Introduction
  Z: Pinpoint Tests  

Note

This Pinpoint Test is intended to diagnose and isolate intermittent concerns for the following:

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 and will be measured with a digital multimeter. If the vehicle is a coil pack system with no start, perform the ignition test with the distributorless ignition system tester.
