Tools And Equipment




The DISplus/MoDIC as well as a reputable hand held multimeter can be used when testing inputs/components. It is best to make the checks at the ECM connection, this method includes testing the wiring harness.







The correct Universal Adapter for the MS S54 application should be used (#90 88 6 121 300). This will ensure the pin connectors and the harness will not be damaged.




When installing the Universal Adapter to the ECM (located in the Electronics Box in the engine compartment), make sure the ignition is switched off.

When Testing the Secondary Ignition System, use the High Tension clip of the DISplus. Refer to the HELP button for additional (on screen) connections.


CAUTION! Observe Safety Precautions, High Voltage is Present with the Engine Running
