When the engine light is on or the service engine soon warning light is illuminated, it could be a sign of the p103d fault code.

  • The symptoms of the automobile fault code p103d include the Engine Light being ON or the Service Engine Soon Warning Light being illuminated.

The automobile fault code p103d can be caused by a faulty Engine Coolant Pump Control Module, an open or shorted harness, or a poor electrical connection in the module circuit.

  • The fault code P103D can be caused by: a faulty Engine Coolant Pump Control Module, an open or shorted harness for the Engine Coolant Pump Control Module, and a poor electrical connection in the Engine Coolant Pump Control Module circuit.

To fix the automobile fault code p103d, start by visually inspecting the wiring harness, connectors, and components for any damage or corrosion.

  • To fix the automobile fault code p103d, start by checking the possible causes mentioned above.
  • Then, visually inspect the wiring harness and connectors related to the issue.
  • Look for any damaged components and check for broken, bent, pushed out, or corroded connector pins.
  • This fix is estimated to take approximately 1.0 hour.

The factors influencing the diagnosis and fixing cost of the automobile fault code p103d are the estimated repair time and the hourly rate charged by auto repair shops. The estimated repair time for this fault code is 1.0 hour. Auto repair shops typically charge between $75 and $150 per hour for their services.

These factors will determine the overall cost of diagnosing and fixing the p103d fault code.

The P103D fault code is related to the Engine Coolant Pump Control Signal Message Counter. This code is set when there is an incorrect message counter for the control signal of the engine coolant pump.

Control modules in the vehicle monitor communication on the serial data circuits.

They exchange operating information and commands. Each module keeps track of transmit and receive error counters.

These counters increase with detected errors and decrease with error-free messages. When the Engine Coolant Pump Control Signal Message Counter is incorrect, the P103D code is triggered. This indicates a problem with the control signal for the engine coolant pump.

It is important to address this issue to ensure proper functioning of the coolant system in the vehicle.

What are the possible causes for the automobile fault code p103d?

If you see the engine light on or the service engine soon warning light, it could be due to the fault code P103D. This code is often caused by a faulty engine coolant pump control module, an open or shorted harness, or a poor electrical connection in the module circuit. To fix this issue, you should visually inspect the wiring harness and connectors, checking for any damage or corrosion. Additionally, look out for broken, bent, pushed out, or corroded pins in the connectors.

How can I visually inspect the wiring harness and connectors to fix the issue?

To fix the issue of the Engine Light being ON or the Service Engine Soon Warning Light, start by visually inspecting the wiring harness and connectors. This can help identify any faults in the Engine Coolant Pump Control Module, such as an open or shorted harness or a poor electrical connection. Look for damaged components and check for broken, bent, pushed out, or corroded pins in the connectors. This step is crucial in troubleshooting and resolving the problem.

What should I look for when checking for damaged components or corroded connector pins?

When troubleshooting an engine light or service engine soon warning light, it’s important to check for damaged components and corroded connector pins. These issues can be the cause of a faulty engine coolant pump control module or poor electrical connection. To fix the problem, visually inspect the wiring harness and connectors, paying close attention to any signs of damage. Look for broken, bent, pushed out, or corroded pins on the connectors. This thorough inspection will help identify and resolve the issue effectively.
