Cruise Control woes...

[Porkchop]

I did do a search for this and nothing came up as to an appropriate fix, I was also in communication with a SHO guru on this board and he is stumped.

Ok, my problem is: After I did my brake booster changeout and some rear suspension work my cruise control doesn't work. The light on the dash comes on when you turn the system on, but when you go to puch "set" it doesn't set.

Things I've checked:

• <font size="2" face="Verdana, Helvetica, sans-serif">No vaccumm lines on the box in engine, so no vac. line leaks.
  
  it can't be the clockspring because all the systems that are tied in with that are all functioning normally
  
  Fuse under dash is fine
  
  connector is free of debris and not cracked

<font size="2" face="Verdana, Helvetica, sans-serif">
The only thing going into the CC unit is the electrical connector and I don't know what wire goes to what shrug

Im totally out of ideas on this one, can anyone help me out?

Porkchop,

The clockspring contains connections for the airbag, the horn, and the cruise control. The wires are contained in a ribbonlike strip that winds and unwinds as you turn the steering wheel, thus the title "clockspring".

The wires to each of the aformentioned items are separate and distinct. There are wires for each item and one may fail without affecting the others.

There is a self test that can be done to pull codes relative to the cruise control by using a volt meter with the usual pos. and neg. leads, and a jumper wire.

If you're interested and do not have access to a Helm Service Manual, I'll post it for you. rangerj

Please identify the vehicle by year and transmission.

OK tell us the Guru that you spoke with.. So that way we can direct very simple questions that way.

Hey you owe me 25.00, someone just reminded me last night

Check to make sure you reconnected the deactivator switch which should be on the bottom of the master cyl.

Ranger J - I have the factory service CD, but I don't think that it has it. If you would - would you post it, it would be something for me to check tomm.

Project - 96 SLO AX4N Tranny

Heh Kirk - it was a self named guru ... Mike from Midwest. I havn't been able to hook up that antenna, and I still have it. I havn't been up near the shop to give it back to you, I was even debating putting it up on ebay and giving you the proceeds, but havn't gotten that far.

Chris - Yeah I did reconnect that after I finished, but I will double check if its TRULY in there or not.

Thanks for the input - Kirk shoot me an e-mail about the antenna, I might just mail it back to you.

Porkrind, since you have the CD, go to section 10-3 of the shop manual (Speed Control System—Electronic), look up Pinpoint Test A and follow the various procedures listed. It would help to have a DMM (digital multimeter).

Porkchop,

Look in the section of the manual for "Speed Control System with Resume" under "testing" in that section. I am posting the information from my 1990 Shop Manual and do not know for sure if the information applies to your model year.

I do know I have done this to other model years, for both "SLO" Taurus and Sable models, but I do not recall doing it on a 96. I do not recall any major changes to this system, but be forewarned that this is my disclaimer.

Back by the firewall on the passenger side is the "Self Test Input" (STI) connector (single wire connector, and The "Self Test Connector" (STC), the one that looks like a house in profile. These are the same connectors where you jumper to pull the ECU codes in re. engine sensors.

Look at the STC with the flat side down, the long slope (roof) to the left, and the short slope to the right. The top row has 2 "pins", from left to right 1 and 2. Jumper the one on the right, #2, to the STI (single wire).

The bottom row of "pins", from left to right, are #3, 4, 5, and 6. Set your analog (swing needle volt meter) volt meter to 0 to 15 volts (or 0-20, or 0-25). The point is you are going to be looking at battery voltage which is typically in the 13.8 to 14.2 volt range.

The positive lead goes to the positive battery terminal. The negative lead goes to pin #4 (second from the left on the bottom row).

OK, thats the hook up. Now for the tests.

Key On Engine Off (KOEO) If there are codes stored the needle will swing (sweep). The system will go through a "Quick Test" and trigger the various components.

When this is done there will be a pause, then the sweeps will begin. Count the needle sweeps. There will be a two second pause between digits and a 1/2 second pause between sweeps. Eg.two sweeps -pause- three sweeps = code 23. Easy huh?

The Key On Engine Running (KOER) test is performed at normal operating temperature, other than that the process is the same.

It would be a good idea to take the vehicle for a ride to bring it up to temperature, and to try your system so that the failure can be "recorded" in the computer, that is set codes.

Please note that not all problems with the system will cause codes to be set, just like the ECU will not code for a bad spark plug.

Give it a try and see if you get any codes, but before you do see if you can verify that the system is the same as it was in 1990, or at least that it can be tested the same way. eek!

If you get codes let us know. Then we can determine what the codes tell us, and where to look for the malfunction. shrug rangerj

Chris, Ranger -

I will check with the CD tonight im going to try my best to try the KOER, KOEO tests and everything else tomm and let you know what happened.

Thanks guys beer

SHOooo:

You mean the Discomboobulator ****....

Lambchop, you could always ask SHOooooooo to track it down, he likes that stuff.

Plus I have no idea where that antenna has been recently.. You keep it down there..

 

[Porkchop]

well I don't need the antenna anymore ...

and its not been where your thinking thats for sure...

when I get back from my trip I will throw it up on ebay for ya Kirk and give you the proceeds

porkrind and lambchop


these are great
