Hey all,

 

Having problems with reading my ecu codes. Pulled the ecu to turn on the self diagnosis and theres no mode selector knob on it! Just a hole and the led, stuffed a screwdriver in but nothing in there but diodes and stuff! Next pulled all the under dash off to try and find the consult port to bridge the pins to select diagnosis mode and theres no port anywhere!! Maybe i am just not seeing it but really have looked everywhere. Its a 93 UK spec TT manual, did they put them somewhere else on the UK? Help!!!!

 

Reason for needing codes is she has an occasional missfire/hesitation on light throttle. Comes and goes, give her some more (onto boost) and she clears out. Bit of a fuel smell also.

 

Sorry if i seem abit dense but used to the RB/Skyline setup and the differences are 10 fold. :)

 

Thanks in advance all Zed gurus!

Anyone?

The mode selector is recessed in a hole and it is possible to miss it with a screwdriver and put it to one side of the screw, if it's in situ on the car and you can't see it very well.

Not all ECUs have that little potentiometer on the board. Didn't realise that some cars didn't have diag ports though.

 

The problems you have may not be solved through the diags, a ConZult may help. As it's intermittent I would start checking the coilpack electrical connections.

Found the port! Was pulled off and tucked way up under the dash due to a rough alarm install. Checked and code 55! Will start by checking the coilpack plugs or start a new thread. Cheers troops!

this is a good guide... or at least worth a read..
