The P1AE4 code is related to the high voltage interlock circuit in an automobile. This circuit is used to verify the integrity of high voltage components. It passes through certain high voltage components and detects any attempt to access them.

The battery energy control module sources current on the 5V high voltage interlock circuit loop.

Both motor control modules monitor the circuit for current to detect an open condition.

If a fault is detected, the high voltage contactor relays are commanded open by the hybrid powertrain control module.

What are the possible causes of the P1AE4 fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the P1AE4 fault code. This code is usually caused by a faulty drive motor generator power inverter module, an open or shorted harness, or a poor electrical connection in the 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.
