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).

9.1.2 Clearing Codes
Most 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).

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 Tests
The 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.

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).

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

NOTE:
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).
DISABLING INJECTOR #1
FOR 5 SECONDS.

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