Check engine light


Recommended Posts

Hey guys, the check engine light came on in my '88 turbo today. i can't find the diagnostic link for the life of me! The owners manual says to pull the ecu and count the flashing lights. Is that right? How do you get the light off? It runs fine... It is bone stock. Thanks Jason

You're lucky...88-89s have a CONSULT connector in the passenger kick panel by the ECU to do an auto code check. The other option is turning the screw on the ECU and watching the lights flash. You do NOT have to do all 5...

Keep in mind the diagnostic connector is NISSAN CONSULT, meaning you'll need a consult adaptor and software for whatever scan tool you're using. Also, CEL is Cali emissions only. If you look in the FSM it'll note the few things that are check engine light worthy. Its likely Injector Leak, EGT, or EGR.
