[SOLVED] Fix U185E Code: Fuel Injector Control Module Communication Lost

The automobile fault code U185E indicates a problem with the Body Control Module (BCM). The most common symptom is the Engine Light ON or Service Engine Soon Warning Light. The cause of this fault code could be a faulty BCM, an open or shorted BCM harness, or a poor electrical connection in the BCM circuit.

It is important to address this issue promptly as it can affect the overall performance of the vehicle.

The repair time for this fault code is estimated at 1.0. To fix the 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.

If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of u185e fault code.

Here are the symptoms to look out for:

  • The U185E fault code in an automobile can cause several symptoms, including the engine light turning on or the service engine soon warning light appearing.
  • Other symptoms may include issues with the transmission, such as difficulty shifting gears or the transmission slipping.
  • The vehicle may also experience a decrease in power or acceleration, and the engine may stall or hesitate during operation.
  • Additionally, the vehicle’s fuel efficiency may decrease, and there may be issues with the vehicle’s speedometer or other gauges.

The automobile fault code u185e can be caused by a faulty BCM, open or shorted harness, or poor electrical connection.

  • The automobile fault code U185E can be caused by a faulty Body Control Module (BCM).
  • It can also be caused by an open or shorted Body Control Module harness.
  • Additionally, a poor electrical connection in the Body Control Module circuit can also trigger this fault code.
  • These are the three main causes of the U185E fault code in automobiles.

Below are some possible fixes for the automobile fault code u185e, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code u185e, 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 U185E has an estimated repair time of 1.0 hour.

The cost of fixing this fault code is influenced by the repair time. Most auto repair shops charge between $75 and $150 per hour for their services.

Therefore, the fixing cost of U185E will range between $75 and $150, depending on the repair time required. These factors should be considered when estimating the cost of fixing the U185E fault code.

The U185E code is related to the Controller Area Network (CAN) serial data circuits in a vehicle. It indicates that the Fuel Injector Control Module has lost communication with the Body Control Module. This can happen if there is a malfunction in the CAN circuit or if the Fuel Injector Control Module loses power during the current ignition cycle.

Other modules that depend on information from the Fuel Injector Control Module will set a Loss of Communication Diagnostic Trouble Code (DTC) if this happens. If any of the CAN circuits are shorted to battery voltage, ground, or between them, no communication is possible on the CAN serial data bus, and a Diagnostic Trouble Code will be set.

What are the possible causes of the u185e automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the u185e fault code. This code is often caused by a faulty Body Control Module (BCM), an open or shorted BCM harness, or a poor electrical connection in the BCM 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 one visually inspect the related wiring harness and connectors to fix the u185e fault code?

If you’re experiencing the u185e fault code, which is indicated by the Engine Light ON or Service Engine Soon Warning Light, there are a few things you can do to fix it. Firstly, check for a faulty Body Control Module (BCM). If that’s not the issue, 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 visual inspection can help you identify any issues and get your vehicle back on track.

What are the signs that the Body Control Module harness is open or shorted, causing the u185e fault code?

If the engine light is on or the service engine soon warning light is illuminated, it could be a sign of a faulty Body Control Module (BCM) or an open or shorted BCM harness. The cause could also be a poor electrical connection in the BCM circuit. To fix this issue, it is recommended to visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.
