Inspection and Verification
•
DTC B2119 Compressor Failure
Refer to
— The interface adapter assembly (IAA) module
monitors the A/C compressor speed feedback
signal from the A/C inverter motor controller
(IMC) to determine if the A/C compressor is
not operating when it should be. If the IAA
module is commanding 14% duty cycle and
the compressor speed does not increase above
250 rpms for 30 seconds, DTC B2119 is set.
