Start Clutch Pressure Control Calibration Procedures
Start Clutch Pressure Control Calibration ProceduresWhen the following parts are replaced or removed, the TCM must memorize the feedback signal for the start clutch pressure control system.
^ Battery
^ Back-up fuse
^ TCM
^ Transmission
^ Start clutch
^ Start clutch pressure control valve
^ CVT drive pulley pressure control valve
^ CVT driven pulley pressure control valve
^ Engine assembly
Start Clutch Pressure Control Calibration Procedure mode
1. Connect the HDS to the DLC (A).
2. Follow the tester's prompts in the Start Clutch Pressure Control Calibration Procedures.
Calibration Procedure with SCS mode
1. Apply 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. If the MIL comes on or the D indicator blinks, check the fuel and emissions system or the A/T control system.
4. Turn the ignition switch OFF.
5. Connect the HDS to the DLC, and follow the screen prompts to short-circuit the SCS signal terminal using the tester menu.
6. Press the brake pedal, and continue pressing the pedal until the calibration is completed.
7. Start the engine with no-load condition, but turn the headlights on. The headlights must be on during calibration.
8. Shift the shift lever to the N position, shift to D, S, then L, and return to the N position. Repeat this shifting pattern three times within 20 seconds after the engine is started.
9. Check that the D indicator comes on when the shift lever is in the N position, then goes off in one minute.
10. If the D indicator blinks or does not come on, or if the indicator comes on and stays on, turn the ignition switch OFF, and restart the procedure with step 5.
11. Shift to the D position, and check that the D indicator comes on, then goes off.
12. If the D indicator blinks or does not come on, or if the indicator comes on and stays on, turn the ignition switch OFF, and restart the procedure with step 5.
13. Turn the ignition switch OFF to complete the procedure.
14. Test-drive the vehicle to verify that a problem does not occur on the start clutch pressure control system.
Calibration Procedure by Driving the Vehicle
1. Warm up the engine to normal operating temperature (the radiator fan comes on).
2. Start the engine with a no-load condition, then immediately turn the headlights on.
3. Drive the vehicle in the D position until the vehicle speed reaches 37 mph (60 km/h), then release the accelerator and decelerate without pressing the brake pedal for more than 5 seconds to reach completion.
4. Verify that a problem does not occur on the start clutch pressure control system.
