Keyless Entry Module: Testing and Inspection

NOTE: On EARLY BUILD vehicles, the SKREEM controls the functions of the SKIM and RKE modules. On NORMAL BUILD vehicles, the SKREEM controls the functions of the SKIM, RKE module and TPM system. If diagnosing the TPM, use the DRBIII(R) scan tool to determine if the SKREEM includes TPM system functionality.

For proper diagnosis and testing of the Sentry Key Remote Entry Module (SKREEM), use a DRBIII(R) and refer to the proper Body Diagnostic Procedures information.
