Starter Switch Signal Circuit Troubleshooting

NOTE: Transmission in Park or neutral




1. Measure voltage between PCM connector terminals A24 and B20 with the ignition switch in the start position (III).
Is there battery voltage?
YES - The starter switch signal is OK.
NO - Go to step 2.
2. Inspect the No.13 STARTER SIGNAL (7.5 A) fuse in the driver's under-dash fuse/relay box.
Is the fuse OK?
YES - Repair open in the wire between the PCM (A24) and the No.13 STARTER SIGNAL (7.5 A) fuse.
NO - Repair short in the wire between the PCM (A24) and the No.13 STARTER SIGNAL (7.5 A) fuse or the PGM-FI main relay. Replace the No.13 STARTER SIGNAL (7.5 A) fuse.
