DTC    C2307    Power Supply

for Preparation Click here


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 (HV CPU) 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 E1 circuit for 0.1 seconds or more.
  1. Transmission control ECU assembly
  2. Wire harness or connector

INSPECTION PROCEDURE

NOTICE:
It may not be possible to clear the following DTCs using the intelligent tester: 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.

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

  1. Disconnect connector A22 from the transmission control ECU assembly.



    C208987E13

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

    Standard Resistance (Check for Open):
    Tester Connection
    		Switch Condition
    		Specified Condition
    A22-6 (E01) - Body ground
    		Power switch off
    		Below 1 Ω
    A22-5 (E02) - Body ground
    		Power switch off
    		Below 1 Ω

REPAIR OR REPLACE HARNESS OR CONNECTOR
OK


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

  1. Disconnect connector A21 from the transmission control ECU assembly.

  1. Disconnect connector D2 from the shift control actuator assembly.



    C210299E14

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

    Standard Resistance (Check for Short):
    Tester Connection
    		Switch Condition
    		Specified Condition
    A21-5 (MUA) or D2-1 (MUA) - Body ground and other terminals
    		Power switch off
    		10 kΩ or higher
    A21-2 (MVA) or D2-6 (MVA) - Body ground and other terminals
    		Power switch off
    		10 kΩ or higher
    A21-1 (MWA) or D2-7 (MWA) - Body ground and other terminals
    		Power switch off
    		10 kΩ or higher
