Performance Controls: Tools and Equipment

Tools and Equipment





The DIS plus/Gt1 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 MS45 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 below the windshield on the passenger side of the engine compartment), make sure the ignition is switched off.

NOTE for MS45: Allow at least 3 minutes to elapse after the key was set to the UOFF position before disconnecting the ECM/ TCM.
This win allow sufficient time to complete the DM n test Voltage may be present (up to 3 minutes) causing damage to the ECM/TCM if they are disconnected during this time period (arcing).

VANES





The electrical/hydraulic function can be checked statically by using the adapter tools and shop supplied regulated compressed air.
Special Tool # 90 88 6 113 450 adapts regulated compressed air to substitute for engine oil pressure required to move the VANES piston. Special Tool # 90 88 6 126 410 allows battery voltage and ground to activate the solenoid.
