Notes on Intermittents
To diagnose an intermittent resume/accel function, turn cruise control dash switch to "ON" position and backprobe ECM pin "B6" with a voltmeter to ground. Terminal "B6" should show 12 volts with turn cruise dash switch to "ON" position and backprobe ECM pin "B4" with a voltmeter to ground. Terminal "B6" should show 12 volts with "RESUME/ACCEL" switch depressed and zero volts with "RESUME/ACCEL" switch released. Cycle switch while manipulating wiring and connectors.
