  1. Ignition OFF and all vehicle systems OFF, disconnect the harness connector at the K35 Ignition Coil Module.
  2. Remove the fuel injector fuse.
  3. Connect a DMM between the appropriate K35 Ignition Coil Module control circuit listed below and ground. Set the DMM to the DC Hz scale and utilize the Min-Max function:
    • Ignition Coil 1 terminal D
    • Ignition Coil 2 terminal E
    • Ignition Coil 3 terminal F
    • Ignition Coil 4 terminal G
  4. Verify the DMM displays greater than 1.5 Hz while cranking the engine.
    • If less than 1.5 Hz 
    1. Ignition OFF, disconnect the X2 harness connector at the K20 Engine Control Module.
    2. Test for infinite resistance between the control circuit and ground.
      • If less than infinite resistance, repair the short to ground on the circuit.
      • If infinite resistance
    3. Test for less than 2 Ω in the control circuit end to end.
      • If 2 Ω or greater, repair the open/high resistance in the circuit.
      • If less than 2 Ω
    4. Ignition ON.
    5. Test for less than 1 V between the control circuit and ground.
      • If 1 V or greater, repair the short to voltage on the circuit.
      • If less than 1 V, replace the K20 Engine Control Module.
    • If greater than 1.5 Hz
