A model-specific diagnostic approach
Begin by identifying the exact chassis, engine, transmission and options. Record when the problem occurs, preserve freeze-frame data and perform a full relevant module scan. Distinguish mechanical, electrical, hydraulic and software causes through direct testing rather than replacing the component named by a code.
Manufacturer-specific considerations
A research case or technical bulletin may identify a possible diagnostic path, but it is not proof that a particular customer's vehicle has the same fault.
Repair confirmation
Verify the repair by reproducing the original operating conditions and confirming no related faults return.
The source research addresses Range Rover applications described as 2014–2016 (Range Rover L405). The correct testing depends on the exact year, engine, drivetrain and equipment.
Symptoms an owner may notice
Wipers ran continuously with key on despite switch position; stopped and parked correctly key-off.
Driver-door soft-close feature/latch did not engage.
Front wipers always on with ignition on.
Driver-door soft close inoperative.
What diagnosis involves
The available case notes describe checks such as Command wipers with scan tool; Remove and inspect multifunction switch. The actual vehicle must be evaluated before any repair recommendation.
Findings recorded in the cases included No difference; Plastic housing broken. These observations may guide testing but cannot be assumed on another vehicle.
Documented causes and repair decisions
In the researched cases, identified causes included Broken multifunction-switch plastic housing; Door latch not working properly. A different vehicle with the same symptoms may have a different underlying problem.
Reported successful repairs in the research included Replace multifunction switch; Replace driver-door latch. These are external case outcomes, not claims that Mich’s performed those specific repairs.
Some attempted repairs were ineffective or temporary, including Disconnect switch, apply dielectric grease and reconnect per prior TSB — unsuccessful. That is one reason to verify the failure before replacing components.
