28. Measure voltage between PGM-FI main relay 1 4P connector terminal No. 4 and body ground.
Is there battery voltage?
YES - Go to step 29.
NO - Repair open in the wire between the No. 8 FI ECU (ECM/PCM) (15 A) fuse and PGM-FI main relay 1.
29. Check for continuity between PGM-FI main relay 1 4P connector terminal No. 3 and ECM/PCM connector terminal E5.
Is there continuity?
YES - Test PGM-FI main relay 1. If the relay is OK, update the ECM/PCM if it does not have the latest software, or substitute a known-good
ECM/PCM, then recheck. If the symptom/indication goes away with a known-good ECM/PCM, replace the original ECM/PCM.
NO - Repair open in the wire between PGM-FI main relay 1 and the ECM/PCM (E5).
30. Reconnect ECM/PCM connector A (31P).
31. Turn the ignition switch ON (II).
32. Measure voltage between body ground and ECM/PCM connector terminal A4.
Is there battery voltage?
YES - Go to step 39.
