DTC Summary
WARNING: This page is about a different variant/trim than selected.
- MALFUNCTION DESCRIPTION
The hybrid vehicle control ECU monitors the high-voltage wiring between the HV battery and inverter with converter assembly and detects a short circuit malfunction or high-voltage system operation malfunction.
The cause of this malfunction may be one of the following:
Battery current sensor (IB) circuit malfunction
- Battery current sensor (IB) malfunction
- Motor generator control ECU (MG ECU) malfunction
- Communication (wire harness) malfunction
High voltage system malfunction
- HV battery malfunction
- HV battery junction block assembly malfunction
- Inverter with converter assembly malfunction
- Air conditioner system malfunction
- Voltage inverter assembly (w/ 1500W voltage inverter)
- High-voltage wire harness malfunction
- High-voltage connector or connection malfunction
Low-voltage circuit (12 V) malfunction
- Hybrid vehicle control ECU malfunction
- Low voltage wire harness malfunction
- Low voltage connector malfunction
