Diagnosis Procedure

Use the circuit diagram as a guide to perform the following procedures:
a. Turn ignition switch to LOCK.
b. Disconnect the negative battery cable.
c. Disconnect the HVAC control panel assembly connector K-012.
d. Disconnect the left mix damper motor connector K-010 and right mix damper motor connector K-003.
e. Check if wire harnesses are worn, pierced, pinched or partially broken.
f. Look for broken, bent, protruded or corroded terminals.
g. Check if related connector pins are in good condition.

a. Remove the mix damper motor.
b. Install the new mix damper motor to vehicle.
c. Use X-431 3G diagnostic tester to check if DTCs are still output.

a. Turn ignition switch to LOCK.
b. Disconnect the negative battery cable.
c. Disconnect the HVAC control panel assembly connector

K-012.

d. Disconnect the left mix damper motor connector K-010

and right mix damper motor connector K-003.

e. Using a digital multimeter, check for continuity between

terminals of connector K-012 and connector K-010 to
check if there is an open in left mix damper motor
according to the table below.
Standard Condition

f. Using a digital multimeter, check for continuity between

terminals of connector K-012 and connector K-003 to
check if there is an open in right mix damper motor
according to the table below.
