Description
The park / neutral position switch turns on when the shift lever is moved into the r position, causing the back-up lights to illuminate.
Wiring diagram
Inspection procedure
- Inspect fuse (gauge1)
- Remove the gauge1 fuse from the instrument panel junction block.
- Measure the resistance of the fuse.
Standard resistance:
below 1
- Inspect back-up light
- Remove the rear combination light.
- Connect the positive (+) lead from the battery to terminal 6 and the negative (-) lead to terminal 1, then check that the light comes on.
Ok: light comes on.
- Inspect park / neutral position switch
- Disconnect the b26 park / neutral position switch connector.
- Measure the resistance of the switch.
Standard resistance
- check wire harness (park / neutral position switch - battery)
- Disconnect the b26 park / neutral position switch connector.
- Measure the voltage of the wire harness side connector.
Standard voltage
- Check wire harness (park / neutral position switch - back-up light)
- Disconnect the b26 park / neutral position switch connector.
- Disconnect the k12 and k14 rear combination light assembly connectors
- Measure the resistance of the wire harness side connectors.
Standard resistance
Repair or replace harness and connector (back-up light - body ground)
