The automobile fault code U183A 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 U183A will range between $75 and $150, depending on the repair time required.

The U183A code indicates a loss of communication with the Telematics Communication Interface Control Module on High Speed CAN Bu. The serial data circuit is used by devices in the vehicle to communicate with each other.

When a device stops communicating on the serial data circuit, the state of health message it normally sends disappears.

Other devices on the serial data circuit detect the absence of the state of health message and set a DTC associated with the loss of the state of health of the non-communicating device.

The U183A code sets when a supervised periodic message that includes the transmitter device availability has not been received.

What are the possible causes of the u183a automobile fault code?

If you see the engine light on or the service engine soon warning light, it could be due to the u183a fault code. This code is usually caused by a faulty Telematics Communication Interface Control Module or an open or shorted harness. 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.
