Wiggle Test

The wiggle test is designed to help identify and locate intermittent failures in the vehicle wiring harness and system components. Upon entering wiggle test, several inputs and outputs of the Generic Electronic Module (GEM) are monitored for change of state. When a state change is encountered, an audible tone can be heard, and a counter displayed on the New Generation Star (NGS) will increment. By initiating wiggle test and pulling on different areas of the vehicle harness, intermittent open and short circuits can be located and serviced.
