  • If you experience any of these symptoms, it is important to have your vehicle diagnosed and repaired by a qualified mechanic as soon as possible to prevent further damage.

The P1AAF automobile fault code can be caused by various factors, including a faulty SGCM or poor electrical connection.

  • The automobile fault code P1AAF can be caused by a faulty Starter/Generator Control Module (SGCM).
  • It can also be caused by an open or shorted SGCM harness.
  • Additionally, a poor electrical connection in the SGCM circuit can also trigger this fault code.

Below are the possible fixes for the automobile fault code p1aaf, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code P1AAF, 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 fault code P1AAF is related to the hybrid powertrain system.

The diagnosis cost may vary depending on the auto repair shop and the equipment used. The estimated repair time for this fault code is 1.0 hour.

The fixing cost may range from $75 to $150 per hour, depending on the location and the expertise of the mechanic.

It is important to get the fault code diagnosed and fixed as soon as possible to avoid further damage to the vehicle and to ensure its optimal performance.

The P1AAF fault code is related to the StarterGenerator Control Module (SGCM) unit in a vehicle.

The SGCM unit performs DCDC and DCAC electrical energy conversion and supports vehicle functions. The fault code indicates an issue with the StarterGenerator Phase U-V-W Circu, which is responsible for monitoring and generating 3-phase AC power to the Starter Generator interface.

If the Starter Generator Speed and Torque values are zero, the Starter Generator Control will be disabled, and the Starter Generator Inverter will not transfer or consume any power. The 3-Phase AC Current is defined as the current value of Phase 1, which can be bidirectional, with positive representing discharging the batteries and negative representing charging the batteries.

What are the possible causes of the P1AAF fault code in an automobile?

If you see the engine light on or the service engine soon warning light in your automobile, it could be due to the P1AAF fault code. This code is usually caused by a faulty Starter/Generator Control Module (SGCM), an open or shorted SGCM harness, or a poor electrical connection in the SGCM 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.

How can one visually inspect the wiring harness and connectors related to the Starter/Generator Control Module (SGCM)?

If the engine light is on due to a faulty Starter/Generator Control Module (SGCM), it is important to visually inspect the related wiring harness and connectors. This can be done by checking for damaged components and looking for broken, bent, pushed out, or corroded connector’s pins. It is also important to check for an open or shorted SGCM harness and poor electrical connections. By doing so, you can identify the root cause of the problem and take the necessary steps to fix it.

What are the consequences of ignoring the P1AAF fault code in an automobile?

Ignoring the P1AAF fault code in an automobile, which indicates a faulty Starter/Generator Control Module (SGCM), can lead to serious consequences. The engine light will remain on, and the vehicle may not start or may stall while driving. It is crucial to inspect the related wiring harness and connectors and check for damaged components to avoid further damage.
