Turn the ignition switch to ON (II).
Measure the voltage between terminal No. 1 and body ground.
- If there is battery voltage, go to step 5.
- If there is no voltage, check for:
- Blown No 36 (10A) fuse in the under-dash fuse/relay box.
- An open or high resistance in the wire.
- Faulty IG2 cut relay.
- Faulty under-dash fuse relay box.
Measure the voltage between terminal No. 3 and body ground with the transmission range switch in R position.
- If there is battery voltage, replace rearview mirror (see REARVIEW MIRROR REPLACEMENT .
- If there is no voltage, check for:
- Blown No. 10 (7.5 A) fuse in the under-dash fuse/relay box.
- An open or high resistance in the wire.
- Faulty dash/relay box.
- Faulty transmission range switch.
Turn the ignition switch to LOCK (0)
Reconnect the 7P connector.
Turn the ignition switch on ON (II)
Measure the voltage between terminal No. 2 and body ground.
- If there is less than 0.2V, go to step 4.
- If there is more than 0.2V, check for:
- An open or high resistance in the ground wire.
- Poor ground (G701).
