Chapter 9 Hyundai

This chapter contains information for testing Hyundai vehicles with the Asian Import Vehicle Communication Software (VCS). The following Hyundai systems may be available for testing:

• Engine• Transmission• Antilock Brake System (ABS)• Airbag (SRS)

9.1 Testing Engine, Transmission, ABS, and SRS SystemsHyundai engine, transmission, and airbag (SRS) testing includes:

• “Code Reading Connectors and Locations” on page 91• “Clearing Codes” on page 93• “Actuator Tests” on page 93

9.1.1 Code Reading Connectors and LocationsRefer to Figure 9-1 below and Table 9-1 on page 92 Hyundai diagnostic connector locations and adapter usage information.

z To read codes from 1995 and earlier vehicles:

• Use the HYUN-2 adapter (Figure 9-2).

z To read codes from most 1996 and later vehicles:

• Use the OBD-II adapter with the specified Personality Key™ device (Figure 9-3 on page 93).

NOTE:i Always use the Personality Key™ device specified in the on-screen instructions.

9.1.2 Clearing CodesMost 1988 and later Hyundai models let you clear trouble codes from PCM memory through the scan tool Exit menu selection CLEAR ECM CODES (Figure 9-4).

Figure 9-4 CLEAR ECM CODES selection

When codes are cleared, the scan tool returns to the previous test mode, and the NO CODES PRESENT message displays to indicate codes are cleared.

If code clearing fails for any reason, the previous codes display at the top of the data list when you return to CODES & DATA. If this happens, repeat code clearing.

9.1.3 Actuator TestsThe ACTUATOR TESTS selection is available from the MAIN MENU (Figure 9-5) for most pre-OBD-II models. All actuator tests are key-on, engine-off tests, except for the injector and timing tests which are explained in “Injector Tests (Engine Running Only)” on page 95.

Selecting ACTUATOR TESTS for these vehicles displays a list of available tests. The list of actuator tests displays similar to Figure 9-6. The available tests vary by year and model.

Figure 9-6 Complete list of Chrysler Imports actuator tests

During testing, monitor the selected actuator with a voltmeter, ammeter, or by listening for actuator activation. A completed test does not mean that the actuator was activated. The scan tool only monitors the engine control module (ECM) commands to the actuator.

When an actuator test is selected, the scan tool commands the ECM to activate the selected actuator (Figure 9-7).

Figure 9-7 Sample actuator test initiated

Approximately 5 seconds later, the ECM deactivates the actuator (Figure 9-8).

Figure 9-8 Sample actuator test complete

NOTE:i All actuator tests except for injector tests must be performed with the key on and engine off

(KOEO). If you select a KOEO test with the engine running, a screen like Figure 9-9 displays.

Injector Tests (Engine Running Only)

The injector tests available from the actuator test menu are performed with the key on and engine running (KOER) and are available on most pre-OBD-II vehicles.

The number of injector tests available varies by the number of cylinders and type of fuel-injection system (a 4-cylinder MPI system has four tests; a six cylinder system has six).

When you select an injector test, the scan tool commands the ECM to disable the selected injector (Figure 9-10).

Figure 9-10 Sample injector test initiated

About 5 seconds later, the ECM stops the test and the injector is re-enabled (Figure 9-11).
