  • This fix will take an estimated repair time of 1.0 hour.

The automobile fault code U179D has an estimated repair time of 1.0 hour.

The cost of fixing this code varies depending on the auto repair shop, but it is common for them to charge between $75 and $150 per hour.

These factors are influential in determining the overall cost of fixing the U179D fault code.

The U179D code is related to the Local Interconnect Network (LIN) Bus in automobiles. It occurs when there is a loss of serial data communication between the Brake System Control Module 2 and other LIN devices within the subsystem. This code is set by the master control module when a supervised periodic message from the Brake System Control Module 2 is not received.

The code indicates that there is no communication with the Brake System Control Module 2 on the Chassis Expansion Bu.

What are the possible causes of the u179d automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the u179d fault code. This code is usually caused by a faulty brake system control module 2, an open or shorted harness, or a poor electrical connection in the brake system control module 2 circuit. To fix this issue, you should visually inspect the 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 related wiring harness and connectors to fix the u179d fault code?

If you’re experiencing the u179d fault code, which causes the engine light to turn on, you may need to visually inspect the related wiring harness and connectors. This fault code can be caused by a faulty Brake System Control Module 2, an open or shorted harness, or a poor electrical connection. To fix the issue, check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. It’s important to inspect the wiring harness and connectors thoroughly to ensure that the issue is resolved.

What are the signs that the Brake System Control Module 2 harness is open or shorted, causing the u179d fault code?

If the Brake System Control Module 2 harness is open or shorted, it can cause the u179d fault code, which triggers the Engine Light or Service Engine Soon Warning Light. The root cause of this issue is a faulty Brake System Control Module 2 or a poor electrical connection in the circuit. To fix this problem, 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.
