POWER SEAT MANUAL SWITCH CONTINUITY CHECK






POWER LUMBAR SWITCH CONTINUITY CHECK






POWER SEAT MOTOR CHECK









Check the operation of each motor using the following procedure.
1. Disconnect the connector for each motor.
2. Check that each motor runs smoothly when the battery is directly connected to the motor terminals, and that each adjustment mechanism operates in the directions in the table.
3. If there is a problem, replace the power seat adjuster assembly.

LIMIT SWITCH CONTINUITY CHECK









1. Disconnect the limit switch connector and connect a circuit tester to the terminals.
2. Operate the switch and check that there is continuity between the terminals.
3. If there is a problem, replace the power seat adjuster assembly.
