1A-45 Engine General Information and Diagnosis:
2 Main relay circuit check
1) Turn ignition switch to OFF position.
2) Remove main relay (2) from main fuse box.
3) Check for proper connection to main relay connector at
“BLK/YEL” and “BLK/RED” wire terminals.
4) If OK, measure voltage between “BLK/YEL” wire
terminals of main relay connector and body ground.
Is voltage 10 – 14 V?
Go to Step 3. Open wire in “BLK/YEL”
circuit.
3 Main relay check
1) Check for main relay referring to “Main Relay, Fuel
Pump Relay, A/C Compressor Relay and A/C
Condenser Fan Relay Inspection in Section 1C”.
Is main relay in good condition?
Go to Step 4. Replace main relay.
4 Ignition signal check
1) Disconnect connectors from ECM with ignition switch
turned OFF.
2) Check for proper connection to ECM connector at “G04-
23”, “G04-10”, “G04-6”, “G04-5”, “C41-1”, “C41-2” and
“C41-3” wire terminals.
3) Turn ignition switch to ON position.
4) Measure voltage between “G04-23” wire terminal of
ECM connector and body ground.
Is voltage 10 – 14 V?
Go to Step 5. Open wire in “BLK/
WHT” or “GRN” circuit.
5 Main relay circuit check
1) Turn ignition switch to OFF position.
2) Install main relay to main fuse box.
3) Measure voltage between “G04-10” wire terminal of
ECM connector and body ground.
Is voltage 10 – 14 V?
Go to Step 6. Go to Step 8.
6 Main relay circuit check
1) Remove ECM from vehicle body referring to “Engine
Control Module (ECM) Removal and Installation in
Section 1C” and connect connectors to ECM.
2) Turn ignition switch to ON position.
3) Measure voltage between “G04-10” wire terminal of
ECM connector and body ground.
Is voltage 0 – 1 V?
Go to Step 8. Go to Step 7.
Step Action Yes No
