Test 53, Check C1, C2 & C3 At Coil Pack

Turn key off, and disconnect ECA. Disconnect EDIS module from EDIS module tee, leaving EDIS diagnostic cable connected to vehicle harness connector. Set DVOM to 20-volt scale. Turn key on, but leave engine off. Measure voltage between breakout box pins No. J7 (BAT -) and J3 (C1), J7 and J6 (C2) and J7 and J10 (C3).

If each voltage reading is less than 0.5 volt, replace EDIS module. Remove all test equipment, and reconnect all components. Clear Continuous Memory, and check for fault codes. If each voltage reading is greater than 0.5 volt, repair short circuit. Remove all test equipment, and reconnect all components. Clear Continuous Memory, and check for fault codes.
