Checking Coil Pack

Turn key off, and disconnect coil pack. Measure resistance between coil pack terminal No. 4 and all other terminals. See Figure . If each resistance is greater than 0.8 ohm, replace coil pack. If any resistance is less than 0.5 ohm, replace coil pack and ICM. Remove all test equipment, and reconnect all components. Clear Continuous Memory and check for fault codes.
