Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Tools And Equipment: Notes
The DIS/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 MS41.x application should be used (#88 88 6 614 410). This will ensure the pin connectors and the harness will not be damaged.
The interior of this Universal Adapter is shielded, therefore it is vital that the ground cable is connected to the vehicle chassis whenever the adapter is used.
The adapter uses a Printed Circuit board inside keeping the capacitive and inductive load to a minimum.
When installing the Universal Adapter to the ECM (located below the windshield on the passenger side of the engine compartment), make sure the ignition is switched off.
