If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of p1ae5 fault code. Here are the symptoms to look out for:

  • The P1AE5 fault code in an automobile can cause several symptoms, including the engine light turning on or the service engine soon warning light appearing.
  • Other symptoms may include reduced engine power, decreased fuel efficiency, rough idling, stalling, and difficulty starting the engine.
  • Additionally, the vehicle may experience a decrease in acceleration or a loss of power while driving.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle and ensure safe driving conditions.

The P1AE5 fault code can be caused by a faulty control module, open harness, or poor electrical connection.

  • The automobile fault code P1AE5 can be caused by a faulty Drive Motor Generator Battery Control Module.
  • It can also be caused by an open or shorted Drive Motor Generator Battery Control Module harness.
  • Additionally, a poor electrical connection in the Drive Motor Generator Battery Control Module circuit can also trigger this fault code.

Below are the possible fixes for the automobile fault code p1ae5, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code P1AE5, first, check the possible causes listed above.
  • Then, visually inspect the related wiring harness and connectors.
  • Look for any damaged components and check for broken, bent, pushed out, or corroded connector’s pins.
  • This fix will take an estimated repair time of 1.0 hour.

The automobile fault code P1AE5 has an estimated repair time of 1.0 hour.

The cost of fixing this fault code varies depending on the auto repair shop, but it is common for most shops to charge between $75 and $150 per hour. These factors, along with the specific symptoms and causes of the fault code, will determine the overall cost of diagnosis and repair.

The P1AE5 code refers to a fault in the Battery Energy Control Module (BECM). The BECM diagnoses its own systems and detects when a fault condition is present.

The hybrid powertrain control module (HPCM) receives diagnostic and system status information from the BECM through serial data. The BECM uses a pulse width modulated (PWM) signal from the HPCM to open and close high voltage contactors. The P1AE5 code specifically indicates a problem with the Hybrid Battery Power Off Control Circuit.

What are the possible causes of the P1AE5 automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the P1AE5 fault code. This code is caused by a faulty drive motor generator battery control module, an open or shorted harness, or poor electrical connection in the control module circuit. To fix this issue, you should visually inspect the 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 related wiring harness and connectors to fix the P1AE5 fault code?

If you’re experiencing the P1AE5 fault code, which is indicated by the engine light or service engine soon warning light being on, there are a few things you can do to fix it. The cause of this issue could be a faulty drive motor generator battery control module, an open or shorted harness, or a poor electrical connection.
