PARTIAL REPAIR COMPRESSOR FIELD COIL ASSEMBLY
INSPECTION AND REPLACEMENT
Inspection Procedure: Field Coil Diagnosis (A/C Inoperative)
1. Start Engine. Turn the Air Conditioning (HVAC) to the ‘ON’ position.
2. Verify engagement of the compressor clutch, if the clutch is operational, monitor the
cycling of the compressor clutch and road test for any intermittent conditions. If the
compressor clutch does not engage, verify battery voltage to the field coil circuit or
reference TSB SST040.
3. If battery voltage is present to the compressor clutch circuit, check the field coil
resistance.

Field Coil Inspection Procedure:
Using a Multimeter, check the resistance
reading on the compressor connector,
Pin 1 (left pin).
Pin 1
NOTE: Images of removed compressor are for
reference use only and to provide visibility.
Connect Multimeter as follows:
Red Lead → Pin 1
Black Lead → Ground
Note: The sample reading shows that the
resistance reading is within specification.
Depending on ambient temperature, and
temperature of the field coil, the
resistance of the coil can have a small
variance. Refer to the table on page 2.
