POWER WINDOW CONTROL SYSTEM, Diagnostic DTC:B2313, B2316

DTC Code DTC Name
B2313 Driver Side Glass Position Initialization Incomplete
B2316 Passenger Side Glass Position Initialization Incomplete

DESCRIPTION

The power window regulator motor assembly (driver side or front passenger side) is operated by the power window regulator master switch assembly or the power window regulator switch assembly. When the ECU (power window regulator master switch assembly) determines that the power window regulator master switch assembly or the power window regulator switch assembly has not been initialized, or the pulse output circuit of the power window regulator motor assembly (driver side or front passenger side) is abnormal, DTC B2313 or B2316 is stored.

  4. CHECK HARNESS AND CONNECTOR (POWER WINDOW REGULATOR MASTER SWITCH ASSEMBLY - POWER WINDOW REGULATOR MOTOR ASSEMBLY (FOR DRIVER SIDE))


    1. Disconnect the E8*1 or F6*2 power window regulator master switch assembly connector.

    2. Disconnect the E5*1 or F1*2 power window regulator motor assembly (for driver side) connector.

    3. Measure the resistance according to the value(s) in the table below.

      Standard Resistance (Check for Open)
      Tester Connection Condition Specified Condition
      E8-8 (SN1) - E5-6 (SN1)*1 Always Below 1 Ω
