Power Window Control System (Diagnostic Codes & Symptom Tests): Diagnosis

INSPECTION PROCEDURE

Note. When a power window regulator motor is reinstalled or replaced, the power window control system must be initialized. After any door glass or a door glass run has been replaced, the jam protection function may operate unexpectedly when the auto up function is used. In such cases, the auto up function can be reinitialized by repeating the following operations at least 5 times: Close the power window by fully pulling up the multiplex network master switch or power window regulator switch and holding it in the auto up position. Open the power window by fully pushing down the switch.

After any door glass or a door glass run has been replaced, the jam protection function may operate unexpectedly when the auto up function is used. In such cases, the auto up function can be reinitialized by repeating the following operations at least 5 times: Close the power window by fully pulling up the multiplex network master switch or back door power window regulator switch and holding it in the auto up position. Open the power window by fully pushing down the switch.

HINT

Note. When a power window regulator motor is reinstalled or replaced, the power window control system must be initialized. After any door glass or a door glass run has been replaced, the jam protection function may operate unexpectedly when the auto up function is used. In such cases, the auto up function can be reinitialized by repeating the following operations at least 5 times: Close the power window by fully pulling up the multiplex network master switch or power window regulator switch and holding it at the auto up position. Open the power window by fully pushing down the multiplex network master switch or power window regulator switch.
