U0005 FORD Possible Causes
- Diagnosis of this diagnostic trouble code (DTC) is performed through vehicle symptoms
- Check for additional codes
- Faulty control module
- Control module harness is open or shorted
- Poor electrical connection in the control module circuit
How is U0005 FORD Code Repaired?
Begin by checking the “Possible Causes” listed above. Visually inspect the wiring harness and related connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector pins.

U0005 FORD Meaning
Multiplexing is a method of simultaneously sending 2 or more signals over the same circuit. Multiplexing allows 2 or more electronic modules (nodes) to communicate over a twisted pair network [data (+) and data (-)]. The information or messages that can be communicated on these wires consist of commands, status, or data. Multiplexing reduces vehicle weight by decreasing the number of redundant components and electrical wiring. The vehicle has 4 module communication networks connected to the DLC, located under the dashboard. The communication networks are: the High Speed Controller Area Network HEV (HS-CAN), the High Speed Controller Area Network (HS-CAN), the Medium Speed Controller Area Network (MS-CAN), and the Infotainment Controller Area Network (I-CAN). Diagnostic trouble code (DTC) U0005 is set when there is a failure in an HS-CAN (High Speed Controller Area Network), but the network may still be functional at a degraded level. One or more modules may not communicate and fail to send or receive messages.
