PURPOSE
The multi-use tester is a diagnostic read-out box used to gain access to the on-board diagnostics.

1. The multi-use tester reads the system performance information that is stored in the vehicle system controllers.
2. The multi-use tester displays the fault messages that have been stored in the various system controller memories.
3. The multi-use tester allows the Technician to run tests of computer-controlled vehicle systems.
4. The multi-use tester, along with the test instructions in these sections, leads the Technician through the diagnostic procedures.


Note: There are other diagnostic read-out boxes that can be used on Hyundai vehicles. The diagnostic test procedures included in these sections were designed specifically for use with Hyundai's multi-use tester diagnostic read-out box. It is assumed that the multi-use tester will be used to perform the procedures in these sections.

OPERATION
The multi-use tester operates by communicating with the controller for the vehicle system being tested.

To perform the diagnostic tests, a program cartridge must be inserted into the multi-use tester. This cartridge serves a similar purpose for the multi-use tester as a diskette does for a personal computer. It contains the diagnostic test program. It must be inserted into the multi-use tester in order to perform the tests in these sections. The power supply cable is attached to the positive terminal of the battery, or the cigarette lighter.
