Head Rest: Testing and Inspection

Front seat:
INSPECT HEADREST MOTOR OPERATION
a. Connect the positive (+) lead from the battery to terminal 1, and the negative (-) lead to terminal 5, and check that the motor turns counterclockwise.
b. Reverse the polarity, and check that the motor turns clockwise.
If operation is not as specified, replace the motor.




Front seat:
INSPECT HEADREST MOTOR CIRCUIT BREAKER OPERATION
a. Connect the positive (+) lead from the battery to terminal 1 and the negative (-) lead to terminal 5 on the motor connector and move the headrest to DOWN position.




b. Continue to apply voltage, check that there is a circuit breaker operation noise within 4 to 60 seconds.
c. Reverse the polarity check that the headrest begins to move UP side within approx. 60 seconds.
If operation is not as specified, replace the motor.




Rear seat:
INSPECT HEADREST MOTOR OPERATION
a. Connect the positive (+) lead from the battery to terminal 1, and the negative (-) lead to terminal 5, and check that the motor turns counterclockwise.
b. Reverse the polarity, and check that the motor turns clockwise.
If operation is not as specified, replace the motor.

INSPECT REAR SEAT HEADREST LIMIT SWITCH
Measure the resistance between terminals.
If resistance value is not as specified, replace the vibrator assembly.
