CAN Bus troubleshoot
Hello,
I'm trying to fix a problem in the CAN bus ( U1900 and other node missing etc...)
I have 12.7 V on ignition off
I have 2.7 V on CAN_H and 2.4 V on CAN_L which seems to be good
But when i mesure the resistance between H and L , i have 0 ...
is it possible ? or my DVOM is dead ? ( or at least , not having his ohmmeter function ...)
Also , i don't seem to find the main connectors wiring, its like a big cube ... with many wires, one on right up from fuse box , and one on left, i don't find the name
Thx

Hello,
I have SDD ... i bought a new power supply 30 A 9mv ripple , reinstalled SDD, removed firefox ( SDD works better with Internet Explorer)
I ordered some piercing probes / Needle probes
Also I ordered new DVOM , i found 60 ohm between pin 6 and 14 from Data Link Connector and correct voltage
Next step is to test the CAN lines continuity between ABS/DSC module ( on MY2009 there seems to be only 1 module refered as DSC module) Junction Box
thx
