The wiggle test and output state test
If the scanner is left hooked up for roughly two minutes after the last code has been outputted, the wiggle test mode will become active. In this test mode, you can wiggle the wiring harness, tap on various sensors, etc to look for an intermittent fault. If an intermittent fault is detected, the scanner will momentarily light up, and if the intermittent fault lasts long enough, the EEC will store a fault code in the continuous memory.

The activators can be tested for operation using the output state test. After the last code is outputted, briefly floor the gas pedal, and then release. The light on the scanner will stay lighted, and all the activators will turn on . Another brief wide open throttle will turn off the light on the scanner, and will turn off all the activators. This on / off process can be repeated as many times as needed.


Search google for EEC-IV wiggle. I got a bunch of things that came up. Been awhile since I heard that phrase. :) thanks for reminding me!
