Test 55, Check C1, C2 & C3 For Short To Ground

Turn key off, and disconnect ECA. 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 each resistance is less than 1200 ohms, go to next test. If each resistance is greater than 1200 ohms, replace coil pack. Remove all test equipment, and reconnect all components. Clear Continuous Memory, and check for fault codes.
