OUT-OF-SERVICE CONDITIONS DESCRIPTION Code Key 21: New & Retread Tire Out-of-Service Conditions was developed for tire manufacturers as a means of coding out-of-service conditions as determined by manufacturer/laboratory failure analysis. It is not meant to replace related codes identified for use by technicians in Code Key 18: Technician Failure Code, or Code Key 82: Operator Vehicle/Equipment Condition Report. Code Key 21 has two codes per condition, a two-character alpha code or an alternative four-digit numeric code. Code Key 21 was introduced with the release of VMRS 2000™ Version 1.05. NOTE: In release of VMRS that preceded VMRS 2000™, Code Key 21 was used redundantly to denote a vehicle group/system. The information once contained in Code Key 21 was assigned to VMRS 2000™ Code Key 31 in 1997.
