data link connector Pin 5 wire routing
data link connector Pin 5 wire routing
I am looking at the wiring diagram in the service manual and on page 710 or section 8E-8 for data link connector 5 I am not finding connector c227 which should be a blue connector left of the steering column behind the instrument panel. Anybody know the routing of Pin 5 to connector C4 for the Powertrain control module. I have no continuity, but can't trace to the connector. I have no continuity at either the PCM , C219, or at the fuel sensor connector which leads me to C227. circuit in question from manual below.

I think the diagram on page 8W-30-7 of hte 2007 service manual or page 8W-30-9 of the 2005 service manual is easier to read.
That is a ground pin. The ground is provided inside the ECU/Powertrain Control Module. The ground is provided to the fuel tank pressure sensor and the data link connector.
It is POSSIBLE there is only a ground when the ECU/PCM is powered up, but I sure cant say for sure. You have your path marked wrong, your car is an "except export" version.

Re: data link connector Pin 5 wire routing
Thanks,
figured out the POS wired the ground pin from the coolant sensor to pin 5 and pin5 ground pin to the AC pressure switch ground and the coolant ground to the AC pressure switch, or something like that. They are all brown with yellow so I can kind of understand, but one wire at a time and test wouldn't be that bad would it?
I now have continuity from pin 5 to C4 at the ECU/PCM and continuity with other pins for ECU and AC pressure switch and coolant switch. Wonder if a bunch of lights will go out on the dash now
Have to wait on some more wire loom tape as I had to take everything apart and ran out just before I got it done of course.
Weird in the except export as the manual I have lists the connector colors wrong then???? Will have to go search for those other year model manuals.
