• A list of the support data is shown in the following table.

Front Wheel Speed 

1. Display: 0 - 255 km/h (0 - 158 MPH) 

The front wheel speed is displayed. This signal is used for the shift control, lock-up control, line pressure control, and transfer control.

ATF Temp. 

1. Display: -40 to 215°C (-40 to 419°F) 

The ATF temperature via the signal from the ATF temperature sensor is displayed.

Gear Position 

1. Display: 

The present gear position is displayed. The gear position is calculated from the engine speed and torque converter turbine speed.

Line Pressure Duty Ratio 

1. Display: 0 - 123% 

The duty value of the line pressure duty solenoid is displayed. The line pressure duty solenoid is regulated by the TCM, adjusting the line pressure to the optimum value depending on driving conditions.

Lock Up Duty Ratio 

1. Display: 0 - 123% 

The duty value of the lock-up duty solenoid is displayed. The lock-up duty solenoid is regulated by the TCM. Because the lock-up duty solenoid controls the lock-up control valve, the lock-up clutch engages and disengages smoothly.

Transfer Duty Ratio 

1. Display: 0 - 123% 

The duty value of the transfer duty solenoid is displayed. The transfer duty solenoid is regulated by the TCM, adjusting the transfer clutch oil pressure and controlling the driving force of the rear wheels.

Turbine Revolution Speed 

1. Display: 0 - 8,160 rpm 

The input shaft speed detected by the torque converter speed sensor is displayed. This signal is used to control the line pressure and 2 - 4 brake pressure control timing during shifting.

Throttle Sensor Power 

1. Display: 0 - 256 V 

The supply voltage to the throttle sensor is displayed. This signal is used for the throttle sensor output correction.

Brake Clutch Duty Ratio 

1. Display: 0 - 123% 

The duty value of the 2 - 4 brake duty solenoid. The 2 - 4 brake duty solenoid is regulated by the TCM, adjusting the 2 - 4 brake pressure during shifting and relieving from harsh shifting.

Rear Wheel Speed 

1. Display: 0 - 255 km/h (0 - 158 MPH) 

The rear wheel speed is displayed. This signal is used to control the transfer. If the front vehicle speed sensor is malfunctioning, this signal is used as a substitute.

Cruise Control Signal 

1. Display: ON or OFF 

When the cruise control switch is ON, ON is displayed. When OFF, OFF is displayed.

ABS Signal 

1. Display: ON or OFF 

When the ABS function is active, ON is displayed. When inactive, OFF is displayed.

Stop Light Signal 

1. Display: ON or OFF 

When the brake pedal is depressed, ON is displayed. When released, OFF is displayed.

1st, 2nd, 3rd, D, R, Range Signal 

1. Display: ON or OFF 

When the switch for each range is ON, ON is displayed.

2-4 Brake Timing Sol. 

1. Display: ON or OFF 

When the 2-4 brake timing solenoid is ON, ON displayed. When OFF, OFF is displayed. The 2-4 brake timing solenoid is regulated by the TCM, controlling the release timing of the 2-4 brake.

Low Clutch Timing Sol. 

1. Display: ON or OFF 

When the low clutch timing solenoid is ON, ON is displayed. When OFF, OFF is displayed. The low clutch timing solenoid is regulated by the TCM, controlling the release timing of the low clutch.

Shift Solenoid #1, #2 

1. Display: ON or OFF 

When the solenoid valve is ON, ON is displayed. When OFF, OFF is displayed. By combining No. 1 and No. 2 solenoids, the shifting mechanism is controlled.

P Range 

1. Display: ON or OFF 

When the shift lever stays in P range, ON is displayed. When not in P range, OFF is displayed.

N Range 

1. Display: ON or OFF 

When the shift lever stays in N range, ON is displayed. When not in N range, OFF is displayed.

Torque Control Signal #1, #2 

1. Display: ON or OFF 

When the torque down signal exists, ON is displayed. When it does not exist, OFF is displayed.

Torque Permission Signal 

1. Display: ON or OFF 

The signal which notifies whether or not torque down is possible is displayed. This signal is transmitted from the ECU in response to a torque down signal from the TCU. When torque down is prohibited, ON is displayed. When permitted, OFF is displayed.
