Input/Output Signal Chart
| Sensor | Input signal to ECM | ECM function | Actuator |
|---|---|---|---|
| Crankshaft position sensor (POS) Camshaft position sensor (PHASE) |
Engine speed * 1 | Cooling fan control | IPDM E/R ↓ Cooling fan relay ↓ Cooling fan motor |
| Engine coolant temperature sensor | Engine coolant temperature | ||
| Refrigerant pressure sensor | Refrigerant pressure | ||
| Battery | Battery voltage * 1 | ||
| Combination meter | Vehicle speed * 2 | ||
| BCM | Air conditioner ON signal*2 |
*1: The ECM determines the start signal status by the signals of engine speed and battery voltage.
*2: This signal is sent to ECM via the CAN communication line.
