I set the cruise control and it operates just fine for about two minutes and then shuts down as if it was cancelled. I do this for a couple of times and then it finally just quits working. the dashboard switch has a green indicator light that remains on but the cruise no longer works.
After a while (a few days) it works again. When I took it to the dealer they said that they didn't see any codes on the diagnotic and it works just fine - no problem.

It's probably a problem with cruise control module , located under the hood in engine compartment . Or a bad connection somewhere . Do you know how to do electrical testing ? Is the air bag light lit on the instrument cluster ?
Could have DTC'S - diagnostic trouble code's stored .
The powertrain control module (PCM) inhibits cruise control operation when certain conditions are not appropriate for cruise control operation. The PCM removes the ground from the cruise control inhibit signal circuit in order to disengage cruise control operation.
Output driver modules (ODMs) are used by the powertrain control module (PCM) in order to turn on many of the current driven devices that are needed to control various engine and transaxle functions. DTC P1558 set indicates that an improper voltage level has been detected on the signal circuit which controls the cruise control inhibit circuit.
Action Taken When the DTC Sets
• The PCM will not illuminate the malfunction indicator lamp (MIL).
• The PCM will store the conditions present when the DTC set as Failure Records data only.
Cruise control is a speed control system that maintains a desired vehicle speed under normal driving conditions. However, steep grades may cause variations in the selected speeds. The electronic cruise control system has the capability to CRUISE, COAST, RESUME SPEED, ACCELERATE, and TAP-UP or TAP-DOWN.
The main parts of the cruise control system are:
• The cruise control module assembly
• The function control switches
• The cruise control release switch
• The clutch pedal position switch (CPP), if equipped
• The stop lamp switch assembly
• The vehicle speed sensor
The cruise control system uses the cruise control module assembly to maintain the desired vehicle cruise speed and operation. The cruise control module assembly has an electronic controller and an electric stepper motor to vary the throttle in each different cruise control mode. The electric controller monitors vehicle speed and operates the electric stepper motor. The stepper motor operates in response to the electronic controller, to maintain the desired cruise speed. The electric stepper motor moves a strap that is attached to the cruise control cable which moves the throttle linkage. The cruise control module assembly contains a low speed limit which will prevent system engagement below a minimum speed of 40 km/h (25 mph). The module assembly is not serviceable.
has this issue been professionally diagnosed? a failure in the module may not be the issue..... pull codes from cruise computer(this may be achieved by jumper wire at diag connecter near passengers strut tower_ cruise light on dash will flash two digit code combinations). is there an ABSlight on also? speed sensor original?
If you know how to set your speed limiter. To set your cruise control, press the stalk in (to the right). The orange light on your dash should go out and you're ready to set your cruise control. You can start the cruise control by either moving the cruise control stalk up or down. Once you start the cruise control you can move the stalk up or down to increase or decrease your cruise speed. You can move it toward you to shut off the cruise control. You can press it in again to go back to the speed limiter. I hope this helps.
as it an automatic and one of the sensor for the cruise control is the VSS then I would be suspecting that there is a problem in the overdrive of the transmission -could be harness connections , TCM
cruises control need these items to operate
brake witch to be operational-- touching the brakes cancels the cruise control
VSS to be operational , --reports the speed of the vehicle so that the cruise controlled speed can be maintained
tachometer to be operational --- will shut the cc of if there is a speed limiter involved
gear position switch to be operational ECM to be operational
if any one item has a break in circuit , the cruise control will turn off
could be as simple as a bad ground connection for the ground wire from the battery
the cruise control is for expressway or throughway driving or any open highway ,it cuts down on fuel by not useing so much gas. it stays at a constant speed it depends where it is set too. after cruise control is set, you can cancel it anytime by turning it off or putting on the brakes. most cruise controls will not set below 40 mph. this is a feature to keep from using it in the city, or populated area. hope this helps you ! good-day !
Go to Auto Zone for a FREE scan of your vehicles computer. It sounds like the vehicle speed sensor control (VSS) for your trans is bad. They will find out exacxtly what the problem is if so. The VSS is linked to your computer for the cruise as well
