DTC    C2315    HV System

for Preparation Click here


DESCRIPTION

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. When the power management control ECU (HV CPU) detects a malfunction with the P position switch or P position signal, it sends an information signal to the transmission control ECU assembly. After receiving this signal, the transmission control ECU assembly stores this DTC.

DTC No.
