The P0AE1 fault code refers to a potential issue with the Hybrid Battery Precharge Contactor Circuit. This circuit is responsible for connecting and disconnecting the high-voltage power supply in the hybrid vehicle. The circuit consists of three relays, with two on the positive side and one on the negative side.

When connecting, SMR1 and SMR3 turn on initially, followed by SMR2. This process protects the circuit from high-voltage surge current by allowing the limit current to flow through a resistor.

When disconnecting, SMR2 and SMR3 turn off in that order.

The HV control ECU monitors the proper operation of the SMRs (CON1, CON2, and CON3) to check for any malfunctions. If the P0AE1 fault code is detected, it indicates a potential issue with the Hybrid Battery Precharge Contactor Circuit.

It is important to have this issue diagnosed and repaired by a qualified technician to ensure the proper functioning of the high-voltage power supply in the hybrid vehicle.

What are the possible causes for the automobile fault code P0AE1?

If you see the engine light or service engine soon warning light on, the fault code P0AE1 could be the culprit. This code is often caused by a faulty system main relay, an open or shorted relay harness, a poor electrical connection in the relay circuit, or a faulty HV control ECU. To fix the issue, start by visually inspecting the wiring harness and connectors. Look for any damaged components and check for broken, bent, pushed out, or corroded connector pins. Don’t forget to check the possible causes mentioned above.

How can I visually inspect the wiring harness and connectors to fix the P0AE1 fault code?
