If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of p1a6b fault code. Here are the symptoms to look out for:

  • The P1A6B fault code in automobiles 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, and difficulty starting the engine.
  • Additionally, the vehicle may experience rough idling or stalling, and there may be a noticeable decrease in acceleration.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle and ensure safe driving conditions.

The P1A6B fault code can be caused by a faulty SGCM, open or shorted harness, or poor electrical connection.

  • The automobile fault code P1A6B can be caused by a faulty Starter/Generator Control Module (SGCM).
  • It can also be caused by an open or shorted Starter/Generator Control Module harness.
  • Additionally, a poor electrical connection in the Starter/Generator Control Module circuit can also trigger this fault code.

To fix the p1a6b automobile fault code, check the possible causes and inspect the wiring harness and connectors for any damage or corrosion.

  • To fix the automobile fault code p1a6b, first, check the possible causes listed above.
  • Then, visually inspect the related wiring harness and connectors.
  • Look for 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 P1A6B has an estimated repair time of 1.0 hour.

The cost of fixing this fault code is influenced by the repair time. Most auto repair shops charge between $75 and $150 per hour for their services.

Therefore, the fixing cost of P1A6B will range between $75 and $150, depending on the repair time required.

The P1A6B fault code is related to the StarterGenerator Control Module. The Accessory Power Module (APM) controls the energy flow between the 42 V DC and 14 V DC buses. The APM power is bi-directional, with negative current representing 14-42 direction, and positive current representing the 42-14 direction.

When the APM Power Conversion direction is set to Off, the APM will not consume or transfer any power. When the APM Power Conversion direction is set to Invalid, the energy will flow from the 42 V DC Bus to the 14 V DC Bus via the APM.

What are the possible causes of the P1A6B fault code in an automobile?

If you see the engine light on or the service engine soon warning light, it could be due to the P1A6B fault code. This code is 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 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 to fix the P1A6B fault code?

If you’re experiencing an Engine Light ON or Service Engine Soon Warning Light due to a P1A6B fault code, it could be caused by a faulty Starter/Generator Control Module (SGCM), an open or shorted SGCM harness, or a poor electrical connection in the SGCM circuit.
