Diagnostic Socket

[whiteman]

:duh: was bored last night and me and my mate were trying to decide if the diagnostic socket under the bonnet, near ecu is the one they use to find faults.

I was reading that they have to be approx 3ft from drivers seat so that means it is inside the car somewhere, anyone tell me where inside the car it is, if it is..

also the tool required to read, is it a 'data logger' or a OBD 2 scanner..

Just need to know what is required to read the faults on car if and when I have any as mate has got most of the gear to do this type of stuff,.

cheers

Well I believe it's under the steering wheel (at least on the IS300 it looks that way). Under the panel that your knees are if you look upwards you'll see a white plug with a black cap on it. As far as I know that's the diagnostic plugin point, only found mine as I I felt the cap brush against me as they'd left it off.

YEP bottom of the knee panel below steering wheel, also another next to the ecu, these can only be read using OBD II complient machines
