Data Trouble Code Retrieval for Alpha Engines</span>
With the increasing rate of people wanting to know the process of carrying out their own "code checking" precoedures, I have developed an article which will tell you step by step, what to do when trying to eliminate problems, using the on board diagnostic system.
Data Link connectors:
Accent 95-99 - above the right most switch panel
Accent 00-Current - below the lower dash shroud
Getz - below the lower dash shroud
Data Link connector configuration:

Data Trouble Code Retrieval (using M alfunction I ndicator L amp):
1. Ignition switch on (do not start)
2. Ground the L-wire (bridge No. 15 pin and No. 4 pin) in the Data Link Connector for 2.5-7 seconds.
3. If there is no fault, code "4444" will be indicated.
4. Each code is repeated infinitely until the next step is ordered.
5. To order the next code to apper, you are required to ground the L-wire again for 2.5-7seconds, after that the next code follows.
The last output consists of the code for end of "code output" which is "3333". After grounding the L-wire again for 2.5-7 seconds, the diagnostic mode is left.
Remember: There will always be four digits in each code output.

Remember: These are only guidelines to aid you in your diagnosis. They will not provide a definite answer as to what component you should replace, but moreso, identify in which area you are experiencing problems.
I will personally hold no responsibility for any failures that may occur to user carelessness!
<span style=\'color:red\'>Actuation Test
There is also an actuation test which can be carried out in order for you to determine whether your actuators are operating correctly.
Actuator Control Sequence Procedure
1. The L-wire (No. 15 pin) in the data link connector has to be grounded before turning the ignition key on (DO NOT START).
2. Turn the ignition key on (DO NOT START) and then disconnect the grounded wire from pin No. 15, then the actuator activation sequence will begin, starting from the fuel pump relay.
NOTE: Each actuator will be stopped after activating 6 times
3. Once the actuator has activated 6 times, you will then be required to ground the No. 15 pin again to follow on to the next actuator in the sequence, which will be listed below:
Test Item__________________Fault Code
1. Evap can. purge valve solenoid_______________1322
2. ISC vAlve solenoid_________________________1321
3. No. 2 injector _____________________________1315
4. No. 3 injector _____________________________1314
5. No. 4 injector _____________________________1313
6. No. 1 injector _____________________________1312
4. If the actuator responds normally, code "4444" (No Fault Code) will be indicated by the MIL.
If there is any faults, the relevant trouble code will be displayed via the MIL.
