DTC P1C2D-62: Hybrid/EV Battery "A" Voltage Sensor/Boosting Converter Voltage Sensor "A" Signal Compare Failure [12/2019 - 11/2023]: Description

WARNING: This page is about a different variant/trim than selected.

For a description of the boost converter.

Refer to DESCRIPTION

The MG ECU uses a voltage sensor (VL) that is built into the boost converter to detect the high voltage before it is boosted. The ECU also uses the battery voltage sensor to detect HV battery voltage (VB).

DTC No. Detection Item DTC Detection Condition Trouble Area MIL Warning Indicate
P1C2D-62 Hybrid/EV Battery "A" Voltage Sensor/Boosting Converter Voltage Sensor "A" Signal Compare Failure Voltages from HV battery voltage (VB) sensor and boost converter voltage (VL) sensor deviate:
Difference between "VL-Voltage before Boosting" and "Hybrid Battery Voltage" is large when the boosting request is given.
