[SOLVED] Fixing U1162: Liftgate/Endgate Control Module Communication Lost

If you’re experiencing an illuminated Engine Light or Service Engine Soon Warning Light, it could be due to the automobile fault code: u1162.

This code is typically caused by a faulty LiftgateEndgate Control Module (LGMEGM), an open or shorted harness, or poor electrical connection.

It’s important to visually inspect the related wiring harness and connectors for any damage or corrosion. The repair time for this issue is estimated at 1.0, making it a relatively quick fix.

To interpret the fault code, check the “Possible Causes” listed above.

Repair Importance Level10.0 (Out of 10)
Estimated Repair TimeApproximately 1.0 hour
Repair Difficulty Level10.0 (Out of 10)

If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of u1162 fault code.

Here are the symptoms to look out for:

  • The automobile fault code U1162 has the following symptoms: Engine Light ON, Service Engine Soon Warning Light ON.

The automobile fault code u1162 can be caused by various factors, including a faulty control module and poor electrical connections.

  • The automobile fault code U1162 can be caused by a faulty Liftgate/Endgate Control Module (LGM/EGM).
  • It can also be caused by an open or shorted Liftgate/Endgate Control Module harness.
  • Additionally, a poor electrical connection in the Liftgate/Endgate Control Module circuit can also trigger this fault code.

Below are some possible fixes for the automobile fault code u1162, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code u1162, 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 automobile fault code U1162 can be diagnosed and fixed within an estimated repair time of 1.0 hour.

The cost of repair is influenced by the hourly rate charged by the auto repair shop, which typically ranges between $75 and $150 per hour. Therefore, the total cost of fixing the U1162 fault code will depend on the hourly rate charged by the auto repair shop and the estimated repair time required to diagnose and fix the issue.

The U1162 fault code is related to the class 2 serial data circuit in automobiles.

Modules in the circuit monitor for serial data communications during normal vehicle operation. When a module doesn’t receive a message for a critical operating parameter, it uses a default value for that parameter.

If a module doesn’t receive a Node Alive message from a learned identification number for 5 seconds, a Diagnostic Trouble Code (DTC) U1162 is set.

This fault code specifically indicates lost communications with the liftgateendgate control module.

What are the possible causes of the u1162 automobile fault code?

If you’re experiencing the u1162 fault code, your engine light may be on. This could be due to a faulty Liftgate/Endgate Control Module (LGM/EGM), an open or shorted harness, or poor electrical connection in the module circuit. To fix the issue, visually inspect the wiring harness and connectors for any damage or corrosion. Check for broken, bent, pushed out, or corroded connector pins.

How can I visually inspect the related wiring harness and connectors to fix the u1162 fault code?

If you’re experiencing an Engine Light ON or Service Engine Soon Warning Light due to a u1162 fault code, it could be caused by a faulty Liftgate/Endgate Control Module (LGM/EGM), an open or shorted harness, or a poor electrical connection. 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.

What are the signs that the Liftgate/Endgate Control Module harness is open or shorted, causing the u1162 fault code?

If the Liftgate/Endgate Control Module harness is open or shorted, it can cause the u1162 fault code, which triggers the Engine Light ON or Service Engine Soon Warning Light. The faulty Liftgate/Endgate Control Module (LGM/EGM) or poor electrical connection in the Liftgate/Endgate Control Module circuit can also be the cause. To fix this issue, one 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.
