SECURITY SYSTEM KEYLESS ADAPTER CABLE
This bulletin supersedes TSB # 02-90-001.
DESCRIPTION:
The security system keyless adapter cable (SPX/Kent-Moore P/N 09900-21300) is a special service tool (SST) that is used for programming new keyless entry remote transmitters to the factory security systems. The keyless adapter is used in conjunction with the Hi-Scan Pro (with Hi-Scan SOL Pro Software Version 09-29-03 or newer) and Data Link Connector (DLC) Cable.
SERVICE INFORMATION:
The keyless adapter cable can be used on the following vehicles:

NOTE
^ The 2003 - 2004 MY Tiburon does not need the Keyless Adapter Cable to add keyless entry remotes to the factory security system. Instead, the Hi-Scan Pro connects to the vehicle using only the DLC cable. See page BE-60 in the 2004 MY Tiburon Shop Manual for the latest instructions.
