s. I also scoped the can bus and it seems to be fine. I scoped the K bus and I’m not sure if it’s ok or not. I have tried disconnecting every ECU connected to the K bus and it has no effect. Only module I didn’t disconnect was the LCM but this appears to be on the I BUS. The only bits which don’t work on my l322 are front headlight wipers, rear window wiper, steering column lock doesn’t engage, steering column doesn’t motor in nor out but does go up and down, not sure if seat memory functions work, not sure if the dipping mirror works as not used it at night yet and satnav thinks I’m miles away from actual location. Oh and radio reception is rubbish.
Does the EAS ECU talk to the diagnostics via can bus or k bus? Whats the chances of an air bag module fault which doesn’t illuminate the light on the dash ie it goes off normally? I’m really pulling my hair out I’ve this now!
