A fault code, also known as a Diagnostic Trouble Code (DTC), refers to errors within the system that inform your Mercedes-Benz vehicle about a malfunction. When a error code is detected, it activates a dashboard light or displays an error message to notify you to have your truck inspected and diagnosed.
The Gear Shift (GS) fault codes are a specific set of codes used to describe issues occurring in Mercedes-Benz vehicles. These codes are often marked with the prefix “GS,” followed by a number.
The “MR” fault codes in Mercedes-Benz vehicles typically refer to faults detected in the Engine Control Module (ECM). The ECM is responsible for monitoring and controlling the operation of the engine, including fuel injection, ignition timing, and emissions controls.
Gear Shift Fault Codes List
Gear Shift (GS) code will immediately identify if there are any malfunctions related to the gear shit functioning.
Engine Control Fault Codes
MR codes will help you identify engine-related malfunctions – usually, they are closely related to the vehicle’s speed, pressure, breaking or oil pressure.
Maintenance System Fault Codes
WS codes will help you identify maintenance system malfunctions – usually these are related to internal, temperature sensors, brake pads or oil temperature faults.
Automatic Transmission Programming Fault Codes
ATP codes will help you identify any malfunctions related to the gearbox and indirectly indicate other malfunctions connected to the vehicle transmission.
