Measure voltage between J12 (C1C) and J60 (BAT-) on 3.0L and between J14 (C1C) and J60 (BAT-) on 3.8L. If voltage is less than 0.5 volt DC, go to step 9). If voltage is greater than 0.5 volt DC, go to step 20).
  9. Check C2 At Coil Pack  Turn ignition on. Measure voltage between J14 (C1C) and J60 (BAT-). If voltage is less than 0.5 volt, go to step 10). If voltage is greater than 0.5 volt, go to step 21).
  10. Check C3 At Coil Pack  Turn ignition on. Measure voltage between J13 (C3C) and J60 (BAT-). If voltage is less than 0.5 volt DC, go to step 11). If voltage is greater than 0.5 volt DC, go to step 22).
  11. Check C1 Driver At DIS Module  Connect test light between J3 (C1D) and J57 (BAT+). Crank engine. If test light does not blink once per crankshaft revolution, replace DIS module. If test light blinks once per crankshaft revolution, go to step 12).
  12. Check C2 Driver At DIS Module  Connect test light between J18 (C2D) and J57 (BAT+). Crank engine. If test light does not blink once per crankshaft revolution, replace DIS module. If test light blinks once per crankshaft revolution, go to step 13).
  13. Check C3 Driver At DIS Module  Connect test light between J6 (C3D) and J57 (BAT+). Crank engine. If test light does not blink once per crankshaft revolution, replace DIS module. If test light blinks once per crankshaft revolution, replace coil pack.
  14. Check C1 Circuit (Coil Disconnected)  Turn ignition off. Remove DIS diagnostic cable connector from coil. Leave diagnostic cable connected to vehicle harness. Set DVOM on 20-k/ohm DC range. Measure resistance between J12 (C1C) and J60 (BAT-) on 3.0L and between J14 (C1C) and J60 (BAT-) on 3.8L. If resistance is more than 2000 ohms, replace coil pack. If resistance is 2000 ohms or less, go to step 15).
  15. Turn ignition off. Disconnect coil tee from coil. Disconnect DIS diagnostic cable connector from DIS Module vehicle harness connector (terminals No. 7-12). Leave diagnostic cable connected to vehicle harness. Measure resistance between J3 (C1D) and J60 (BAT-). If resistance is greater than 10,000 ohms, replace DIS module. If resistance is 10,000 ohms or less, repair short to ground in C1D circuit.
  16. Check C2 Circuit  Turn ignition off. Disconnect coil tee from coil. Leave diagnostic cable connected to vehicle wiring harness. Measure resistance between J14 (C2C) and J60 (BAT-) on 3.0L and between J12 (C2C) and J60 (BAT-) on 3.8L. If resistance is greater than 2000 ohms, replace coil pack. If resistance is 2000 ohms or less, go to step 17).
