Turbo Models
INPUT SIGNALS SPECIFICATION (TURBO MODELS)
| Signal name | Major function |
|---|---|
| Accelerator pedal position sensor | Indicates the throttle opening. This signal is used to determine shift point, line pressure, and lockup engaging vehicle speed, which vary with engine load. |
| Front vehicle speed sensor (located on transmission case) | Indicates the vehicle speed. This signal is used for control of gear shifting, lockup engaging, line pressure, and transfer clutch operation. |
| Rear vehicle speed sensor (located on extension case) | Used to control transfer clutch, and also as backup signal in case of failure of front vehicle speed sensor. |
| Engine speed signal | Indicates the engine speed. This signal is used for control of lockup clutch to ensure smooth engagement. |
| Inhibitor switch | Used to determine gears and line pressures in each of ranges P, R, N, D, 3, 2 and 1. |
| ATF temperature sensor | Indicates the ATF temperature. This signal is used for inhibition of lock-up, release of overdrive (OD) and determination of ATF temperature. |
| ABS signal | Used when ABS is operating to optimize ABS control. In this control, transfer clutch torque load capacity is adjusted to eliminate the influence of engine braking and reduce the degree of coupling between front and rear wheels. |
| Torque converter turbine speed sensor | Tells the rotation speed of the input shaft. The proportion of this speed to the vehicle speed determines whether shifting should be made or not. |
| CAN communication signals | Receives information from ECM to control the transmission. |
| Sports shift mode switch (vehicles with sports shift) | Used to switch between normal shift mode and sports shift mode. |
| Upshift switch (vehicles with sports shift) | The TCM makes upshift control when a signal is input while driving in sports shift mode. |
| Downshift switch (vehicles with sports shift) | The TCM makes downshift control when a signal is input while driving in sports shift mode. |
