Question; Why do you think the computer needs re-programming?? What is the car doing to lead you in that direction????

"C-Pack" is a short term for "Connector Pack". It is where several wires are all spliced together by a single connector. C-Packs are used for grounds and for communications lines where common lines are used by several computer modules. The wires connecting at the C-Pack can be individually connected or disconnected from the other wires by simply disengaging their respective connectors from the C-Pack. There are probably several of them located around your vehicle. Why are you looking for it?

The computer plug or DLC connector is located under the dash on the drivers side just above where your left leg would be. It is black in color and is a 16 pin connector.

You have to disengage the PCM (computer) wiring harness from the PCM as the PCM is removed from under the dash. The PCM connector is located on the firewall under the hood to the left of the brake booster, you'll see the a large retangular wiring connector (120 wires) with a single bolt in the middle. Unscrew the bolt, go back under the dash to remove the PCM.

Connector is located under the hood...Guru...saailer

The connector, to plug in a scanner, to read the computer is located just under the dashboard edge on the right side of the steering column. I think the computer module is the silver metal box located under the dash attached to the firewall just to the left of the steering column.

Hello veloruss: My name is Roger and I will try to answer your question so you can locate the terminal. You will find the ALDL connector on the right side of the drivers dash in the area of the gas pedal. Locate the white 3 wire connector. you will also see a green 3 wire connector with a single wire connector. Make sure you use the white 3 wire connector.Jump wires 1 and 3 together to obtain the computer codes. Should you need further help please just ask. Please rate the quality of the answer. This way I know the answer was correct. Thank You for using Fix Ya. Roger

if you go to the auto parts store, they may sell a key that jumps out the dlc connector under the dash. the light will blink for the code.#

CLEARING CODES (works for code 52)
1. Only intermittent codes and codes that diagnostic monitor recognizes as being repaired may be cleared from memory. To clear codes, cycle ignition OFF to ON. Observe AIR BAG warning light. AIR BAG warning light will illuminate for 4-8 seconds, and flash fault code.

(Comment) Loosely translated - If you dont have the problem fixed, this wont work. Code 52 should clear with this!

2. Locate air bag diagnostic 2-pin connector.

(Comment) This was a fun one. According to the air bag wiring diagram that I also got from Mitchell, the Airbag Diagnostic Connector is located "Right side of Instrument Panel". The only thing I found immediately to the right of the I/P (between the stereo and Instrument panel) was a black computer with 4 connectors which is NOT what I was looking for. I finally found a blog that mentioned the computer for the air bag computer was behind the right side kick panel. Sure enough....there it was. Attached to the side of the diagnostic computer was a two prong diagnostic connector.

3. Connect a jumper wire between diagnostic connector terminals. Leave jumper wire connected until diagnostic monitor tone sounds (about 5 seconds). Disconnect jumper wire. Fault code is cleared.

This car is actuelly equiped with 2, and it depends on what kind of connection you have. The OBD2 connector is located on the passenger side to the left of the glove box. The other connector which is a round connector is located under the hood on the drivers side next to the abs module.... It will have a round cover over it.
