The P0AE5 fault code refers to the Hybrid Battery Precharge Contactor Control Circuit RangePerformance.

This code is related to the operation of the System Main Relays (SMRs) in the high-voltage power supply circuit. The SMRs consist of three relays, with one for the negative side and two for the positive side. They are responsible for connecting and disconnecting the high-voltage power supply circuit as requested by the HV control ECU.

During the connection process, SMR1 and SMR3 turn on initially, followed by SMR2. This sequence helps protect 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 checks that the relays have turned off properly to ensure proper operation.

The P0AE5 fault code indicates that there may be a malfunction in the Hybrid Battery Precharge Contactor Control Circuit.

It is important to address this issue promptly to maintain the reliable operation of the high-voltage power supply circuit.

What are the possible causes for the automobile fault code p0ae5?

If you see the engine light or service engine soon warning light on, the fault code P0AE5 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 p0ae5 fault code?

If you’re dealing with the p0ae5 fault code and your engine light is on, it’s time to take a closer look at the wiring harness and connectors. The possible causes include 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, visually inspect the wiring harness and connectors for any signs of damage. Pay attention to broken, bent, pushed out, or corroded pins on the connectors. This step will help you identify and address any issues with the electrical components.

What should I look for when checking for damaged components or corroded connector pins to resolve the p0ae5 fault code?

When resolving the p0ae5 fault code, start by checking for damaged components or corroded connector pins. This can be done by visually inspecting the related wiring harness and connectors. Look for any broken, bent, pushed out, or corroded pins. These issues can cause a poor electrical connection or an open/short circuit, leading to the engine light being on. By addressing these possible causes, you can effectively fix the problem.
