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)
