Mitsubishi Pajero Mini Junior AISIN MR195407 MR195408 and MR246350 Daihatsu 89530-87507 Transmission Control Unit Pinouts, There may be others but these are the ones I I see often.
This is a Work in Progress, If anyone has the missing information let me know. (Do you need Your Pajero TCU Serviced Click Here For Info)
Need to do,
Solenoid Activation Per Gear?
Engine Pulse Type Magnetic, Hall, other. Info for Shift Points and Pulse Data.
Speed Pulse Info For Shift Points Is Sensor Inductive or Hall Effect?
Figure out Pin 12
Connector A | 12 Pin
O Pin 1 Black/White 1st Shift Solenoid
O Pin 2 Black/Blue 2nd Shift Solenoid
O Pin 3 Blue/White 3rd Shift Solenoid
Pin 4 NC
Pin 5 NC
I Pin 6 Green/White TPS +0.60V to +4V (480 Ohm to 1.3K Ohm)
Pin 7 Red/Green (IGN) 12V DC Ignition On
Pin 8 NC
Pin 9 Black GND
Pin 10 Black GND
Pin 11 NC
*Pin 12 Green/Light Green (5v Unknown Function Possibly The Pressure Relief Valve Input or MAP??)
Connector B | 16 Pin
Pin 1 NC
Pin 2 NC
I Pin 3 Pink Engine Speed “Need Pulse Info” Assume Crank Position Sensor? May be other Source Injection System?
Pin 4 NC
Pin 5 NC
Pin 6 NC
I Pin 7 Yellow/Green 2 Position On Shifter +12V Applied If Selected
I Pin 8 Green/Red D Position On Shifter +12V Applied If Selected
Pin 9 NC
I Pin 10 Black/Blue Speed Sensor In (Hall Square Wave / Inductive?)
O Pin 11 White/Blue Speed Sensor Out (Hall Square Wave / Inductive?)
Pin 12 NC
Pin 13 NC
Pin 14 NC
I Pin 15 Yellow/Red L Position On Shifter +12V Applied If Selected
I Pin 16 Green Black “Brake/Stop” (Unknown Function) or NC On Most Units
Notes:
“O or I” is Output or Input
Solenoid Resistance 12 Ohm 1 Watt Solenoid’s.
Possible Operation Theory (Soon)
3 Gears, 3 Solenoids.
Gear number 1
- Solenoid 1 on/off
- Solenoid 2 on/off
- Solenoid 3 on/off
Gear number 2
- Solenoid 1 on/off
- Solenoid 2 on/off
- Solenoid 3 on/off
Gear number 3
- Solenoid 1 on/off
- Solenoid 2 on/off
- Solenoid 3 on/off
