Power Window Switch Malfunction





WINDOW / GLASS: POWER WINDOW CONTROL SYSTEM: B2312: Power Window Switch Malfunction
B2312 - Power Window Switch Malfunction

DESCRIPTION

The power window regulator motor is driven by operating the power window regulator switch. The power window regulator motor assembly consists of the motor and ECU.

This DTC is output when the ECU built into the regulator motor and master switch determines that the multiplex network master switch assembly or power window regulator switch assembly is stuck.

HINT
This DTC may be stored for all the windows.

NOTICE:
* When a power window regulator 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 resumed by repeating the following operation at least 5 times:
(1) Close the power window by fully pulling up the power window switch and holding it in the auto up position.
(2) Open the power window by fully pushing down the power window switch.

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.

PROCEDURE

1. CHECK FOR DTC

(a) Clear the DTC Reading and Clearing Diagnostic Trouble Codes.

(b) Check for DTCs Reading and Clearing Diagnostic Trouble Codes.

Result





C -- CHECK DTC OUTPUT

B -- GO TO LIN COMMUNICATION SYSTEM Initial Inspection and Diagnostic Overview

A -- END (DTC WAS STORED DUE TO SWITCH BEING OPERATED FOR 20 SECONDS OR MORE)

2. CHECK DTC OUTPUT

(a) Check the parts which the DTCs have been output from.

Result





E -- READ VALUE USING TECHSTREAM (REAR POWER WINDOW REGULATOR SWITCH RH)

D -- READ VALUE USING TECHSTREAM (REAR POWER WINDOW REGULATOR SWITCH LH)
