Test No. 8

  1. Check ENGINE fuse. If fuse is faulty, replace ENGINE fuse (repair circuit if shorted). If fuse is okay, remove driver front side trim panel. Turn ignition on. Measure voltage at terminal "A" (Black/Light Green wire) of starter cut relay 6-pin connector. SeeFigure . If battery voltage is not present, repair wiring between ENGINE fuse and starter cut relay.
  2. If battery voltage is present, turn ignition off. Disconnect starter cut relay 6-pin connector. Check continuity between terminals "C" and "F" of starter cut relay. If continuity exists, replace starter cut relay. If continuity does not exist, apply battery voltage across terminals "A" and "B" of starter cut relay. Check continuity between terminals "C" and "F" of starter cut relay.
  3. If continuity does not exist, replace starter cut relay. If continuity exists, turn ignition on. Measure voltage at terminal 2D (Light Green/Red wire) of CPU No. 2 8-pin connector. If battery voltage is not present, repair wiring between starter cut relay and CPU No. 2. If battery voltage is present, replace CPU No. 2.
