Power Window Control System (Diagnostic Codes & Symptom Tests): Diagnosis Scion tC II рестайлинг

INSPECTION PROCEDURE

Note. When a power window regulator motor assembly LH 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 power window regulator master switch assembly and holding it in the auto up position. Open the power window by fully pushing down the power window regulator master switch assembly. Inspect the fuses for circuits related to this system before performing the following inspection procedure.

HINT

Since the power window control system has functions that use LIN communication, first confirm that there is no malfunction in the communication system by inspecting the LIN communication functions in accordance with the "How to Proceed with Troubleshooting" procedures. Then, conduct the following inspection procedure.
