Oil bypass control valve
(OVEV)
CN5[8] Red
CN5[6] Brown
CN5[1] Blue
CN5[3] Orange
CN5[4] Yellow
CN5[2] White
11 ~ 13 V DC
Red-White
46 ± 4 Ω
NOTE) When the elecrtonic
expansion valve is 5 cores
(without brown), substitute
red core for brown core.
Red-Orange
Brown-Yellow
Brown-Blue
White-Orange
92 ± 8 Ω
Yellow-Blue
Compressor clutch 2 (C/P2) CN8[12] White
14.5 ~ 18.5 V DC 4 Ω ± 20 %
NOTE) Be sure to measure
voltage and resistance
between the specified
connector and the ground
(body ground).
Hot gas bypass valve (BV) CN11[1]-[7] Red-Red 200 V AC 1050 Ω
Reversing valve (4PV) CN11[2]-[8] Red-Red 200 V AC 950 Ω
Compressor heaters 1, 2
(C/P H1, 2)
CN11[5]-[11] Yellow-Yellow
200 V AC 1.67 kΩ ± 7 %
NOTE) When measuring resis-
tance at the connector on
the PCB, the measured val-
ue is 1/2 of the actual value
for one compressor heater,
because 2 compressor
heaters are connected to
one connector in parallel.
Electromagnetic compres-
sor capacity valves 1, 2
(C/PV1, 2)
1: CN11[3]-[9] Blue-Blue
200 VAC 1050 Ω
2: CN11[4]-[10]
White-White
