REFRIGERANT PRESSURE SENSOR
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.
Diagnostic ProcedureBBS00571
1. CHECK REFRIGERANT PRESSURE SENSOR OVERALL FUNCTION
1. Start engine and warm it up to normal operating temperature.
2. Turn A/C switch and blower fan switch ON.
3. Check voltage between ECM terminal 70 and ground with CON-
SULT-II or tester.
OK or NG
OK >>INSPECTION END
NG >> GO TO 2.
2. CHECK GROUND CONNECTIONS
1. Turn A/C switch and blower fan switch OFF.
2. Turn ignition switch OFF.
3. Loosen and retighten two ground screws on the body.
Refer to EC-457, "
Ground Inspection" .
OK or NG
OK >> GO TO 3.
NG >> Repair or replace ground connections.

by CAN communication line.
Diagnostic ProcedureBBS0056I
1. INSPECTION START
Do you have CONSULT-II?
Ye s o r N o
Yes >> GO TO 2.
No >> GO TO 3.
2. CHECK OVERALL FUNCTION
1. Turn ignition switch OFF.
2. Lift up the vehicle.
3. Start engine and let it idle.
4. Select “VHCL SPEED SE” in “DATA MONITOR” mode with
CONSULT-II.
5. Select “VHCL SPEED SE” indication when rotating wheels with
suitable gear position.
OK or NG
OK >>INSPECTION END
NG >> GO TO 3.
3. CHECK DTC WITH “ABS ACTUATOR AND ELECTRIC UNIT (CONTROL UNIT)”
Refer to BRC-8, "
TROUBLE DIAGNOSIS" or BRC-44, "TROUBLE DIAGNOSIS" .
OK or NG
OK >> GO TO 4.
NG >> Repair or replace.
4. CHECK DTC WITH “UNIFIED METER AND A/C AMP.”
Refer to DI-27, "
UNIFIED METER AND A/C AMP" .
>>INSPECTION END “VHCL SPEED SE” indication should
exceed 10 km/h (6 MPH).
