Re: CAN Bus wave pattern for 2007 Jeep GC WK?

OK, so here's the f/u: 1. I connected my Autel MS906BT to the BOB and I was able to get a normal CAN Bus pattern at 6 and 14. 2. Pins 1 and 13 have no voltage with KOEOff or KOERunning. There is no continuity between 1 and 13. The wiring diagram must have an error. Thank you very much for your assis...

Re: CAN Bus wave pattern for 2007 Jeep GC WK?

Thank you for the wiring diagrams. Tomorrow I am going to do a number of things:
1. Monitor 6 and 14 with a bidirectional scan tool attached.
2. Check 1 and 13 for voltage and resistance.
3. Check 1 and 13 for a trace.
I'll let you know what happens.

Re: CAN Bus wave pattern for 2007 Jeep GC WK?

The 7000 page shop manual pin out for the DLC on the 2007 Jeep GC WK shows no circuits on pins 1 and 13. It only shows CAN C Diagnostic on 6(+) and 14(-). I'll check myself later this week if there is anything on them.

Re: CAN Bus wave pattern for 2007 Jeep GC WK?

the two traces are not close to being a typical CAN Bus pattern. I used the same set up, same settings on a Chevy Suburban with no problems. Hi. There is a fundamental difference in the connection on the diagnostic connector DLC 16. DLC 16 Chevrolet: 6 pin - high speed GM Lan BUS+ 14 pin - high spe...

Re: CAN Bus wave pattern for 2007 Jeep GC WK?

Pins 6 and 14 are supposed to be CAN C (high) and CAN B (low) Well Yes and No !! Common misconception nowadays, it does depend on the Topology of the Network and whether or not the car has a Communication Gateway. A wiring Diagram will tell you that. The days of seeing anything other than "Diagnost...

CAN Bus wave pattern for 2007 Jeep GC WK?

Using a Pico 4425 and Pico BOB I've been trying to get a CAN Bus trace on a 2007 Jeep Grand Cherokee Limited 5.7L . Pins 6 and 14 are supposed to be CAN C (high) and CAN B (low). There is very little voltage change on a +/-5v scale. It looks like one line above and one line below 2v with noise. When...

Re: Forum password & Waveform Database access

Is there a way to change my Password? I just did a reset and there is no way I'm going to remember the password that was generated.
Thanks.
I found it in Control Panel. Sorry for the bother. Thanks
