Backup Lamp Switch: Testing and Inspection

Back-up Light Switch Test

1. Disconnect the back-up light switch 2P connector (A).






2. Check for continuity between back-up light switch 2P connector terminals No. 1 and No. 2. There should be continuity only when the shift lever is in reverse.
- If the test result is OK, go to step 5.

- If the test result is faulty, go to step 3.





3. Remove the back-up light switch (A). Check for continuity between back-up light switch 2P connector terminals No. 1 and No. 2. There should be continuity when the actuator (B) is pressed, and no continuity when the actuator is released.
- If the test result is OK, check the reverse shift mechanism in the transmission.

- If the test result is faulty, replace the back-up light switch.

4. Apply liquid gasket (P/N 08717-0004, 08718-0001, 08718-0012, 08718-0003, or 08718-0009) to the threads of the back-up light switch, and install it on the transmission housing.
