*1 :
Generator generating current value.
*2 :
Refrigerant pressure switch (middle pressure switch) is off.
*3 :
Refrigerant pressure switch (middle pressure switch) is on.
*4 :
Back-up current is the constant flow of current present (for the audio unit, clock, PCM, etc.) when the ignition switch is off and with the ignition key removed.
*5 :
For intensely hot area.
*6 :
The lower limit must be more than 0 A.
*7 :
Turn the following electrical loads on and verify that the voltage reading increases.
