Does anyone know where this is? I was able to catch a code today when my PSM light came on, and I went into limp mode at highway speeds.

I pinout would be nice, so I can trace the can-bus wiring.

DTC 1314 - DME

Googling around, sounds like loss of connectivity to the DME, all other modules have not logged any issues talking to the DME.

This is the last of a massive wire harness failure I had late last year, after repair this is the 3rd time this has popped up.

DME has no codes, may be a red herring but the AWS advanced weight module, I have trouble talking to it and my "Passenger Airbag light Disabled" no longer lights up.

Found it, under the DME, in the engine bay, it uses 2 of the can bus networks (dual nic).






Shares a bus on CAN DRIVE and gets the DME communication there, if the DME connection is lost, PSM shuts down in failsafe.

It can talk to the TCM, Airbag and Level suspension, DME and a few lesser modules. I need to understand what that brown/red wire, the black was ground and the other wire, the red/yellow (constant power) all did here. Brown/red was my main culprit and makes me think I lost power to the gateway, which made all the other modules unreadable, or all the modules in DRIVE CAN are on the same power circuit.

Red yellow does provide power to the Gateway Computer.



Brown/Red line I soldered, it goes to power the Driver Identification Control Unit, it too is on the CAN DRIVE Bus as well as the regular bus.

Not sure what it does, anyone? It has a Diagnosis line, whatever that means.

The relay 433 I replaced, was the relay that goes to this unit too.
