This Pinpoint Test is intended to diagnose and isolate intermittent concerns for the following:
All Electronic EC subsystems
Coil Pack ignition systems using the Distributorless Ignition System Tester (DIST)
This chart is used to determine which test to run for the suspect circuit. Corresponding PIDs to each circuit are listed. Some circuits do not have an associated PID or the PID may not be available and will to be measured with a digital multimeter. If the vehicle has a coil pack system with no start, perform the ignition test with the distributorless ignition system tester. Do not use the DIST for coil on plug applications.
