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 left headlight wire harness connector E-056 and rear left combination light wire
harness connector B-021.
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.
