Glass Position Initialization Incomplete (B2313)

DESCRIPTION

The power window regulator motor assembly is operated by the power window regulator master switch assembly or power window regulator switch assembly. The power window regulator motor assembly has motor, regulator and ECU functions.

When the ECU determines that the power window regulator motor assembly has not been initialized, DTC B2313 is set.

HINT:

DTC B2313 can be stored in each power window regulator motor assembly (power window ECU).

CAUTION / NOTICE / HINT

NOTICE:

• When the power window regulator motor assembly is reinstalled or replaced, the power window control system must be initialized.
• After a 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 reinitialized by repeating the following operations at least 5 times:
  1. Close the power window by fully pulling up the power window regulator master switch assembly or power window regulator switch assembly and holding it at the auto up position.
  2. Open the power window by fully pushing down the switch.

PROCEDURE

1. PERFORM INITIALIZATION (APPLICABLE LOCATION)

(a) Turn the ignition switch to ON.

(b) Initialize the power window regulator motor assembly (See page ).

HINT:

Initialize the power window regulator motor assembly that has DTC B2313 stored in its ECU.

NEXT

1. CHECK DTC OUTPUT

(a) Turn the ignition switch off.

(b) Wait for at least 10 seconds, and then turn the ignition switch to ON.

(c) Check for DTCs (See page ).

HINT:

Check for DTCs for the power window regulator motor assembly that has DTC B2313 stored in its ECU.

OK:

B2313 output does not recur.
