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 Scan Tool beeps and displays 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
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.
