Hi
Haved VCDS for a few years professional and a lot of experience in the repair of most euro vehicle electrical systems and this is the first time posting here.
2007 VW transporter 7HO
Engine ECU
fault code 005687 - Powertrain Data Bus
P1637 - 000 - Missing Message from Electric Load Controller
Only other fault is aftermarket radio. Fault is present with radio connected or disconnected
There is no direct connection for "powertrain can bus" to the Electric Load controller(J519). CAN bus for J519 is on convenience CAN BUS and is connected to CAN gateway.
All installed modules on 'convenience CAN BUS' registering signals and communicate correctly.
All installed modules on ' power train CAN bus' registering signals and communicate correctly.
CAN gateway in instrument cluster shows all controls modules OK. 2wire communication displayed in measuring block
(centrl 1, radio 1, engine 1, ABS 1, etc) measuring blocks 120-129
All installed modules that show measuring blocks 120-129 register correct signals.
CAN BUS signal waveform ok when checked with oscilloscope.
CAN BUS Wiring from CAN gateway(instrument cluster) to engine ecu and central control module(j519) OK.
Vehicle starts, drives and runs good.
0005687 fault code in engine ecu returns immediately when cleared.
Have swapped a know good J519 module and fault is still the same
CAN gateway is suspected fault. will replacing the instrument cluster resolve the issue.
Any help much appreciated?
