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].
