Backup Lamp: Testing and Inspection

Manual Transmission:
1. If only one back-up light does not go ON, check that bulb in the taillight.
2. If neither back-up light goes ON, check the No. 5 (15 A) fuse in the under-clash fuse box.

Back-up Lights Test:

3. If the fuse and bulbs are OK, disconnect the connector from the back-up light switch on the transmission housing.
4. Check for continuity between the A (YEL) and B (GRN/BLK) wires with the switch installed. There should be continuity with the shift lever in reverse.
- If there is no continuity, replace the switch.
- If there is continuity, but the back-up lights do not go on, check for:
- Poor ground (G551).
- An open in the YEL or GRN/BLK wire.

Automatic Transmission:
1. If only one back-up light does not go ON, check that bulb in the taillight.
2. If neither back-up light goes ON, check the No. 5 (15 A) fuse in the under-dash fuse box.

Back-up Lights Test:

3. If the fuse and bulbs are OK, disconnect the 12P connector from the A/T gear position switch (back-up light switch).
4. Check for continuity between the No. 9 and No. 10 terminals. Move the lever back and forth at the [R] position without touching the push button, and check for continuity within the range of free play.
- If there is no continuity within the range of free play, adjust the position of the A/T gear position switch (see A/T gear position switch test).
- If there is continuity, but the back-up lights do not go ON, check for:
- Poor ground (G551).
- An open in the YEL or GRN/BLK wire.
