ELECTRONIC SHIFT LEVER SYSTEM, Diagnostic DTC:C2307

DTC Code DTC Name
C2307 Power Supply

DESCRIPTION

The shift control actuator consists of the parking lock motor and the rotation angle sensor. The transmission control ECU receives a P position switch signal from the power management control ECU (HV CPU) and activates the parking lock motor by controlling current, causing the parking lock mechanism to switch. The transmission control ECU 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 terminal E1 circuit for 0.1 seconds or more.

  • Transmission control ECU assembly

  • Wire harness or connector

INSPECTION PROCEDURE

Note

It is not possible to clear the following DTCs using the intelligent tester: DTCs 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). After the repair, it is necessary to disconnect the P CON MAIN fuse and wait for at least 60 seconds to clear the DTCs.

PROCEDURE


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


    1. Disconnect connector A97 from the transmission control ECU assembly.

      A97-1 (E1) - Body ground Power switch off Below 1 Ω

    3. Connect the 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)


    1. Disconnect connector A96 from the transmission control ECU assembly.

    2. Disconnect connector B130 from the shift control actuator assembly.

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

      Standard Resistance (Check for Short)
      Tester Connection Switch Condition Specified Condition
      A96-5 (MUA) or B130-1 (MUA) - Body ground and other terminals Power switch off 10 kΩ or higher
      A96-2 (MVA) or B130-6 (MVA) - Body ground and other terminals Power switch off 10 kΩ or higher
      A96-1 (MWA) or B130-7 (MWA) - Body ground and other terminals Power switch off 10 kΩ or higher

    4. Connect the shift control actuator assembly connector.

    5. Connect the transmission control ECU assembly connector.
