The above link is to a diagram of your ALDL connector, all you need is a paper clip, straighten out the paper clip and insert one end into the diagnostic test pin and one in the system ground pin (terminals A & B).

Then put the key in the ignition and turn it to the on position but DO NOT start the engine. You will then see the check engine light flash. It will initially start by flashing once, then a pause and then flash twice and it will repeat this three times. That flash sequence indicates 12, which just means the system is operating. Its the flash sequences after that that will give you the code if any are stored.

For instance if it flashes twice, then pauses, then flashes four times, thats code 24. So any flash sequence you get after the initial 12 (flash once, pause, flash twice) you need write those down. Below is a list of diagnostic codes to tell you what the codes mean.

Code 12
1 flash, pause, 2 flashes
Diagnostic: This Code will flash whenever the diagnostic terminal is grounded with the ignition switch turned on and the engine is not running.

Code 13
1 flash, pause 3 flashes
Oxygen sensor voltage stays between 0.35 and 0.55 volts for 30 seconds when the TPS signal was above 0.55 volts. The engine had been running for at least 40 seconds with an engine temperature above 110° F.

Code 14
1 flash, pause, 4 flashes
Coolant temperature sensor signal indicates a temperature of over 284° F for 4 seconds after the engine had been running for at least 10 secondsCoolant Sensor Circuit (high temperature) If the engine is experiencing overheating problems, have those fixed before continuing. Check all wiring and connectors associated with the coolant temperature sensor. Replace the Coolant temperature sensor.

Code 15
1 flash, pause, 5 flashes
Coolant Sensor Circuit (low temperature) Coolant temperature sensor signal indicates a temperature colder than -36° F for at least 4 seconds after the engine had been running for 2 seconds. See above, then check wiring connections at the ECM

Code 16
1 flash, pause, 6 flashes
Charging system voltage was either below 9 volts or above 17 volts for 10 seconds. System High Voltage If the voltage is above 17.1 volts for more than 2 seconds, the Service Engine Soon light will illuminate. Have the charging system checked.

Code 17
1 flash, pause, 7 flashes
PCM did not detect any spark reference pulses within 240 fuel control reference pulses (80 crank revolutions) while engine was running below 1200 RPM. Spark Reference Circuit.

Code 21
2 flashes, pause, 1 flash
Throttle Position Sensor, TPS voltage was above 0.8 volts for 5 seconds when engine was running and air flow was less than 15 gm/sec, or the TPS voltage was over 4.8 volts at any time.

Code 22
2 flashes, pause, 2 flashes
Throttle Position Sensor check TPS adjustment. Replace the TPS sensor. TPS voltage was under 0.2 volts for 4 seconds when the ignition was on. Check for a sticking, or mis-adjusted throttle position sensor.

Code 23
2 flashes, pause, 3 flashes
Inlet air temperature sensor signal showed an air temperature of -29° F for 4 seconds. Manifold Air Temperature. Check the MAT sensor, wiring, and connectors for a possible open circuit. replace the MAT sensor.

Code 24
2 flashes, pause, 4 flashes
Vehicle speed sensor signal showed less than 3 MPH for 2 seconds when engine speed was greater than 3000 RPM and transmission has not been in park or neutral for more than 4 seconds. Or vehicle speed goes from above 18 MPH to 0 in less than 2 seconds without applying brake. This code can only appear when the vehicle is in motion, if it appears when the car is not in motion, ignore it. Check ECM connections, any other problems should be diagnosed by a qualified mechanic.

Code 25
2 flashes, pause, 5 flashes
Inlet air temperature sensor signal showed an air temperature of over 218° F for 5 seconds when vehicle speed was greater than 35 MPH. Check the voltage between the MAT sensor and the ECM. voltage should be above 4 volts.

Code 26
2 flashes, pause, 6 flashes
Quad-Driver sense voltage shows a low voltage when battery voltage should be present, or if the sense voltage shows battery voltage when a low voltage should be present for at least 5 seconds when the engine was running. Have the car checked by a dealer.

Code 27
2 flashes, pause, 7 flashes
2nd gear switch was closed or grounded for 10 seconds when vehicle was in 4th gear, or 2nd or 4th gear switch was open when engine was first started. Gear switch Diagnosis Have the car checked by a dealer.
