Backup Lamp Switch: Testing and Inspection

NOTE: Check the No. 13 (15 A) fuse in the under-dash fuse/relay box before testing.

1. Test the back-up light switch by moving the shift lever to reverse 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.




3. If the fuse and bulbs are OK, disconnect the connectors from the back-up light switch.




4. Check for continuity between the terminals in each switch position according to the table.
^ If there is no continuity, replace the back-up light switch.
^ If there is continuity, but the back-up lights do not go on, check for:
- poor ground (G601).
- an open in the YEL or GRN/BLK wire.
