Diagnostic Code Query

[steelroe]

We know that the diagnostic codes for the engine can be extracted using the earthing procedure here http://www.ftowa.com/html/workshop/workshopart07.html

But this only extract engine fault codes. So how do you extract the Automatic transmission codes. Does the above procedure also extract the trannny codes vis the "N" loght flashing.

Todays mission is to figure this one out. Or does anyone already know??

i have used it to get an error code for the input shaft speed sensor.

cant find the file for the meaning of all the error codes maybe
someone else here can help you with it

I should have read a bit more before I posted this.

Once you ground terminal 1 of the diagnostic connector, codes are flashed for the relevant ecu. i.e

Engine Codes are flashed via the engine management light.
ABS faults are flashed throught the ABS indicator.
TCL are felashed through the TCL indicator.
Automatic Tranny is flashed through the "N" light. (Note the gear lever has to be in the "P" position to flash codes from the AT ecu.

Could something be rigged so you could just flick a switch to start a diagnostic?
It'd be easier than having to unscrew panels and ground wires...

I have already done this with a very smal toggle switch. Much easier that way alright.

I thought mine had it, turns out it was just a switch for the parking sensors...

[steelroe]

you can use that switch if you want

i would ground the wire to the brake pedal

Theres closer grounding points than the brake pedal (unless you wanted to use the brake a switch in some some mad sort of way!).
