INSEPCTION PROCEDURE

PROCEDURE

1. PERFORM ACTIVE TEST USING TECHSTREAM (TAILLIGHT)

(a) Select the ACTIVE TEST, use the Techstream to generate a control command, and then check that the taillight illuminates.

Body No. 4





OK:

Taillight illuminates.

OK -- PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN PROBLEM SYMPTOMS TABLE
NG -- Continue to next step.

2. INSPECT REAR COMBINATION LIGHT ASSEMBLY (TAILLIGHT)





(a) Remove the rear combination light.

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

OK:





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

3. CHECK WIRE HARNESS (ECU - BATTERY)





(a) Disconnect the 6L junction block connector.

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

Standard voltage:





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

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





(a) Disconnect the R6*1 or R7*2 light connector.

HINT
*1: LH

*2: RH

(b) Disconnect the L24 ECU connector.

(c) Measure the resistance of the wire harness side connectors.

Standard resistance:

LH
RH










NG -- REPAIR OR REPLACE HARNESS AND CONNECTOR

OK -- PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN PROBLEM SYMPTOMS TABLE
