I am not 100% sure that this ECU is faulty. Let me tell you the details. If i sw on the ignition, i do not have gear indicator. First i thought may be some fuse blown, I checked all the fuse. then check the relay. Found 1 relay blown. replace it. Then tried no luck. called Mechanic. He checked all the electric wiring but there is no problem. We checked the connectors of the ECU. In Connector A the Number 6 wire (green) should supply the ground to the PGM-F1 main relay......... it is according to the wiring diagram but it is not supplying the ground. We tear some insulation from that wire from battaery ground i put a dirct connection to that wire. Now Gear indicator come, try to start the car. It stated but when i shift the gear car jumped and after few second it stopped.
So we come to point that the ECU is not supplying the ground to the PGM-F1 main relay.
Can you tell me is it the problem with ECU?
