1996 Plymouth Voyager cruise control indicator light

OK first off I do not email to private emails so you reply to here so I can have all the dialog to look over so I can make sure nothing is missed. Secondly I need to know that you are comfortable enough doing some tests with a digital multi meter. As for your question no fuse dedicated to the cruise control but there is a test that can be done and it could a bit to get it all done to determine what the problem is. It is 19 steps and we will take it in sections ok. So get back to me with some information first what engine do you have 3.0 to 3.3 or 3.8 ltr and is this a SE model or not? We will take it from there. Is the cruise working and the light just don't come on or is the cruise inoperative? Thank you.

Well you need a digital multi meter. It don't have to be a 100 dollar meter either just a simple 20 dollar one it fine but with out it I can not help you as you need to do some tests and I need to know what voltages and ohms will be. Here is a pic of a inexpensive meter like I said it don't need to be a high dollar one, you can find them at your local parts or hardware stores.

Sorry I just got back from vacation thats why it took a bit to get back to you. Now that you have a digital meter we can do some tests. Now first make sure you have a brake light if the brake lights don't work neither will the cruise. Now if that works then you need to find the speed servo near the battery and unplug the 4 pin connector now connect you meter between pin 3 and ground and set on the 20 volt scale and turn key on engine off and press the cruise on button what is the voltage? Here is pic of the connector get back to me with what you find as this determines what direction we go from there.

Ok first you need to redo the test and set you meter on the DC Volt scale set on 20 volt or 12 volt if you have that setting. Now as for the abs light when did it come on? How long has it been on? Get back to me on that with abs light on the cruise will not be allowed to work.

Ok the wire colors should be the same. Now is this a regular voyager or grand and what is the production date on the door? I will double check the test and make sure nothing changes. Now lets do a switch test. You will need to pull the cruise switches off and then do the following test. You will do an ohms test so set you meter on ohms and then on the on/off switch check to continuity there should be none then press the on/off switch and it should read 0 to.5 ohm. If this checkes out then I need you to do check for diagnostic codes from you car. Now to do this is very simply you don't even need a code reader. You simply turn the key on then off, on, off then on within 5 seconds now leaving the key on on the last turn you engine light should go out then start to flash. It will flash then pause then flash again then before going to the next number it will pause longer then flash and pause and flash again. For example a code 55 and code 34 will be as such. It will flash 5 times pause then flash 5 times then it pause longer and then flash 3 times pause and then 4 times. It will do this till it starts over then turn the key off. Let me know what codes you find and I will see if any relate to you problems.

Ok lets check the first test again ok. Unplug it again and and put the red or + from you meter in term number 3 and the black or - to a good ground. Now turn the key on engine off and then push the on/off switch and tell me what the voltage is. It should read 10 or more volts +10 or more. Let me know what you find as this will answer if the switches on the wheel is working. If this is ok then turn the key off. Now I need you to set you meter on ohms and check the ohms between term number 4 and ground. Hook the red wire or + to the term 4 and the black or - to ground, let me know what ohms you find. If this is ok then we will do a pin test on the pcm and then test the speed sensor.
As for the codes you found they do not have much meaning as the car was not running and none of them have anything to do with the cruise.

Sorry I ment term number 3. So you set you meter on ohms and 200 or 2000 setting is fine and then connect the red wire from your meter to term 4 and the black wire from you meter to ground and make sure that you have more then 5 ohms if it is less then you need to check the wire for any possible breaks in it. If this checks out then plug the connector back in and go to the brake light switch at the brake pedal in the car. Now you will unplug it and check term 3 it should be a yellow wire with a red stripe. You will check voltage here so what you will do it hook up your meter and then turn key on engine off and push the on/off button and you should get battery voltage there 10 or more volts. Let me know what you find here as this determins where we go from here. I am sorry it is taking a bit to figure this out but it is a little slower doing it over the net, so just be patient as I am here till it works.

Ok it looks like you may have a bad vehicle speed sensor (VSS). Now you will need to unplug the VSS you may have a 2 or a 3 wire connector either way you will check ohms between the VSS and the transmission control module (TCM). So you will hook you meter between term 1 on the VSS and term 13 on the TCM. If resistance is less the 5 ohms then replaced the VSS. The VSS is located on the transmission on the passanger back side of it. The TCM is located under the hood near the windshield washer reservior. Again I have included pics the first is of the two possible VSS connectors and the other is of the TCM connector.
