The automobile fault code U18A6 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 U18A6 will be between $75 and $150, depending on the repair time required.

The U18A6 code indicates a communication problem with the right side object detection control module. The side object sensor modules use radar to detect nearby objects and communicate with each other through a private network.

The left sensor is the master and communicates with the scan tool, while the right sensor communicates with the left sensor through serial data. If the right sensor fails to communicate with the left sensor, the visual indicator on the right side outside rearview mirror may not illuminate when an object is detected in the right-side blind zone.

The DTC will set a supervised periodic message indicating the transmitter device availability that has not been received.

What are the possible causes of the u18a6 automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the u18a6 fault code. This code is caused by a faulty right object detection 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, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.

How can I visually inspect the wiring harness and connectors related to the Right Object Detection Control Module?

If you’re experiencing an Engine Light ON (or Service Engine Soon Warning Light) due to a faulty Right Object Detection Control Module, you can visually inspect the related wiring harness and connectors to fix the issue. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. This will help you identify if the Right Object Detection Control Module harness is open or shorted, or if the circuit has a poor electrical connection.

What should I do if I find damaged components or broken, bent, pushed out, or corroded connector’s pins during the inspection for the u18a6 fault code?

If you find damaged components or broken, bent, pushed out, or corroded connector’s pins during the inspection for the u18a6 fault code, you should visually inspect the related wiring harness and connectors. Check for any possible causes listed above and fix them accordingly. It is important to ensure that the Right Object Detection Control Module harness is not open or shorted and that the circuit has a good electrical connection.
