Start Clutch Pressure Control Calibration Procedures

Do the start clutch pressure control calibration procedures whenever you do any of these actions:

- Replace the PCM
- Reset the PCM
- Update the PCM
- Replace the transmission
- Overhaul the transmission
- Replace the engine assembly
- Overhaul the engine assembly
- Replace the lower valve body
- Replace the start clutch

Start Clutch Pressure Control Calibration Procedure mode

1. Connect the HDS to the DLC (A) located under the driver's side of the dashboard.





2. Turn the ignition switch to ON (II).

3. 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 DLC Circuit Troubleshooting (PGM-FI System).

4. Follow the HDS screen prompts in the Start Clutch Feedback Learn (see the HDS Operator's manual).

5. Test-drive the vehicle for several minutes, make sure the engine does not stall or flare when starting off, and verify that a problem does not occur on the start clutch pressure control system.

Calibration Procedure with SCS mode

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 DLC Circuit Troubleshooting (PGM-FI System).

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 for several minutes, make sure the engine does not stall or flare when starting off, and verify that a problem does not occur on the start clutch pressure control system.

Calibration by Driving the Vehicle

1. Warm up the engine to normal operating temperature (the radiator fan comes on twice).

2. 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.

3. Start the engine without a load (headlights, audio system, blower fan, rear window defogger, A/C, etc.), and let it idle.

4. Check the IMA battery charge level. If the IMA battery level indicator displays no level, hold the engine speed between 3,500 and 4,000 rpm without load (in P or N) until the level in the indicator is half full.

5. Drive the vehicle with the shift lever in D until the vehicle speed reaches 37 mph (60 km/h), then release the accelerator and decelerate without pressing the brake pedal for at least 5 seconds to reach completion.

6. Test-drive the vehicle for several minutes, make sure the engine does not stall or flare when starting off, and verify that a problem does not occur on the start clutch pressure control system.
