B2313

WINDSHIELD / WINDOWGLASS: POWER WINDOW CONTROL SYSTEM: B2313: Glass Position Initialization Incomplete

DTC B2313 - Glass Position Initialization Incomplete

DESCRIPTION

The power window control system that is located in each door consists of a power window master switch, power window switches, regulators, and motors with an integrated ECU. A power window regulator motor is controlled by the ECU when the power window switch is operated (models with jam protection).
When only of the ECUs determines that the power window regulator motor assembly has not been initialized, DTC B2313 is set.
NOTE:
The power window control system uses a serial communication protocol (LIN) to communicate with the main body ECU. Inspect the communication function by following HOW TO PROCEED WITH TROUBLESHOOTING. Troubleshoot the power window control system after confirming that the communication system is functioning properly.
HINT:
- Replacing the door glass or door glass run may cause a difference to exist between the current door glass position and the position memorized in the ECU. In this case, the jam protection function may work improperly. Return the system to the pre-initialized condition and reinitialize the system.
- To return the system to the pre-initialized condition:
Disconnect the power window regulator motor connector during power window operation. This will return the motor to the pre-initialized condition.





INSPECTION PROCEDURE
NOTE:
When using Techstream to troubleshoot the LIN communication line: Connect Techstream to the vehicle, and turn the courtesy light switch on and off at 1.5 second intervals until communication between the tester and vehicle begins.

PROCEDURE

1. CHECK DTC OUTPUT
(a) Turn the engine switch off.
(b) Wait for at least 10 seconds, and then turn the engine switch on (IG).
(c) Check whether the DTC output recurs.
Result:






B -- END
A -- Continue to next step.
2. INITIALIZE SYSTEM (POWER WINDOW CONTROL SYSTEM)
(a) Turn the engine switch on (IG) and initialize the power window regulator motor Programming and Relearning.
(b) Turn the engine switch off.
(c) Wait for at least 10 seconds, and then turn the engine switch on (IG).
(d) Check whether the DTC output recurs.
Result:






B -- REPLACE POWER WINDOW REGULATOR MOTOR ASSEMBLY
A -- END
