[SOLVED] Fixing P1A93 Code: 14-Volt Power Module Stuck Off

The P1A93 automobile fault code indicates a problem with the StarterGenerator Control Module (SGCM) in the vehicle. This can cause the engine light to turn on, indicating a need for service. The cause of this issue could be a faulty SGCM, an open or shorted SGCM harness, or a poor electrical connection in the SGCM circuit.

It is important to visually inspect the wiring harness and connectors for any damage or corrosion.

The repair time for this issue is estimated to be around 1.0, and it is crucial to address this problem promptly to avoid further damage to the vehicle.

To interpret the fault code, it is recommended to check the “Possible Causes” listed above and inspect the related components thoroughly.

If you notice the Engine Light ON (or Service Engine Soon Warning Light), it could be a sign of p1a93 fault code. Here are the symptoms to look out for:

  • The P1A93 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, and difficulty starting the engine.
  • Additionally, the vehicle may experience stalling or hesitation during acceleration, and the battery may fail to charge properly.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle and ensure safe operation on the road.

The P1A93 fault code in automobiles can be caused by various factors, including a faulty SGCM or poor electrical connection.

  • The automobile fault code P1A93 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.

To fix the p1a93 automobile fault code, check the possible causes and inspect related components for damage or corrosion.

  • To fix the automobile fault code P1A93, 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 P1A93 indicates an issue with the hybrid battery system. The estimated repair time for this fault code is 1.0 hour. The cost of fixing this issue can vary depending on the auto repair shop, but it is common for most shops to charge between $75 and $150 per hour.

Other factors that may influence the cost include the severity of the issue, the type of vehicle, and the location of the repair shop. It is important to address this fault code promptly to avoid further damage to the hybrid battery system.

The P1A93 fault code indicates that the 14-Volt Power Module is stuck OFF. The Accessory Power Module (APM) controls the energy flow between the 42 V DC and 14 V DC buses.

The APM power is bidirectional, 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. The P1A93 fault code may cause issues with the Service Charge or jump start.

What are the possible causes of the P1A93 automobile fault code?

The P1A93 fault code in automobiles is indicated by the engine light turning on. It is caused by a faulty Starter/Generator Control Module (SGCM), an open or shorted SGCM harness, or poor electrical connection in the SGCM circuit. To fix this issue, one must 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 wiring harness and connectors related to the Starter/Generator Control Module (SGCM)?

If you’re experiencing an Engine Light ON or Service Engine Soon Warning Light, it could be due to 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, visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. This will help you identify the problem and take the necessary steps to resolve it.

What are the steps to take if I find damaged components or broken, bent, pushed out, or corroded connector’s pins while inspecting the wiring harness and connectors?
