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

INSPECTION PROCEDURE

Note. When the power window regulator motor assembly is reinstalled or replaced, the power window control system must be initialized. After a 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 assembly or power window regulator switch assembly and holding it in the auto up position. Open the power window by fully pushing down the switch.

Note. If DTC B2312 is not output again after the DTC has been cleared, the DTC was output due to the switch being held. When the power window regulator motor assembly is reinstalled or replaced, the power window control system must be initialized. After a 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 assembly or power window regulator switch assembly and holding it at the auto up position. Open the power window by fully pushing down the switch.

Refer to HOW TO PROCEED WITH TROUBLESHOOTING . Troubleshoot the power window control system after confirming that the communication system is functioning properly. When the power window regulator motor assembly (for front passenger side) is reinstalled or replaced, the power window control system must be initialized. After a 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 power window regulator switch assembly (for front passenger side) and holding it at the auto up position. Open the power window by fully pushing down the power window regulator switch assembly (for front passenger side).
