The automobile fault code P1586 indicates a problem with the Engine Control Module (ECM). When this fault code is triggered, the Engine Light or Service Engine Soon Warning Light will turn on. The cause of this issue could be a faulty ECM, an open or shorted ECM harness, or a poor electrical connection in the ECM circuit.

To fix this problem, it is recommended to visually inspect the wiring harness and connectors related to the ECM. Look for any damaged components and check for broken, bent, pushed out, or corroded connector pins. The repair time for this issue is estimated to be around 1.0 hour.

To interpret the fault code, refer to the “Possible Causes” listed above and perform the necessary inspections and repairs.

The P1586 fault code relates to the MTAT encoding signal malfunction in the Engine Control Module (ECM) of a vehicle. The ECM is responsible for recognizing various options in the vehicle, such as MTAT, 24WD, and DPF. During the IG KEY ON process, the ECM automatically checks whether the ground line is grounded or opened to perform this recognition. If there is a problem with the recognition process or an error occurs, the engine power generation may be insufficient, and the glow lamp on the cluster will blink.

In the case of the P1586 fault code, it specifically indicates a malfunction in the encoding signal related to the MTAT option.

This could result in issues with the transmission system of the vehicle. To resolve this fault code, it is necessary to diagnose and repair the underlying issue with the MTAT encoding signal. This may involve checking the ECM connector for proper grounding and ensuring that the recognition process is functioning correctly. Seeking professional assistance or consulting the vehicle’s manual can help in addressing this fault code effectively.

What are the possible causes of fault code P1586 in an automobile?

If you see the Engine Light ON or the Service Engine Soon Warning Light in your automobile, it could be due to fault code P1586. This code is often caused by a faulty Engine Control Module (ECM), an open or shorted ECM harness, or a poor electrical connection in the ECM circuit. To fix this issue, start by visually inspecting the wiring harness and connectors. Look for any damaged components and check for broken, bent, pushed out, or corroded connector pins. Don’t forget to refer to the “Possible Causes” listed above for further troubleshooting.

How can I visually inspect the wiring harness and connectors to fix fault code P1586?

To fix fault code P1586, start by visually inspecting the wiring harness and connectors. Look for any damaged components and check if there are any broken, bent, pushed out, or corroded pins in the connectors. This can help identify if the issue lies with a faulty Engine Control Module (ECM), an open or shorted ECM harness, or a poor electrical connection in the ECM circuit. Take note of the possible causes mentioned above and address them accordingly.

What should I look for when checking for damaged components and connector pins to resolve fault code P1586?

When resolving fault code P1586, start by checking for damaged components and connector pins. This can be done by visually inspecting the related wiring harness and connectors. Look for any signs of damage such as broken, bent, pushed out, or corroded connector pins. By doing this, you can identify any faults in the Engine Control Module (ECM) or poor electrical connections in the ECM circuit. Take the necessary steps to fix these issues and ensure a smooth running engine.
