george.bryant Posted March 29, 2006 Share Posted March 29, 2006 Does anyone know how to run an ECU Disanostics on a L series fuel injected motor...and if they do, does anyone have the codes? I ask cause no one can tell me, but then i wonder why does it have a ecu screw and a l.e.d. Quote Link to comment Share on other sites More sharing options...
AK-Z Posted March 29, 2006 Share Posted March 29, 2006 There is no daignostic on the ecu. These were made before OBD I. OBD I came out in 91 I believe and stands for On Board Diagnostic. Only thing the I believe to a monitor would be the LED on the ZX ECUs that I believe was used to see if th O2 sensor was out. Quote Link to comment Share on other sites More sharing options...
