Continuously Variable Automatic Transmission (Cvt): Adjustments Honda Insight ZE1

Start Clutch Calibration Procedures

When the following parts are replaced or removed, the TCM must memorize the feedback signal for the start clutch control.

1. Battery
2. Back-up fuse
3. TCM
4. Transmission assembly
5. Lower valve body assembly
6. Engine assembly replacement or overhaul
7. Start clutch replacement.

There are two methods to calibrate the start clutch control using the Honda diagnostic system (HDS), or the SCS mode.

Scheme 227

1. Connect the HDS to the DLC (A).
2. Follow the tester's prompts in the Start Clutch Calibration Procedures (see the HDS Operator's manual).

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.
4. If the MIL comes on or the D indicator blinks, check the PGM-FI control system or the A/T control system.
5. Turn the ignition switch OFF.
6. Connect the HDS to the DLC, and follow the screen prompts to short-circuit the SCS signal terminal using the tester menu.
7. Press the brake pedal, and continue pressing the pedal until completion of the calibration.
8. Start the engine, and shift to the N position. Shift to the L position and return to the N position. Repeat this shifting three times within 20 seconds after the engine is started.
9. Check that the D indicator comes on for one minute with the shift lever in the N position, then goes off.
10. If the D indicator blinks, 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.
11. Shift to the D position, and check that the D indicator light comes on for 2 minutes, then it goes off.
12. If the D indicator blinks, or the D indicator comes on, and stays on (it does not go off after 1 minute). Turn the ignition switch OFF, restart the procedures with step 6.
13. Turn the ignition switch OFF to reach completion.
14. Test-drive the vehicle to verify that a problem does not occur on the start clutch control system.

Scheme 228

1. Remove the screws securing the mode switch, then remove the switch.
2. Disconnect the connector from the switch.
3. Check the S mode switch for continuity between connector terminals No. 2 and No. 3. There should be continuity while pressing the S mode switch, and no continuity when the switch released.
4. Check the D mode switch for continuity between connector terminals No. 1 and No. 3. There should be continuity while pressing the D mode switch, and no continuity when the switch is released.
5. If either switch is faulty, replace it.
6. If the switch is OK, but switch failure occurred, check and repair the wire harness on the mode switch circuit.

Scheme 229

1. Remove the screws securing the mode switch, then remove the switch.
2. Disconnect the connector from the switch.
3. Install the new mode switch.
