Self-diagnosis Detection Logic

HINT:
While performing the electrical diagnosis and testing, always refer to the relevant circuit diagram for the 
special circuit and component information.

Diagnosis Procedure

a. Remove the position light bulb, and check if the position light bulb filament is blown.

Use the circuit diagram as a guide to perform the following procedures:
a. Turn ignition switch to LOCK, and disconnect the negative battery cable.
b. Disconnect the Body Control Module (BCM) connectors B-043 and E-072.
c. Disconnect the front right headlight wire harness connector E-034 and rear right combination light wire 

harness connector B-016.

d. Disconnect the body wire harness connector B-048 and engine compartment wire harness connector 



E-070.

e. Check if wire harnesses are worn, pierced, pinched or partially broken.
f. Look for broken, bent, protruded or corroded terminals.
g. Check if the related connector terminal contact pins are in good condition.
