Test 56, Check C1, C2 & C3 For Short To Ground

Turn key off, and disconnect ECA. Disconnect EDIS coil tee from coil pack and vehicle harness connector. Disconnect EDIS module from EDIS module tee, leaving EDIS diagnostic cable connected to vehicle harness connector. Set DVOM to 2-k/ohm scale. Measure resistance between breakout box pins No. J7 (BAT -) and J3 (C1), J7 and J6 (C2) and J7 and J10 (C3).

If any resistance is less than 5 ohms, repair short circuit. Remove all test equipment, and reconnect all components. Clear Continuous Memory, and check for fault codes. If resistance readings are greater than 5 ohms, replace EDIS module. Remove all test equipment, and reconnect all components. Clear Continuous Memory, and check for fault codes.
