Start Clutch Calibration Procedures



Start Clutch Calibration Procedures

When the following the parts are replaced, the PCM must memorize the feedback signal for the start clutch control.
^ PCM
^ Transmission assembly
^ Lower valve body assembly
^ Engine assembly replacement or overhaul

1. Start the engine, and warm up to normal operating temperature (the radiator fan comes on).
2. Shift to the D position.
3. Drive the vehicle on a flat road.
4. Accelerate to the speed 37 mph (60 km/h), then release the accelerator and decelerate for 5 seconds. Do not press the brake pedal to decelerate. The start clutch feedback control signal have been memorized in the PCM.
5. Test-drive the vehicle and check the engine does not stall and the vehicle can start off smoothly.
6. If the engine stalls or any shifting failure occurs at starting off, re-calibrate the start clutch feedback control signal.
