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

INSPECTION PROCEDURE

Note. DTC B2311 can be stored in each power window regulator motor assembly (power window ECU). If a power window regulator motor assembly has been replaced with a new one, initialize the power window control system. Refer to INITIALIZATION . If a power window regulator motor assembly and door window regulator sub-assembly have been removed and installed, or if a power window regulator motor assembly was reused when a door glass or door glass run was replaced, initialize the power window control system. Refer to INITIALIZATION .

HINT

If DTC B2312 is not output again after the DTC has been cleared, the DTC was output due to the switch being held.

Note. DTC B2312 can be stored in the multiplex network master switch assembly and in each power window regulator motor assembly (power window ECU). If a power window regulator motor assembly has been replaced with a new one, initialize the power window control system. Refer to INITIALIZATION .
