ANY BUYING/SELLING IN THIS FORUM WILL RESULT IN AN INSTANT BAN!

Read the rules: http://www.cb7tuner.com/vbb/showthread.php?t=43956

Myself, and the other mods have been very nice and lenient with the rules. We have been deleting threads, and giving out warnings. Some members didn't get the clue and re-posted over and over... Now ANY member buying or selling in this section will be banned... No IF's AND's or BUT's.

Beginner Forum Rules - EVERYBODY read! (old and new members alike!)

Beginners start here. Once you have 30 worthwhile posts (off topic doesn't count) you may post outside of the Beginner forums. Any "whoring" (posting simply to raise your post count) will return your count to 0, or result in a ban.

These are the rules. Read them. Live by them.

1) Absolutely NO flaming! "Flaming" is an outright attack on a member. ALL questions are encouraged to be asked here, no matter how basic. Members with over 30 posts will be subject to a ONE WEEK ban if caught flaming in this forum (and yes, moderators can read deleted posts). Members with under 30 posts will be subject to a ONE DAY ban.

2) Use appropriate language. Racial or sexual slurs will not be tolerated. A ban will be issued at the discretion of the cb7tuner.com staff.

3) No items may be sold in the Beginner forums. Any "for sale" threads will be deleted.

4) Temporarily banned members will be PERMANTLY banned if they are found posting on another account.

The rules can and will be added to. Any updates will be marked in the title.

    Need help with "s" light problem ASAP!

    Hey everyone!,
    For start I just wanted to thank you all who are currently viewing my post and thank you or the help. Here's my problem. Earlier in the year I had problems with the "s" light on the dash being on and the reason was because the positive battery cable and terminal was corroded where they connect. So I used baking soda and water and cleaned it and refined it etc. causing the "s" light to go away for about two months. I've had a hole between the catalytic converter and the rear exhaust pipe(goes to back of the car) and it was loud but at this time the light wasn't on. Pretty much last week the hole got bigger and the catalytic converter dropped. I fixed that with a pipe and an exhaust clamp and some jv weld. The noise is completely gone but now my "s" light on my dashboard is on. I'll start the car and in about 2 seconds it'll flicker on and off at times but will stay on right away. I tried to find the code to see what the problem was, so I jumpered the two wires together and turned the ignition on and the check engine light came on (like normal) although the "s" light didn't blink any code, it just stayed completely solid, not blinking at all. I even tried to unplug the tcu and plug it back in but the light remains on. To me this is unusual. I drove the car again and the light was off but I know it'll turn back on because it's been doing this since I fixed my exhaust. Why is the light solid, how do I fix it and keep it off? I already tried using a different tcu with the same matching numbers and all and no luck. What do I do? Why is the light solid?, and how do I fix it?

    Thank you all,
    Antonio

    The "S" light is indicating a transmission computer error code. It has nothing to do with your catalytic converter.
    See the thread that says "read here first" at the top of this section? Yeah, read that. It will tell you how to read and interpret the code.

      Thank you I was looking for that. The other guides I've found didn't have the "0" so it looks like it's the tcu that's the problem. Instead of buying one, do you know of a link on how to check the tcu for what's wrong with it and how to replace it by any chance? If not its cool, although thank you again for the help!

        Pull up the carpet on the passenger side floor, unbolt the cage, unbolt the TCU (the smaller box you see) and unplug it. Then take it apart and look for burned components.

        If it blinks no code when jumped (and the key is turned to the II position, engine off), then yes, it may very well be the TCU.


        In the future, please refrain from explaining unrelated issues in one long paragraph about the actual problem. I didn't even see that you jumped the service connector because you spent 3 sentences rambling about a catalytic converter.

              Sorry? I was told that the airflow from the exhaust could effect the transmission and it's electronics by a mechanic. I've only had this car for a year. It's my first car. Sorry

                  Find that guy who told you that, smack the shit out of his ass then walk away.

                    Don't ever take your car to that mechanic again.

                      The idea is to replace the capacitors before this happens. Once you have blown components, then the chance of bad resistors are also included. The board could be fried also. I would go to the junkyard, find a good TCU, the replace the capacitors then put in the car. Use good quality caps if you could, with brands like Nichicon, Panasonic. Remember, these are delicate electronic components, you don't want to leave the soldering gun on there too long. You will boil the capacitors and this can damage or shorten the life of the capacitors. So it's important to find a hot enough gun melt the solder on there then remove right away before the boiling occurs.
