Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.

3. Check harness continuity between fuel rail pressure sensor terminal 3 and ECM terminal 68.
Refer to Wiring Diagram.
4. Also check harness for short to ground and short to power.
OK or NG
OK >> GO TO 4.
NG >> Repair open circuit or short to ground or short to power in harness or connectors.
4. CHECK FUEL RAIL PRESSURE SENSOR INPUT SIGNAL CIRCUIT FOR OPEN AND SHORT
1. Check harness continuity between ECM terminals 48, 49 and fuel rail pressure sensor terminal 2.
Refer to Wiring Diagram.
2. Also check harness for short to ground and short to power.
OK or NG
OK >> GO TO 4.
NG >> Repair open circuit or short to ground or short to power in harness connectors.
5. CHECK FUEL RAIL PRESSURE SENSOR
Refer to EC-1471, "
Component Inspection" .
OK or NG
OK >> GO TO 6.
NG >> Replace fuel rail.

Component InspectionEBS011ZR
FUEL RAIL PRESSURE SENSOR
1. Reconnect harness connector disconnected.
2. Start engine and warm it up to normal operating temperature.
3. Check voltage between ECM terminals 48, 49 (Fuel rail pres-
sure sensor signal) and ground under the following conditions.
4. If the voltage is out of specification, disconnect fuel rail pressure
sensor harness connector and connect it again. Then repeat
above check.
5. If NG, replace fuel rail.

System DescriptionEBS01205
COOLING FAN CONTROL
*: These signals are sent to the ECM through CAN communication line.
The ECM controls the cooling fan corresponding to the vehicle speed, engine coolant temperature, air condi-
tioner ON signal. The control system has 3-step control [HIGH/LOW/OFF].
