2006 Chevrolet Cobalt SS, 4D Sedan, StandardSECTION Calibration Procedure with SCS mode
WARNING: This page is about a different car, the 2011 Honda Insight and 2010 Honda Insight. However, it is still accessible from the selected car via links, so may be relevant.
  1. Apply the parking brake, and block all four wheels securely.
  2. Warm up the engine to normal operating temperature (the radiator fan comes on twice).
  3. Make sure that the MIL does not come on and the D indicator does not blink. If the MIL comes on or the D indicator blinks, check the fuel and emissions system or the CVT control system.
  4. Turn the ignition switch to LOCK (0).
  5. Connect the HDS to the DLC (A) located under the driver's side of the dashboard.

  6. Turn the ignition switch to ON (II).
  7. Make sure the HDS communicates with the PCM, and go to the A/T Data List. If it does not, go to the DLC circuit troubleshooting.
  8. Follow the screen prompts to short-circuit the SCS signal terminal using the tester menu.
  9. Press the brake pedal, and continue pressing the pedal until the calibration is completed.
  10. Start the engine without a load (headlights, audio system, blower fan, rear window defogger, A/C, etc.), and let it idle.
  11. Six-position transmission: Shift the shift lever to N, shift to D, S, then L, and return to N. Repeat this shifting pattern two times within 20 seconds after the engine is started.

    Five-position transmission: Shift the shift lever to N, shift to D, then S, and return to N. Repeat this shifting pattern two times within 20 seconds after the engine is started.

  12. Follow the HDS screen prompts to open-circuit the SCS signal terminal using the tester menu; then disconnect the HDS from the DLC.
  13. Check that the D indicator comes on when the shift lever is in N, then goes off.
  14. If the D indicator blinks or does not come on, or if the indicator comes on and stays on, turn the ignition switch to LOCK (0), and restart the procedure with step  5.
  15. Shift to D, and check that the D indicator comes on, then goes off.
  16. If the D indicator blinks or does not come on, or if the indicator comes on and stays on, turn the ignition switch to LOCK (0), and restart the procedure with step  5.
  17. Test-drive the vehicle to verify that a problem does not occur on the start clutch pressure control system.

  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
