Wiggle Test (EEC-IV Vehicles)
The Wiggle Test, often referred to as the Continuous Monitor Test, is used to
locate intermittent electrical faults on EEC-IV vehicles. When the test is
activated, the tool will beep and display a message when a fault is present. If
the problem is fixed or goes away, the tone and message goes away. Refer to
the applicable vehicle service manual for circuits that can be tested.
✓ If the Alert was turned off in the tool Setup menu, it will be automatically
activated for the Wiggle Test. Once the Wiggle Test is complete, the alert
returns to its previous setting.
