| 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, and D. |
| ATF temperature sensor |
Indicates the ATF temperature. This signal is used for inhibition of lockup, release of OD and determination of ATF temperature. |
| FWD switch |
Used for changing the mode from AWD to FWD. Also used for adapting the vehicle to FWD tester roller. Changeover from AWD to FWD can be made by inserting a fuse into the fuse holder. |
| 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, ABSCM and body integrated unit to control the transmission. |
