The P1EF7 code is related to the Battery Charger Control Module. It indicates a problem with the Ignition OnStart Switch Circuit.

The circuit is experiencing high voltage, which can cause issues with the ignition circuit.

This can occur when the vehicle power mode is in Vehicle ON or Vehicle in Service Mode.

The BCM controls the ignition run relay through the control circuit by applying voltage to the circuit. The hybrid powertrain control module 2 sends the vehicle power mode status in a serial data message to various modules, including the battery charger control module.

What are the possible causes of the P1EF7 fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the P1EF7 fault code. This code is usually caused by a faulty Hybrid Powertrain Control Module 2, an open or shorted Hybrid Powertrain Control Module 2 harness, or a poor electrical connection in the Hybrid Powertrain Control Module 2 circuit. To fix this issue, you should visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.

How can I visually inspect the wiring harness and connectors related to the Hybrid Powertrain Control Module 2?
