Reconnect ECM/PCM connector E (31P). Turn the ignition switch ON (II). Measure voltage between body ground and ECM/PCM connector terminals A2 and A3 individually. ECM/PCM CONNECTOR A (31P) Wire side of female terminals Is there battery voltage? YES - Go to step 54. NO - Go to step 48. Turn the ignition switch OFF. Remove the PGM-FI main relay 1 (A). LHD model: RHD model:

Turn the ignition switch ON (II). Measure voltage between the PGM-FI main relay 1 4P connector terminal No. 2 and body ground. Wire side of female terminals Is there battery voltage? YES - Go to step 52. NO - Repair open in the wire between the No. 6 ECU (ECM/PCM) (15A) fuse and the PGM-FI main relay 1. Turn the ignition switch OFF. Check for continuity between the PGM-FI main relay 1 4P connector terminal No. 1 and ECM/PCM connector terminals A2 and A3 individually. Wire side of female terminals Is there continuity? YES - Replace the PGM-FI main relay 1. NO - Repair open in the wire between the PGM-FI main relay 1 and the ECM/PCM (A2, A3).
