leads as shown.
9-PIN
In glovebox, next to latch. Use MULTI-1 adapter and connect colored leads as
shown, using black terminal converters.
2-PIN

NOTE:
Most OBD-II vehicles have 16-pin and 12-pin connectors and use the MITSU-1 adapter
connected through the OBD-II adapter. The MITSU-1 lead with the 12-pin connector is not
connected on all vehicles. Follow instructions on the scan tool for correct hookup.
To read SRS codes from most 1994 and earlier vehicles:
• Use the HYUN-2 adapter and red terminal converters (Figure 13-5

Read codes on:
A/T oil temp lamp or neutral indicator lamp
Start codes by:
16-pin OBD-II data link connector (Figure 13-14 on page 150): jump pin 1 to
ground.
When done:
Remove the jumper wire and clear codes.
Code display cycle repeats as long as system is in a diagnostic state.
13.1.3 ABS Manual Code Reading
Mitsubishi models transmit Type 11 ABS codes, see Figure 13-7 below and Table 13-4 on
page 148.

Pattern:

Read codes on:

Start codes by:
16-pin OBD-II DLC (Figure 13-14 on page 150): jump pin 1 to ground; or connect
an analog meter across pins 4 or 5 to pin 8.
12-pin diagnostic connector (Figure 13-14 on page 150): connect an analog
meter across pins 4 and 12.
When done:
Remove the jumper wire and clear codes.
Code display cycle repeats as long as system is in a diagnostic state. A battery surge that causes the
ABS system to fail may cause Code 16 to set.
13.1.4 Codes & Data (Slow)
Some 1988 and later models with the 3.0L SOHC V6 engine transmit data at a 63 baud rate.
The MAIN MENU for these vehicles displays CODES & DATA(SLOW) (Figure 13-8).

13.1.5 Clearing Codes
Most 1988 and later Mitsubishi models let you clear trouble codes from PCM memory through
the scan tool. Select CLEAR ECM CODES from the Exit menu (Figure 13-9).

When codes are cleared, the scan tool returns to the previous test mode, and NO CODES
PRESENT displays to indicate that codes are cleared.
If code clearing fails for any reason, the previous codes reappear at the top of the data list. If
this happens, repeat the code clearing procedure.
13.1.6 Actuator Tests
Most pre-OBD-II and all 2002–03 OBD-II models have the ACTUATOR TESTS selection on
the MAIN MENU (Figure 13-10). All actuator tests, except injector and timing tests (see
“Injector Tests (Engine Running Only)” on page 150,) are key-on, engine-off (KOEO) tests.

Figure 13-11 Complete list of Chrysler Imports actuator tests
During testing, monitor the selected actuator with a multimeter 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.

Testing Engine, Transmission, ABS, and SRS Systems
When you select an actuator test, the scan tool commands the ECM to activate the selected
actuator (Figure 13-12).

Approximately 5 seconds later, the ECM deactivates the actuator (Figure 13-13).

All actuator tests except for injector tests must be performed with the key on and engine off
(KOEO). Select a KOEO test with the engine running and a screen like Figure 13-14 displays.

Injector Tests (Engine Running Only)
Injector tests are available from the actuator test menu on most pre-OBD-II vehicles. These
tests are performed with the key on and engine running (KOER). The number of injector tests
available varies, 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 13-15).
DISABLING INJECTOR #1
FOR 5 SECONDS.

About 5 seconds later, the ECM stops the test and re-enables the injector (Figure 13-16).
