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 turn signal light bulb, and check if the turn signal 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 left turn signal light wire harness connectors F-005, E-056 and B-021.
d. Disconnect the body wire harness connectors B-048 and B-041, front left door wire harness connector
F-007 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.

BCM connector E-072 to check if it is short to power
supply according to the table below.
Standard Condition
e. Using a digital multimeter, check for continuity between
