2. INSPECT REAR COMBINATION LIGHT ASSEMBLY (STOP LIGHT)





(a) Remove the rear combination light.

(b) Apply battery voltage to the rear combination light connector and check that the stop light illuminates.

OK:





NG -- REPLACE REAR COMBINATION LIGHT ASSEMBLY
OK -- Continue to next step.

3. CHECK WIRE HARNESS (ECU - BATTERY AND BODY GROUND)





(a) Disconnect the 6L junction block connector.

(b) Measure the voltage of the wire harness side connectors.

Standard voltage:





NG -- REPAIR OR REPLACE HARNESS AND CONNECTOR
OK -- Continue to next step.

4. CHECK WIRE HARNESS (LIGHT - ECU AND BODY GROUND)
