Coil Harness Continuity Check
- Connect ohmmeter leads to coil "TACH" terminal and to 4-wire harness connector terminal that mates with control module green wire.
- If resistance is less than 1 ohm, proceed to "Ignition Coil Primary Resistance Check ". If more than 1 ohm, repair or replace green wire from coil to 4-wire harness connector.
