INSPECTION

PROCEDURE

1. INSPECT COMPRESSOR AND MAGNETIC CLUTCH (A/C LOCK SENSOR)

(a) Measure the resistance according to the value(s) in the table below.

Standard Resistance:

Tester Connection	Condition	Specified Condition
1 - 2	20°C (68°F)	160 to 320 Ω

If the resistance is not as specified, replace the compressor and magnetic clutch.

2. INSPECT COMPRESSOR AND MAGNETIC CLUTCH (A/C COMPRESSOR SOLENOID)

(a) Measure the resistance according to the value(s) in the table below.

Standard Resistance:

Tester Connection	Condition	Specified Condition
2 - 1	20°C (68°F)	10 to 11 Ω

If the resistance is not as specified, replace the compressor and magnetic clutch.

3. INSPECT COMPRESSOR AND MAGNETIC CLUTCH

(a) Disconnect the connector from the compressor and magnetic clutch.

(b) Disconnect the connector from the magnetic clutch.

Standard Resistance:

Tester Connection	Condition	Specified Condition
A-3 - B-1	Always	Below 1 Ω
A-3 - Body ground	Always	10 kΩ or higher

If the resistance is not as specified, replace the compressor and magnetic clutch.

4. INSPECT MAGNETIC CLUTCH

(a) Measure the resistance according to the value(s) in the table below.

Standard Resistance:

Tester Connection	Condition	Specified Condition
1 - Body ground	20°C (68°F)	3.8 to 4.2 Ω

If the resistance is not as specified, replace the magnetic clutch.

(b) When connector terminal 1 is connected to the positive (+) battery terminal, check that the following occurs: 1) the magnetic clutch's operating sound can be heard, and 2) the magnetic clutch's hub and rotor lock.

OK:

The magnetic clutch's operating sound can be heard.

The magnetic clutch's hub and rotor lock.

If the result is not as specified, replace the magnetic clutch.
