Multi-use Tester, Installed:

PURPOSE
The multi-use tester is a diagnostic read-out box designed to gain access to the on-board diagnostics that are found on Hyundai-built cars and trucks.

- Reads the system performance information that is stored in the vehicle system controllers.
- Displays the fault messages that have been stored in the various system controller memories.
- Allows the technician to run tests of computer-controlled vehicle systems.
- Along with the test instructions in these sections, leads the technician through the diagnostic procedures.

NOTE: There are diagnostic read-out boxes available from other manufacturers that can be used on Hyundai vehicles. However, the diagnostic test procedures included in these sections were designed specifically for use with the 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.
