The MR system can detect and store various types of faults that may occur in the engine or its components. These faults are indicated by error codes that can be read using a diagnostic tool or by observing the flashing sequence of the engine warning lamp on the instrument panel. The error codes are also known as MR fault codes or DTCs (diagnostic trouble codes).
The MR fault codes are divided into four categories: active, stored, intermittent, and historic. Active faults are those that are currently present and affect the engine operation. Stored faults are those that have occurred in the past but are not present at the moment. Intermittent faults are those that occur sporadically and may or may not affect the engine operation. Historic faults are those that have been cleared by the diagnostic tool or by disconnecting the battery.
The MR fault codes have a four-digit format, such as MR 0101 or MR 2020. The first two digits indicate the system or component that is affected by the fault, such as CAN (controller area network), crankshaft position sensor, oil pressure sensor, etc. The last two digits indicate the type or nature of the fault, such as short circuit to ground, open circuit, signal too low, etc.

Some examples of MR fault codes are:
MR 0101 CAN-L connection to FR is faulty. This means that there is a problem with the low-speed CAN bus wire that connects the MR and FR control units.
MR 0308 Crankshaft position sensor has short circuit to ground. This means that the crankshaft position sensor circuit has a low resistance to ground, which may cause a wrong signal to the MR control unit.
MR 1015 Oil temperature sensor has exceeded the measurement range (short circuit to positive, electrical circuit break). This means that the oil temperature sensor circuit has a high resistance or is disconnected, which may cause a wrong signal to the MR control unit.
MR 2020 Oil pressure is too low. This means that the oil pressure in the engine is below the minimum required value, which may cause engine damage.
The MR fault codes can help to diagnose and troubleshoot various problems that may affect the engine performance, fuel consumption, emission level, or drivability of the vehicle. However, some faults may have multiple possible causes or symptoms, and some faults may not be detected by the MR system at all. Therefore, it is important to use other methods of diagnosis, such as visual inspection, mechanical tests, or expert advice, in addition to reading the MR fault codes.
