Features Specific to this System

The Motronic M 1.5.4 system is equipped with self - diagnosis. This means:

If the Motronic M 1.5.4 control unit recognizes a system fault, it is stored after a certain period of time. The engine telltale in the instrument illuminates whenever trouble codes are stored.

Note:                  The Motronic M 1.5.4 permits readout of measured values while travelling.

                                 For this, the snapshot mode (key F3) must be activated.

                                 This allows sporadic faults (e. g. loose contacts) to be detected.

Important:           Trouble codes can only be deleted using TECH 1.

                                 After completion of diagnosis with TECH 1, the ignition must be switched off at least once.
