Backup Lamp: Testing and Inspection

NOTE: Check the No.1 (10 A) fuse in the under-dash fusel relay box before testing.

1. Test the back-up light switch by shifting the shift lever to [R] and turning the ignition switch ON (II).
2. If the back-up lights do not go on, check the back-up light bulbs in the taillight assembly.

Test:

3. If the fuse and bulbs are OK, disconnect the 14P connector from the A/T gear position switch (back-up light switch).
4. Check for continuity between the No. 12 and No. 14 terminals. Move the lever back and forth at the [R] position without pushing down on the lever, and check for continuity within the range of free play of the shift lever.
^ If there is no continuity within the range of free play, adjust the A/T gear position switch.
^ If there is continuity, but the back-up lights do not go on, check for:
- Poor ground (G502)
- An open in the YEL or GRN/BLK wire
