P2C89 Hybrid/EV Battery System Precharge Current Too High
During the HV battery precharge sequence, the inrush current exceeds the calibrated maximum. Indicates short on the DC-link side or insufficient precharge resistance.
Is it safe to drive with P2C89?
The car may go into limp mode (reduced power). Get it diagnosed before a long trip.
Common causes
- Most likelyShort on DC-link (capacitor or load)
- PossiblePrecharge resistor shorted
- Less likelyPack cell imbalance approaching service threshold
Symptoms
- EV/hybrid system warning light on
- Reduced power output or limp mode
- Charging may fail or be slowed
