Normal Operation

When the ignition is turned on the Battery Control Module (BCM) makes various vehicle checks. If these checks are normal~ the BCM sends a signal to the contactor to close~ which will supply high-voltage power to the vehicle. If a precharge contactor overcurrent condition is sensed by the BCM the stop safely hazard (red triangle) warning indicator is illuminated and the vehicle will shut down and/or not start.

This DTC can set as a result of a discharged 12-volt battery~ a fault on the DC/DC converter enable circuit a fault on the high-voltage bus the Electronically Controlled Continuously Variable Transmission (eCVT) or the high-voltage wiring.

^ DTC POAE1 (Hybrid Battery Precharge Contactor Circuit) If the precharge contactor attempts to close and current flow exceeds set values DTC POAE1 will set. This could indicate a short in the high-voltage system.

Possible Causes:

^ High-voltage cable assembly
^ BCM
^ High Voltage Traction Battery (HVTB)
^ eCVT
