  • Page 33 Diagnosis > Parameters < Since the causes of faults can be interpreted differently by the control unit, it is often not sufficient to read out only the fault memory. In many cases, either fault codes are not entered or it is not possible to obtain an unequivocal statement about the defective component from the fault text. Example 1: The engine temperature may vary within a range of -30°C to +120°C. If the sensor signals +9.0°C, although the actual temperature in the engine is +80°C, the control unit will determine an incorrect injection time. No fault code will be set, as this temperature is logical for the control unit. Example 2 Fault text: Lambda probe signal faulty In both cases, a diagnosis can only be carried out if the corresponding parameters are read out. mega mac 50 reads the parameters out and presents them in plain text. If up to 4 parameters are selected, they will also be displayed in graphic form. A maximum of 8 parameters can be called up, but in this case they will not be presented in graphic form. A task-orientated selection of the parameters facilitates fault diagnosis. Information on the parameters is stored. Procedure 1.

  • Page 55 Safety precautions regarding the risk of injury: When the engine is running, injuries may arise from rotating parts (fan blades, belt drives, etc.). If the vehicle is not prevented from rolling away, you could be trapped by it. • Keep the hands well clear of rotating parts when the engine is running. • Prevent the car from rolling away unintentionally (handbrake). • In the case of automatic vehicles, also set the selector lever to P position. • Do no lay connecting leads near rotating parts. Safety precautions regarding noise: To prevent hearing defects, take the following measures: • Protect workstations in the vicinity of the testing stations against noise. • Use noise insulation equipment. Safety precautions: Caustic injuries: If the LCD display is damaged, the risk of caustic injuries will arise through the escape of crystal fluid. Wash any parts of the body or clothing immediately with water (consult a doctor). • Consult a doctor immediately if the fluid has been inhaled or swallowed. mega macs 50 Section O 3/...
