U0180 can be serious depending on which module lost communication. Safety-critical modules (ABS, airbag, steering) require immediate attention.

Can I drive with U0180?

Driving with U0180 is not recommended if safety-critical modules (ABS, SRS, power steering) are affected. The vehicle may have reduced functionality.

Will U0180 clear itself?

U0180 may clear if the fault is intermittent, but it will likely return if the underlying wiring or module issue is not resolved. Use a scan tool to monitor pending and confirmed codes.

U0180 - Lost Communication With Seat Module Third Row Right

U0180 is a Diagnostic Trouble Code (DTC) in the Network Communication (U) category. It indicates lost communication with seat module third row right. These codes relate to the vehicle's onboard communication network (CAN bus, LIN bus, etc.) and module-to-module data exchange. When U0180 is set, it means one or more control modules have detected a communication fault, data integrity issue, or software incompatibility on the vehicle network.

What is U0180?

U0180 is a Diagnostic Trouble Code (DTC) in the Network Communication (U) category. It indicates lost communication with seat module third row right. These codes relate to the vehicle's onboard communication network (CAN bus, LIN bus, etc.) and module-to-module data exchange.

When U0180 is set, it means one or more control modules have detected a communication fault, data integrity issue, or software incompatibility on the vehicle network.

Common Symptoms

Module-specific function not working
Warning lights related to affected system
Reduced functionality
Communication errors on scan tool
Other modules setting related codes

Possible Causes

Open or shorted communication wiring
Faulty module power or ground
Failed control module
Corroded connector pins
Network bus fault

Step-by-Step Diagnosis

Connect a professional-grade OBD2 scanner and check for all active and pending U-codes.
Identify which modules are communicating and which are not.
Check power, ground, and communication wiring for the Seat Module Third Row Right using a wiring diagram.
Perform a voltage drop test on power and ground circuits to the affected module.
Check CAN bus resistance (should be ~60 ohms between CAN-High and CAN-Low).
Use a scan tool to monitor live data from modules that are still communicating.
Perform a wiggle test on wiring harnesses while monitoring for communication recovery.
If a module replacement is suspected, verify correct part number and programming requirements.
Clear codes and retest after repairs.

Recommended Repairs

Repair any damaged wiring, connectors, or terminals. Ensure proper routing and secure mounting.
Clean corroded connector pins with electrical contact cleaner.
Replace blown fuses and verify correct amperage rating.
If a module requires programming, ensure it is done with the correct software version.
Update or reflash module software if a TSB applies.
Replace failed control module if testing confirms internal failure.
Verify all repairs by checking module communication with a scan tool.
