PARTIAL REPAIR: COMPRESSOR FIELD COIL ASSEMBLY
INSPECTION AND REPLACEMENT

 NOTICE
This bulletin has been revised to include additional information. New/revised sections of this
bulletin are indicated by a black bar in the margin area.
This bulletin provides information regarding A/C Compressor Field Coil Assembly inspection and replacement
on some 2017-2018MY Forte (YDm) and 2019-2023MY Forte (BDm) vehicles. Follow the diagnostic
procedures in this bulletin to isolate air conditioning compressor faults such as open field coil circuit. Kia has
made the Field Coil/Bolt available as a serviceable item.

 NOTICE
Replacement of the complete compressor assembly for this concern is not required. Warranty claims
submitted for AC compressor replacement, when only the field coil is defective will be subject to
chargeback.

A printed copy is for reference only; publication information can be updated at any time.
Always refer to KGIS for the latest information. After logging in kdealer.com, the newest technical
publications are listed in ‘Service Releases’ and has the latest service information that has been released.

PARTIAL REPAIR: COMPRESSOR FIELD COIL ASSEMBLY
INSPECTION AND REPLACEMENT

Inspection Procedure: Field Coil Diagnosis (A/C Inoperative)
1.

Start the 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.

If the resistance is less / more than the specification, replace the field coil assembly following the service
procedure in this bulletin. Refer to page 3.

5.

If battery voltage is not present, check the A/C fuse for an open circuit, otherwise diagnose the electrical
circuit and confirm pressure switch is operational.

INSPECTION AND REPLACEMENT

SUBJECT:

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.
