[SOLVED] P1A98 Code: High Voltage In Hybrid Battery – How To Fix

If you see the engine light on or the service engine soon warning light, it could be due to a fault code P1A98. This code indicates a problem with the StarterGenerator Control Module (SGCM) or its circuit. The SGCM may be faulty, or its harness may be open or shorted, or there may be a poor electrical connection.

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

The repair time for this fault code is 1.0, and it is crucial to fix it as soon as possible to avoid further damage to the vehicle. To interpret the fault code, you need an OBD-II scanner that can read the code and provide a description of the problem.

If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of p1a98 fault code. Here are the symptoms to look out for:

  • The P1A98 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 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 P1A98 fault code in automobiles can be caused by various factors, including a faulty SGCM or poor electrical connection.

  • The automobile fault code P1A98 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 p1a98 automobile fault code, check the possible causes and inspect related wiring harness and connectors for damage.

  • To fix the automobile fault code p1a98, 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 factors that influence the cost of diagnosing and fixing the automobile fault code P1A98 are: – The estimated repair time is 1.0 hour. – Auto repair shops typically charge between $75 and $150 per hour. – The complexity of the issue and the required parts can also affect the cost. – The expertise and experience of the mechanic can also impact the cost. – The location of the repair shop can also affect the cost due to differences in labor rates.

The P1A98 fault code relates to the StarterGenerator Control Module (SGCM) in hybrid vehicles.

The Accessory Power Module (APM) controls the flow of energy between the 42 volts DC and 14 volts DC buses via a bi-directional converter. The SGCM controls the transformation of DC voltage into three-phase AC power for the electric machine interface and for charging the 36-volt battery pack.

The fault code indicates a high voltage in the hybrid battery voltage sensor circuit.

What are the possible causes of the P1A98 automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the P1A98 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 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.

What are the steps to take if I find damaged components or broken, bent, pushed out, or corroded connector’s pins during the inspection of the SGCM circuit?

If you find damaged components or broken, bent, pushed out, or corroded connector’s pins during the inspection of the SGCM circuit, follow these steps. First, disconnect the battery to avoid any electrical shock. Then, carefully remove the damaged components and replace them with new ones. Next, repair or replace any broken, bent, pushed out, or corroded connector’s pins. Finally, reconnect the battery and test the SGCM circuit to ensure that the issue has been resolved.
