Diagnosis system (IPDM E/R)
Power supply and ground circuitRefrigerant pressure sensor
Description
The refrigerant pressure sensor is installed at the condenser of the air
conditioner system. The sensor uses an
electrostatic volume pressure transducer to convert refrigerant pressure to
voltage. The voltage signal is sent
to ECM, and ECM controls cooling fan system.

Headlamp (LO) circuit
Description
The IPDM E/R (intelligent power distribution module engine room) controls the
headlamp low relay based on inputs from the BCM over the CAN communication
lines. When the headlamp low relay is energized, power flows through fuses 51
and 52, located in the IPDM E/R. Power then flows ...
