  Note

  • Ignition timing is not adjustable.
  • Ignition timing verification requires WDS or equivalent.

1. Turn off the electrical loads.

2. Warm up the engine as follows.

  (1) Start the engine.
  (2) Maintain the engine speed at approx. 3,000 rpm until the cooling fans start to operate.
  (3) Release the accelerator pedal.
  (4) Wait until the cooling fans stop.

3. Verify that the ignition timing (WDS: SPARKADV PID) is within the specification using WDS or equivalent.
