63. Measure voltage between PGM-FI main relay 1 (FI MAIN) 4P connector terminal No.2 and body ground.
Is there battery voltage?
YES - Go to step 64.
NO - Repair open in the wire between the No.6 ECU (ECM/PCM) (20 A) fuse and PGM-FI main relay 1 (FI MAIN)
64. Turn the ignition switch OFF.
65. Check for continuity between the PGM-FI main relay 1 (FI MAIN) 4P connector terminal No.1 and ECM/PCM connector terminals A2 and A3
individually.
Is there continuity?
YES - Replace PGM-FI main relay 1 (FI MAIN).
NO - Repair open in the wire between PGM-FI main relay 1 (FI MAIN) and the ECM/PCM (A2, A3).
66. Measure voltage between body ground and ECM/PCM connector terminals A4, A5, A8 and A9 individually.
Is there less than 1.0 V?
YES - Repair open in the wire(s) between that had more than 1.0 V between G101 and the ECM/PCM (A4, A5, A8, A9).
NO - Go to step 67.
67. Turn the ignition switch ON (II).
