The P0AE6 fault code refers to a problem with the Hybrid Battery Precharge Contactor Control Circuit. This circuit is responsible for controlling the precharging of the hybrid battery in a vehicle.

The SMRs (System Main Relays) play a crucial role in connecting and disconnecting the high-voltage power supply circuit as per the requests from the HV control ECU. There are a total of 3 relays, with 1 for the negative side and 2 for the positive side.

During the connection process, SMR1 and SMR3 initially turn ON, followed by SMR2.

This sequential activation helps protect the circuit from high-voltage surge current by allowing the limit current to flow through a resistor.

When it comes to disconnection, SMR2 and SMR3 turn OFF in a specific order.

The HV control ECU ensures that the relays have turned OFF properly to maintain proper operation. The P0AE6 fault code indicates that there is a low voltage issue in the Hybrid Battery Precharge Contactor Control Circuit. This could be due to a malfunction in the SMRs (CON1, CON2, and CON3) that the HV control ECU monitors.

What are the possible causes for the automobile fault code p0ae6?

If you see the engine light or service engine soon warning light on, the fault code P0AE6 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 p0ae6 fault code?

If you’re dealing with the p0ae6 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 and connector’s pins to resolve the p0ae6 fault code?

When resolving the p0ae6 fault code, start by checking for damaged components and connector’s pins. This can be done by visually inspecting the related wiring harness and connectors. Look for any signs of damage such as broken, bent, pushed out, or corroded pins. By doing this, you can identify any issues that may be causing the fault code and take the necessary steps to fix them.
