Hint:
The standard normal voltage between each pair of ecm terminals is shown in the table below. The appropriate conditions for checking each pair of terminals are also indicated. The result of checks should be compared with the standard normal voltage for that pair of terminals, displayed in the specified condition column. The illustration above can be used as a reference to identify the ecm terminal locations.
Hint:
*: The ecm terminal voltage is constant regardless of the output voltage from the sensor.

Compressor solenoid circuit (2005/11-2006/01)
Description
In this circuit, the compressor receives a refrigerant compression demand
signal from the air conditioning
amplifier. Based on this signal, the compressor changes the degree of
refrigerant compression.
