RE:
AC Inoperable and Compressor Fails to Engage
TIN NO.
TIN-21-55-001
AFFECTED VEHICLES: 2022 Outlander
When diagnosing a 2022 OUTLANDER, be aware that the logic of the IPDM (Intelligent Power
Distribution Module) may inhibit power from being applied to the compressor as part of its
self-protection logic. The technology in the IPDM uses a Smart FET (Field Effect Transistor)
to protect the system. Due to this protection system the IPDM will continue to inhibit power
supply to the compressor until the code is cleared in the IPDM.
 When Smart FET integrated in IPDM E/R (Electronic/Relay) turns on, electricity is
supplied to field coil, clutch is pulled to pulley and engages, rotational movement is
transmitted from crankshaft pulley  Drive belt  Clutch Disk  Drive shaft --AC
compressor is operated. When Smart FET turns off, electricity is not supplied to
field coil, and clutch disc is released from pulley. AC compressor is not operated as
a result of IPDM inhibiting power to compressor.
 NOTE: When the IPDM / Smart FET inhibits operation to the compressor, a code will
be stored in the IPDM and will continue to inhibit power from reaching the
compressor clutch until the code is cleared using MUT3 SE.
 When faced with diagnosing a concern where power is not supplied to the AC
compressor:
 Print out the ALL DTC and FFD first for documentation purposes.
 Inspect connectors B62 & B63 for connector tightness and terminal tightness
and apply Stabilant – 22 to the terminals, before resecuring.
 Ensure the AC system is not under charged or over charged.
 CLEAR the codes in the IPDM and retest the system for normal operation.
 Does the compressor clutch now engage after clearing the code?
 YES—No further action is needed and a claim can be placed for diagnosing the
system and repairing the connector.
 NO—Continue diagnosis as per the service manual and contact the TechLine if
needed.
NOTE: Please make sure to adhere to the Warranty Policy and Procedures for any
claims submitted.
