Hi All,
Im wondering if any of you can help me with a couple of codes that my ECU has kicked up. I've done the usual Google search and haven't really got anywhere...so...I've come to the guys that know this stuff.

The 2 codes im getting that cant be cleared are 1-2-4 and 1-2-6

Hopefully I can get to the bottom of this.
Many thanks in advance,

...Guy

What pin of the OBD2 port are you getting them from?

Are those engine DTCs or EEC DTCs? Those numbers are codes for the fans on the interior temperature sensors above the doors.

My Code reader was reading ports 5 6 and 16. I thought this was for the engine management, not the ECC?

I think you are getting multiple codes from multiple modules.

Is this a 95 T5R with a diagnostic under the bonnet or a 96 with a obd2 port in the console?

I think those are the EEC ports.

ECU is 3, 5, 16

Those codes probably mean that your interior temp fans are clogged up with headliner foam, etc.
Just went through all of this on the wife's '97 GLT.
