  3. Go to PGM-FI, and check for DTCs.
  4. Do the following tests while monitoring parameters in the PGM-FI DATA LIST with the HDS.
    NOTE: Intermittent failures are often caused by loose circuit connections. While monitoring cruise control inputs, flex their circuits, and note if any of the test results change.
