Thread: 1994 disco - where is the ecu display ?

The ECU does not have a display. There is a diagnostic plug under the dash if you have a reader. Lots of things can make it run ruff, leads, dissy cap or rotor, air leaks but I would start by checking the MAF and clean or adjust. There was a great setup procedure on here if you search.

Pretty sure that 94 discos don't have any diagnostic plug. That appeared with the disco 2.

Cheers

Disco 1 does have the Diagnostic plug. My '96 and '97 Discos both have one. You can buy a reader I think or you can use the blink code procedure. You need to make a wire up and insert it into pins 5 and 15 from memory. Look up disco 1 blink procedure for directions.

I should have been a bit clearer.

Later models did have an OBD Diagnostic plug but the earlier models did not and only had a unique land rover specific plug/s and codes. I think it was around 1995/96 the change was made when OBD compliance started becoming mandatory in a number of countries.

My old 94 range rover had separate diagnostic plugs for Engine, SRS system, Air suspension and Alarm/security.

Thanks for all the answers. I will start with the MAF first and wait for the 14CUX fault reader to arrive.

Would be a good idea to just disconnect the MAF ? I should get a default value then which could be better than the hopping the car does sometime now.
