Reading Input and Output Signals

Reading input and output signals

Using this function the values and status of the transmission control module (TCM) input and output signals can be read continuously.
The following parameters can be read off:
- Mode, gear-shift position sensor
- Gear-shift position sensor, position
- Gear-shift position sensor, signal A
- Gear-shift position sensor, signal B
- Gear-shift position sensor, signal C
- Gear-shift position sensor, signal PA
- Mode selector signal, signal MS1
- Mode selector signal, signal MS2
- Mode selector, position
- Mode, mode selector
- Stop (brake) light switch, position
- Kickdown switch, position
- Kickdown position, shifting
- Throttle position (TP) sensor, signal
- Throttle position (TP) sensor, position
- Oil temperature sensor, signal
- Oil temperature
- Battery voltage
- Vehicle speed
- Input speed to transmission
- Engine speed (RPM)
- Load signal from engine control module (ECM).
- Gear in relation to solenoid S1, S2 and SL
- Gear in relation to ratio
- Activating shift solenoid S1
- Shift solenoid S1, position
- Activating shift solenoid S2
- Shift solenoid S2, position
- Activating lock-up solenoid SL
- Lock-up solenoid, position
- System Pressure Solenoid STH, %
- System Pressure Solenoid STH, amperage
- Idle Air Control (IAC), P/N position
- Warning lamp in combined instrument panel
