ELECTRONIC SHIFT LEVER SYSTEM, Diagnostic DTC:C2307

DTC Code DTC Name
C2307 Power Supply

DESCRIPTION

The shift control actuator assembly consists of a parking lock motor and rotation angle sensor. The transmission control ECU assembly receives a P position switch signal from the power management control ECU and activates the parking lock motor by controlling current, causing the parking lock mechanism to switch. The transmission control ECU assembly stores this DTC when it detects a malfunction in the parking lock motor system and/or the ground circuit.

DTC No. DTC Detection Condition Trouble Area
C2307 With the power switch on (IG) (IG circuit malfunction is not detected), current of the parking lock motor is 50 A or more or there is an open in the transmission control ECU assembly terminal E01,E02 circuit for 0.1 seconds or more.

  • Transmission control ECU assembly

  • Wire harness or connector

INSPECTION PROCEDURE

Note

It may not be possible to clear the following DTCs using the GTS: DTC C2300 (Actuator System Malfunction), C2301 (Shift Changing Time Malfunction), C2303 (Short in Power Source Relay Circuit), C2304 (Open or Short Circuit in U Phase), C2305 (Open or Short Circuit in V Phase), C2306 (Open or Short Circuit in W Phase), C2307 (Power Supply) and C2309 (Open in B+ Circuit). In such cases, disconnect the P CON MAIN fuse and wait for at least 60 seconds to clear the DTCs after the repair.

PROCEDURE


  1. CHECK HARNESS AND CONNECTOR (TRANSMISSION CONTROL ECU ASSEMBLY - BODY GROUND)


    1. Disconnect the A23 transmission control ECU assembly connector.

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

      Standard Resistance (Check for Open)
      Tester Connection Condition Specified Condition
      A23-6 (E01) - Body ground Power switch off Below 1 Ω
      A23-5 (E02) - Body ground Power switch off Below 1 Ω

    3. Reconnect the A23 transmission control ECU assembly connector.


    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

  2. CHECK HARNESS AND CONNECTOR (TRANSMISSION CONTROL ECU ASSEMBLY - SHIFT CONTROL ACTUATOR ASSEMBLY)


    1. Disconnect the A22 transmission control ECU assembly connector.

    2. Disconnect the D2 shift control actuator assembly connector.

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

      Standard Resistance (Check for Short)
      Tester Connection Condition Specified Condition
      A22-5 (MUA) or D2-1 (MUA) - Body ground and other terminals Power switch off 10 kΩ or higher
      A22-2 (MVA) or D2-6 (MVA) - Body ground and other terminals Power switch off 10 kΩ or higher
      A22-1 (MWA) or D2-7 (MWA) - Body ground and other terminals Power switch off 10 kΩ or higher

    4. Reconnect the D2 shift control actuator assembly connector.

    5. Reconnect the A22 transmission control ECU assembly connector.
