1.5 CRS Construction
The illustration below is an outline of the CRS. The primary feature of this system is the use of two rails and two EDUs in order to comply with the V-8 engine. When looking into the engine compartment from the driver's seat, the two rails are positioned above the right and left banks (hereafter: right bank rail = "rail RH", left bank rail = "rail LH"). EDU No.1
and No.2 each control four injectors.

3. RAIL
3.1 Outline
Rail RH is provided with a fuel inlet to connect rail RH to rail LH. Rail internal fuel pressure is controlled by a rail pressure sensor (Pc sensor) attached to rail RH, and the engine ECU. In addition, when rail internal pressure becomes abnormally high, a pressure limiter attached to rail LH opens to release excess pressure.

4. INJECTOR

The CRS used in the TOYOTA LANDCRUISER 70 is equipped with eight solenoid injectors with QR codes, as shown in the figure below.

The figure below is an external view of the engine ECU. For details on the connector terminal layout, refer to "8.2 Connector Terminal Layout".
5.3 EDU
The CRS for the TOYOTA LANDCRUISER 70 uses two EDUs (No.1 and No.2). Control of the eight injectors is divided into two systems. EDU No.1 controls cylinders 1, 4, 6, and 7, while EDU No.2 controls cylinders 2, 3, 5, and 8. The following page displays a circuit diagram for one system.

Operation Section
5.4 Sensors
(1) Crankshaft Position Sensor
The crankshaft position sensor is a Magnetic Pick Up (MPU) type sensor. The crankshaft position sensor is attached to the crankshaft timing gear, and detects NE pulses according to the number of timing gear teeth. There are 34 timing gear teeth plus two missing teeth. When the two missing teeth pass the crankshaft position sensor, Top Dead Center
(TDC) is accurately detected due to the pulse change.
Operation Section
1 11
(2) Cylinder Recognition Senor
The cylinder recognition sensor is a Magnetic Pick Up (MPU) type sensor. The cylinder recognition sensor is attached to the camshaft timing gear. When the protrusion on the timing gear (G pulsar) passes the sensor, cylinder recognition is performed according to the pulse change.
(3) Accelerator Position Sensor (Accelerator Pedal Module)
The accelerator position sensor is a hall element type sensor. Accelerator position is converted to an electrical signal that is output to the engine ECU.
Operation Section
1 12
(4) Coolant Temperature Sensor
The coolant temperature sensor detects the temperature of the engine coolant. The coolant sensor contains a builtin thermistor that undergoes changes in resistance according to coolant temperature. The change in coolant temperature is detected using the change in the thermistor resistance value.
5.5 Exhaust Gas Recirculation (EGR) Valve
The EGR valve is a linear solenoid type valve. The amount of EGR valve lift is changed according to signals from the engine ECU, which is used to control the volume of exhaust gas sent to the intake manifold.
Operation Section
1 13
6. FUEL INJECTION CONTROL
6.1 Outline
Fuel injection control can be roughly divided into the following four types of control: 1) Fuel injection quantity control, 2) fuel injection timing control, 3) fuel injection rate control, 4) fuel injection pressure control. Basic control content is identical to that contained in the general edition manual. However, the fuel injection timing control injection patterns is different for the LAND CRUISER 70. The following is an explanation of the injection pattern.
6.2 Injection Pattern
Fuel injection timing is controlled according to the duration the injector is energized. First, main injection timing is determined, followed by timing determinations for pilot injections 1 and 2.
