Paddle Shifter - (Downshift Switch) Illumination Circuit Troubleshooting

SRS components are located in this area. Review the SRS component locations (see COMPONENT LOCATION INDEX ) and the precautions and procedures (see PRECAUTIONS AND PROCEDURES ) before doing repair or service.

1. Remove the driver's airbag (see DRIVER'S AIRBAG REPLACEMENT ).
2. Disconnect the paddle shifter - (downshift switch) 4P connector.
3. Turn the lighting switch ON.
4. Measure the voltage between paddle shifter - (downshift switch) 4P connector terminal No. 4 and body ground.

   Is there battery voltage? 

   YES  -Go to step  8.

   NO  -Go to step  5.

5. Turn the lighting switch OFF.
6. Check for blown No. B29 (10A) fuse in the under-dash fuse/relay box.

   Is the fuse OK? 

   YES  -Repair an open in the wire between paddle shifter - (downshift switch) 4P connector terminal No. 4 and the under-dash fuse/relay box.

   NO  -Go to step  7.

7. Check for continuity between paddle shifter - (downshift switch) 4P connector terminal No. 4 and body ground.

   Is there continuity? 

   YES  -Repair a short in the wire between paddle shifter - (downshift switch) 4P connector terminal No. 4 and the under-dash fuse/relay box.

   NO  -Go to step  9.

8. Turn the lighting switch OFF.
9. Check for continuity between paddle shifter - (downshift switch) 4P connector terminal No. 3 and body ground.

   Is there continuity? 

   YES  -Repair a short in the wire between paddle shifter - (downshift switch) 4P connector terminal No. 3 and the gauge control module.

   NO  -Go to step  10.

10. Disconnect the gauge control module 32P connector.
11. Check for continuity between paddle shifter - (downshift switch) 4P connector terminal No. 3 and gauge control module 32P connector terminal No. 16.

    Is there continuity? 

    YES  -Check the illumination control circuit in the gauge control module self-diagnostic function (see SELF-DIAGNOSTIC FUNCTION ). If the test results are OK, replace the paddle shifter - (downshift switch) (see PADDLE SHIFTER + (UPSHIFT SWITCH) OR PADDLE SHIFTER - (DOWNSHIFT SWITCH) REPLACEMENT  ).

    NO  -Repair an open in the wire between paddle shifter - (downshift switch) 4P connector terminal No. 3 and the gauge control module.
