•Constant speed mode

[Figure 10-40-31] shows the connection diagram for constant speed mode. Do not connect the indicator lamp power supply to the IGNSW (E7) terminal.Turning current from the APP-IP terminal to the IGNSW terminal may cause the EECU power supply to not shutdown.

The indicator lamp can be connected to the APP-OP2 (E2) terminal optionally, but in this case the coolant temperature alarm indication and block heater control cannot be done [See "Terminal assignment" on page 10-40-51].

Do not connect the indicator lamp power supply to IGNSW terminal

[Figure 10-40-32] shows the operation timing for constant speed mode. The speed selection enable switch (E6) is available in two types: toggle and momentary.

Note:The type of the speed selection enable switch: APP-IP6 (toggle or momentary) is mapped. As a momentary switch involves the possibility of a fluctuation in engine speed if the E-ECU is reset, it is recommended to use a toggle switch.

The input voltage from the accelerator sensor (or the input value through CAN communication) is not depended during the constant speed mode in operation, and the target speed is fixed.

The speed of constant speed mode of speed1 switch: APP-IP3 and speed2 switch: APP-IP4 can be selected from (1) speed is set to a specified value1 (standard: 1800min-1), (2) speed is set to a specified value2 (standard: 1500min-1), (3) low idling, and (4) high idling [See "Terminal assignment" on page 10-40-51].

The speed of specified value1 and value2 can be changed (optional).

•Constant deceleration mode

[Figure 10-40-33] shows the connection diagram for constant deceleration. Do not connect the indicator lamp power supply to the IGNSW (E7) terminal.Turning current from the APP-IP terminal to the IGNSW terminal may cause the EECU power supply to not shutdown.

The indicator lamp can be connected to the APP-OP2 (E2) terminal optionally, but in this case the coolant temperature alarm indication and block heater control cannot be done [See "Terminal assignment" on page 10-40-51].

3: Constant deceleration mode (momentary SW operation) selection enable APP-IP6

Note:The type of the speed selection enable switch: APP-IP6 (toggle or momentary) is mapped. As a momentary switch involves the possibility of a fluctuation in engine speed if the E-ECU is reset, it is recommended to use a toggle switch.

As shown in [Figure 10-40-35] the engine target speed in constant deceleration operation is decelerated [See "Speed selection" on page 10-40-30] for the input voltage from the accelerator sensor (or the input value through CAN communication).

The before-mentioned indicator lamp (APP-OP2) isn’t illuminated even in deceleration operation when the target speed is below the deceleration start speed.

Figure 10-40-35

The deceleration ratio of constant deceleration in the APP-IP3 condition can be selected from (1) deceleration ratio1 (standard: 85%), and (2) deceleration ratio2 (standard: 70%).(Speed2 switch is: APP-IP4=OFF [See "Speed selection" on page 10-40-30] (beginning of this part).

The speed of deceleration ratio1, deceleration ratio2, and deceleration start speed (standard: 1500min-1) can be changed (optional).

•Auto deceleration mode

[Figure 10-40-36] shows the connection diagram for auto deceleration mode. The indicator lamp is connected to illuminate when the auto deceleration is permitted. There is no influence in control action even if it’s omitted.

Deceleration permission switch: when APP-IP6=ON, operation oil pressure switch: APP-IP4=OFF (in non-operational condition) is continued over 4s, the auto deceleration is affected and the engine target speed is fixed without depending on the accelerator sensor input voltage (or the input value through CAN communication).

The speed of auto deceleration of speed1 switch: in the APP-IP3 condition can be selected from (1) constant speed1 (standard: 1800min-1), or (2) low idling [See "Speed selection" on page 10-40-30] (beginning of this part).

The speed of constant speed11 in common use with constant speed mode can be changed. The duration of operation oil pressure switch OFF (standard: 4s) can also be changed (optional).
