Diagnostics Problem

awillemsen · Mar 11, 2010

We've had our P38 4.6 Vogue (2000, X plate) for about 6 months now, and it's just had its first service, at an independent (one man band, Jaguar specialist, but seems to know his way around a P38). He reported that when he plugged in his diagnostic equipment, it wasn't being powered up by the car - and when he powered it via the cigarette lighter, it didn't recognize that the car was there. The plug is showing some corrosion, so he suggested booking it back in again at some point in the near future to try and get the diagnostics working. Is this a common issue with P38s, and what is likely to be wrong - a plug/wiring problem, a problem with the car end of the diagnostics, or a problem with the garage's diagnostic equipment?

Many thanks for any help/advice

Corroded OBD connector.

I am with Datatek on this one too.
Not only can there be corrosion on the obdii connector itself, but also the connection of earth to the body has been known to be problematic.

It measures fine until you put an amp or two of equipment on it.
