The P1AB2 fault code can be caused by a faulty SGCM, open or shorted harness, or poor electrical connection.

  • The automobile fault code P1AB2 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.

Below are some possible fixes for the automobile fault code p1ab2, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code p1ab2, 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 fault code P1AB2 is a diagnostic trouble code related to the hybrid battery pack.

The code indicates that there is an issue with the battery pack’s cooling system. The estimated repair time for this issue 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.

The P1AB2 fault code relates to the Hybrid System Voltage.

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 P1AB2 fault code and how can they be identified?

If you see the engine light on or service engine soon warning light, it could be due to the P1AB2 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 identify the cause, visually inspect the wiring harness and connectors for any damage or corrosion. Check for broken, bent, pushed out, or corroded connector pins.

How can a faulty Starter/Generator Control Module (SGCM) be fixed when it triggers the P1AB2 fault code?

If your engine light is on and the P1AB2 fault code is triggered, it may be due to a faulty Starter/Generator Control Module (SGCM). To fix this issue, you should visually inspect the related wiring harness and connectors, checking for damaged components and looking for broken, bent, pushed out, or corroded connector’s pins. Additionally, check for poor electrical connections and ensure that the SGCM harness is not open or shorted.

What steps should be taken to visually inspect the wiring harness and connectors when troubleshooting the P1AB2 fault code?

When troubleshooting the P1AB2 fault code, start by checking the possible causes, which include a faulty SGCM, an open or shorted SGCM harness, or a poor electrical connection in the SGCM circuit. To visually inspect the related wiring harness and connectors, look for damaged components and check for broken, bent, pushed out, or corroded connector pins.
