The U1200 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 does not associate an identification number with at least one critical parameter within 5 seconds of beginning serial data communication, the U1200 Diagnostic Trouble Code (DTC) is set. The U1200 code specifically indicates invalid or missing data for seat motioncontrol.

What are the possible causes of the u1200 automobile fault code when the engine light is on?

If the engine light is on and the u1200 fault code is detected, it could be due to a faulty module that is not communicating, an open or shorted module harness, or a poor electrical connection in the module circuit. 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.

How can a faulty module that is not communicating be fixed when it triggers the u1200 fault code?
