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 consists of the motor, regulator and ECU.

This DTC is stored when the ECU built into the regulator motor 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

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





NG -- CHECK DTC OUTPUT

OK -- 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





B -- READ VALUE USING TECHSTREAM (MULTIPLEX NETWORK MASTER SWITCH)

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

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

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

A -- REPLACE MULTIPLEX NETWORK MASTER SWITCH ASSEMBLY Removal

3. READ VALUE USING TECHSTREAM (MULTIPLEX NETWORK MASTER SWITCH)

(a) Use the Data List to check if the power window regulator motor is functioning properly Scan Tool Testing and Procedures.

D-Door Motor





OK:

On tester screen, each item changes between ON and OFF according to above chart.
