• Turn ignition on.
• Follow operating instructions from NGS tester menu.
• Press and release accelerator pedal to cycle output state high on relays, solenoids, WAIT TO START light, CID, IDM EF, FDCS, and TCIL. When accelerator pedal is pressed for first time, glow plug relay will receive a 5 second on-command.
• After test has been completed, cycle ignition off before performing other self-tests or driving vehicle.
