When diagnosing a GMC Yukon 4WD Service Message, the first step is to inspect the drivetrain components. This includes checking for any leaks, damage, or other issues that may be causing the message to appear. Additionally, check all of the related electrical connections and wiring to ensure that everything is properly connected and functioning correctly. If any problems are found during this initial inspection, they should be addressed before moving onto further diagnostics.

Checking Fluid Levels

Testing 4WD System

Once all of the fluids and filters have been checked and corrected if necessary, it is time to test out the 4WD system itself. This can be done by engaging each of the individual drive modes (4H, 4L, AWD) and seeing if they work properly without any issues. If any problems are identified during this testing phase, then further diagnostics may be required in order to locate and repair them.

Scanning for Error Codes

If all of the above steps have been completed without identifying any problems with the drivetrain components or 4WD system itself then it may be necessary to scan for error codes using an OBD-II scanner tool. These scanners can detect several different types of error codes which can indicate various faults within the system that could be causing the service message to appear.
