B2313

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

DTC B2313 - Glass Position Initialization Incomplete

DESCRIPTION

The portion of the power window control system that is located in the driver door consists of a power window master switch, regulator, and a motor with an integrated ECU. The driver door power window regulator motor is controlled by the ECU when the power window master switch is operated (models with jam protection).
When the ECU determines that the driver's door 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. Initialization





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 ignition switch off.
(b) Wait for at least 10 seconds, and then turn the ignition switch on (IG).
(c) Check whether the DTC output recurs.
Result:






A -- USE SIMULATION METHOD TO CHECK
B -- Continue to next step.
2. INITIALIZE SYSTEM (POWER WINDOW CONTROL SYSTEM)
(a) Turn the ignition switch on (IG) and initialize the power window regulator motor (on the driver side) Initialization.
(b) Turn the ignition switch off.
(c) Wait for at least 10 seconds, and then turn the ignition switch on (IG).
(d) Check whether the DTC output recurs.
Result:






B -- END
A -- REPLACE POWER WINDOW REGULATOR MOTOR ASSEMBLY (for Driver Side)
