Features Specific to this System

The Motronic M 1.5.2 system is equipped with self-diagnosis. This means:

If the Motronic M 1.5.2 control unit recognizes a fault in the system, it will be stored after a certain period of time. If any trouble codes are stored, the engine telltale in the instrument is switched on.

Note:                       The Motronic M 1.5.2 permits readout of measured values while travelling. For this, the snapshot mode (F3 key) must be activated.

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

Important:           Trouble codes can only be deleted using TECH 1 or by disconnecting the ground lead from the battery for approx. 1 minute.

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

                          Replace closure plug on the diagnostic plug and diagnostic plug on the base.
