If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of p1ac1 fault code.

Here are the symptoms to look out for:

  • The P1AC1 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, rough idling, stalling, and difficulty starting the engine.
  • Additionally, the vehicle may experience a decrease in acceleration or a loss of power while driving.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle.

The P1AC1 fault code can be caused by a faulty control module, openshorted harness, or poor electrical connection.

  • The automobile fault code P1AC1 can be caused by a faulty Starter/Generator Control Module Cooling Fan Relay.
  • It can also be caused by an open or shorted Starter/Generator Control Module Cooling Fan Relay harness.
  • Additionally, a poor electrical connection in the Starter/Generator Control Module Cooling Fan Relay circuit can also trigger this fault code.

To fix the p1ac1 automobile fault code, check the possible causes and inspect related components for damage or corrosion.

  • To fix the automobile fault code p1ac1, 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 factors that influence the cost of diagnosing and fixing the automobile fault code P1AC1 are the estimated repair time and the hourly rate charged by the auto repair shop.

The estimated repair time for this fault code is 1.0 hour.

The cost of repair is influenced by the hourly rate charged by the auto repair shop, which is typically between $75 and $150 per hour.

These factors should be considered when estimating the cost of diagnosing and fixing the P1AC1 fault code.

The P1AC1 fault code is related to the StarterGenerator Control Module (SGCM).

The SGCM controls the coolant fan operation by applying voltage to the coolant fan relay control circuit.

The SGCM monitors the relay control circuits for short to ground, short to voltage, or an open circuit.

If the SGCM detects an improper voltage level on the coolant fan relay control circuit, then DTC P1AC1 or P1AC2 will set and the driver will be disabled.

The P1AC1 code specifically indicates low voltage on the coolant fan relay control circuit.

What are the possible causes of the P1AC1 fault code?

If you’re experiencing the P1AC1 fault code, you may notice that your engine light is on. This could be due to a faulty Starter/Generator Control Module Cooling Fan Relay, an open or shorted harness, or a poor electrical connection in the circuit. To fix the issue, it’s recommended to visually inspect the wiring harness and connectors for any damage or corrosion, and check for broken or bent pins.

How can I visually inspect the wiring harness and connectors related to the Starter/Generator Control Module Cooling Fan Relay?

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 Cooling Fan Relay. 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. This will help you identify if the Starter/Generator Control Module Cooling Fan Relay harness is open or shorted, or if there is a poor electrical connection in the circuit.

What are the signs of damaged components or broken, bent, pushed out, or corroded connector’s pins that I should look for when checking for the P1AC1 fault code?

If you’re checking for the P1AC1 fault code, look for the Engine Light ON or Service Engine Soon Warning Light. The cause could be a faulty Starter/Generator Control Module Cooling Fan Relay, an open or shorted harness, or a poor electrical connection. To fix it, visually inspect the wiring harness and connectors, and check for damaged components or broken, bent, pushed out, or corroded connector’s pins.
