TROUBLE DIAGNOSIS
OK or NG
OK >> GO TO 12.
NG-1 >> If the voltage is approx. 5 V when blower motor is ON: Replace unified meter and A/C amp.
NG-2 >> If the voltage is approx. 0 V when blower motor is OFF: Replace BCM.
12.CHECK CAN COMMUNICATION
Check CAN communication. Refer to BCS-13, "
U1000 CAN Communication Circuit".
BCM – ECM
 ECM – IPDM E/R
 ECM – Unified meter and A/C amp.
OK or NG
OK >> Replace ECM
NG >> Repair or replace malfunctioning part(s).
COMPONENT INSPECTION
Refrigerant Pressure Sensor
The refrigerant pressure sensor is attached to the condenser.
Make sure that the A/C refrigerant pressure and the sensor output
voltage are within the specified r ange as shown in the A/C operating
condition figure. Refer to EC-581
(VQ35DE) or EC-1177 (VK45DE).
