Preliminary Checks

  1. Turn ignition off. Disconnect ignition ECU connector. ECU is located behind panel on right side of accelerator pedal.
  2. Push out clip and disconnect ECU connector. Remove cover from ECU connector, exposing terminal identification numbers. Visually inspect all terminal connector sleeves to ensure all terminals are at same height.
