Bulletin number: SSM 48135
Component: Equipment: appliance: air conditioner
Summary: Some 2013-2020 vehicles equipped with an EVDC air conditioning (A/C) compressor may exhibit poor A/C performance/improper climate function. To support the proper diagnosis of this compressor, the EVDC control valve tester has been provided to each U.S. dealership (339-EVDC100). Ensure the A/C system has a full charge prior to any compressor diagnostics. To support the proper diagnosis of this compressor, the EVDC compressor tool must be used, and the results recorded in the Technician comments field with the warranty claim. This tester will help reduce the potential for misdiagnosis and unnecessary compressor replacement. Refer to the Rotunda catalog for a video and user manual which provide detailed operating instructions.
