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 hybrid vehicle control ECU assembly 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. Detection Item DTC Detection Condition Trouble Area Warning Indicate Memory
C2307 Power Supply 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 and E02 circuits for 0.1 seconds or more.

CAUTION / NOTICE / HINT

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 A132 transmission control ECU assembly connector.
