Hi My friend
I have this problem with nissan-forklift MC01Z15 k15 engine.
I check the all wiring_relay.fuse box. I think My ECU have problem.
I checked all the wiring from ecm to relay box and relays its fine. I checked the green line of the white line coming from the ecu and it does not bring any voltage or signal to the relay box to activate the relays.
What I should to clear and Repair this.
I see error code F-04 and P-04.
