CVT Start Clutch Calibration Procedures

• When any of the following items is applied, the feedback signal memory for the start clutch control in the PCM is cleared. The PCM must be memorized the feedback signal for the start clutch control.
  
  • Disconnecting the battery terminal(s)
    
  • Removing the No. 20 ECU (15A) fuse in the under-dash fuse/relay box
    
  • Replaced the start clutch
    
  • Replaced the control valve body
    
  • Overhauled the transmission assembly
    
  • Replaced the transmission assembly
    
  • Overhauled the engine assembly
    
  • Replaced the engine assembly
    
• There are two methods to calibrate the start clutch control during halts and with driving the vehicle, use one of these methods.
  

Calibration Procedure During Halts

Special Tools Required
DLC pin box (  07WAJ-0010100)
 

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).

3.	Make sure that the MIL does not come on and the [D] indicator does not blink.

4.	If the MIL comes on or [D] indicator blinks, check the fuel and emissions system or the A/T control system, and recheck after checking.

5.	Turn the ignition switch OFF.

6.	Connect the special tool (07WAJ-0010100) to the data link connector, then connect the jumper wire between terminals 4 and 9 at the special tool, and turn the switch ON to short-circuit SCS to ground.

7.	Press the brake pedal, and continue pressing the pedal unit complete of the calibration.

8.	Start the engine under no-load conditions, then turn the headlights on. The headlights must be turned on during calibration.

9.	Shift the shift lever into [N] position, and shift to [D], [S], [L] position, then shift back to [S], [D], and into [N] in 20 seconds after the engine is started. The shift lever should stop at each position. Repeat this shifting twice.

10.	Check that the [D] indicator comes on for one minute with the shift lever is in [N] position, then the indicator goes off.

11.	If the [D] indicator blinks not to come on, or the [D] indicator comes on, and stays on (it does not go off after one minute). Turn the ignition switch OFF, restart the procedures with step 6.

12.	Shift to [D] position, and check that the [D] indicator comes on for 2 minutes, then it goes off.

13.	If the [D] indicator blinks not to come on, or the [D] indicator comes on, and stays on (it does not go off after one minute). Turn the ignition switch OFF, restart the procedures with step 6.

14.	Turn the ignition switch OFF to reach completion.

15.	Test-drive the vehicle to verify that a problem does not occur on the start clutch control system.

Calibration Procedure with Driving the Vehicle

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

2.	Start the engine under no-load conditions, then turn the headlights on.

3.	Start off in [D] position, and drive the vehicle until vehicle speed reaches 60 km/h (37 mph), then decelerate the vehicle in more than 5 seconds without pressing the brake pedal to reach completion.

4.	Test-drive the vehicle to verify that a problem does not occur on the start clutch control system.
