Diagnosis >Parameter< As the ECU interprets fault reasons differently, it is often not enough only to read out the fault memory. Fault codes are often not stored or the fault text delivers only insufficient comments on the defective component. Example 1: Engine temperature can be within a range of -30°C to +120°C. If the sensor reports +9.0°C, but real engine temperature is +80°C, then ECU will calculate a wrong injection time. A fault code will not be set, as this temperature is logic for the ECU.
