SYNCHRONIZATION POSITION CALIBRATION
For smoother shifting, the TCM learns the synchronization position of the transaxle gears. Perform synchronization position calibration of the multi-mode manual transaxle while driving the vehicle after repairing system components.
Tech Tips
If clutch fluid line parts are installed, bleed the air from the lines before performing initialization.
When replacing the following parts, proceed with the operation in the order listed in the table below.
| Part Installed | Operation Order | See Procedure |
|---|---|---|
|
1. Initialization of multi-mode manual transaxle system [Tester display: Initialization of ECU] |

| 2. Learning of multi-mode manual transaxle system | ||
| 3. Synchronization position calibration | See below | |

Note
Do not clear (initialize) parts other than those specified in the "Part Installed" column in the table above.
While driving the vehicle in M mode, shift up and down between 1st and 6th at the vehicle speeds specified below.
Check that the gears shift smoothly.
| Gear Change | Gear Position | Vehicle Speed |
|---|---|---|
| Up shift | 1st → 2nd | 25 to 40 km/h (15.5 to 24.9 mph) |
| 2nd → 3rd | 47 to 68 km/h (29.2 to 42.3 mph) | |
| 3rd → 4th | 69 to 98 km/h (42.9 to 60.9 mph) | |
| 4th → 5th | 92 to 133 km/h (57.2 to 82.6 mph) | |
| 5th → 6th | 99 to 181 km/h (61.5 to 112.5 mph) | |
| Down shift | 2nd → 1st | 25 to 31 km/h (15.5 to 19.3 mph) |
Tech Tips
Leave an interval of more than 2 seconds between gear changes.
If there is a shock when changing gears after synchronization position calibration, perform synchronization position calibration again.
