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.

automatically activated for the Wiggle Test. Once the Wiggle Test
