Применимость

Stored diagnostic trouble codes, counter values and frozen values can be read out and erased using this facility. The diagnostic system can identify 34 different faults in the form of diagnostic trouble codes.Diagnostic trouble codes (DTCs) can only be erased when all diagnostic trouble code (DTC) have been read at least once.When the engine control module (ECM) detects a fault, the values of certain parameters are frozen. These can be read off with the diagnostic trouble code (DTC). The following frozen values can be read off:

• Throttle position (TP) sensor position
• Oil temperature
• Vehicle speed
• Engine speed
