Question about 2007 Dodge Ram 1500 Quad Cab Sport
I'm hoping someone here could answer a question for me.
I noticed that whenever I pressed the DECELERATE button on the steering control, it actually shuts off the cruise control completely. It happend to me twice yesterday when I used the decelerate button to slow down for a slower vehicle in front of me going up a hill. When I pressed RESUME & nothing happened that I realized the the "cruise" light on the dashboard was off.
Then a little while later, I actually saw the cruise light turn off when I was holding down the DECELERATE button the second time. I thought at first that maybe because the CANCEL button was located between the RESUME/ACCELERATE and DECELERATE control. But after pondering about it, I figure it should not shut off the cruise control completely since the ON/OFF button is on the other end of the steering wheel.
If anyone has any ideas what's causing this little inconvenience would be much appreciated.
My vehicle is a 2007 Dodge Ram 1500 SLT.

SOURCE: Cruise control shuts off up hill
if the cruise control light has come on then i would take it to a dealer and have them hook it up to the scan tool and see what exactly is going on. I think that pretty much is going to be your BEST bet. However you should check your brake fluid because if your brake fluid is too low then the cruice control will not work.

After the light goes out does it come back on while driving down the road?
If it does this sounds as if you may have a heat sensitive problem at the cruise motor. this has a sensoe that turns the light on when it is engaged. when you turn it off and sits a while does the heat under the hood goes higher expanding the circuts an open circut. You may have to replace the board in the motor.

Look under the hood to check and make sure there is two steel wire cables connected to the throttle body. i had the same problem on my 02 dodge ram, turns out that just one of the cables came loose

Tips for a great answer:
The On/Off switch
The Resume/Accel switch
The Set/Coast switch
The TCC brake switch
The stop lamp switch
The throttle actuator control (TAC) motor
The vehicle speed sensor
Cruise Control Engaged
The cruise control system will engage and adjust the vehicle speed based on the activation of the following cruise control switches:
The cruise control switches are located on the multifunction/turn signal lever.
The powertrain control module (PCM) monitors the signal circuits of the cruise control switches in order to determine when to capture and maintain the selected vehicle speed. The PCM uses the throttle actuator control (TAC) module motor in order to control the vehicle speed. For further information on the TAC System, refer to Throttle Actuator Control (TAC) System Description in Engine Controls - 4.2 L.
Ignition positive voltage is supplied from the 10 ampere HVAC 1 fuse to the cruise control switch via the ignition 3 voltage circuit. When the normally open cruise control On/Off switch is turned On, the switch closes and the PCM detects a high signal voltage on the cruise control on switch signal circuit. When the normally open Set/Coast switch is pressed, the switch closes and the PCM detects a high signal voltage on the cruise control set/coast switch signal circuit. To engage the cruise control system, turn the On/Off switch On and momentarily press the Set/Coast switch. The PCM will confirm that the cruise control enable criteria has been achieved. The PCM will engage the cruise control system and record the selected vehicle speed. The PCM sends a class 2 message to the instrument panel cluster in order to illuminate the cruise control indicator. Pressing the accelerator pedal, while the cruise control system is engaged, will allow the driver to override the cruise control system in order to accelerate the vehicle beyond the current set vehicle speed. When the accelerator pedal is released, the vehicle will decelerate and resume the current set vehicle speed. The driver can also override the current set vehicle speed via the Set/Coast switch and the Resume/Accel switch. When the cruise control system is engaged, pressing and holding the Set/Coast switch will allow the vehicle to decelerate from the current set vehicle speed without deactivating the cruise control system. When the Set/Coast switch is released, the PCM will record the vehicle speed and maintain the vehicle speed as the new set vehicle speed. When the cruise control system is engaged, momentarily pressing the Set/Coast switch will allow the vehicle to decelerate at 1.6 km/h (1 mph) increments for each time that the Set/Coast is momentarily pressed, with a minimum vehicle speed of 37 km/h (23 mph). When the normally open Resume/Accel switch is activated, the switch closes and the PCM detects a high signal voltage on the cruise control resume/accel switch signal circuit. Activating and holding the Resume/Accel switch, when the cruise control system is engaged, will allow the vehicle to accelerate to a greater vehicle speed than the current set vehicle speed. When the Resume/Accel switch is released, the PCM will record the vehicle speed and maintain the vehicle speed as the new set vehicle speed. When the cruise control system is engaged, momentarily activating the Resume/Accel switch will allow the vehicle to accelerate at 1.6 km/h (1 mph) increments for each time that the Resume/Accel switch is momentarily activated, with the maximum acceleration total of 16 km/h (10 mph) over the current set vehicle speed . Momentarily activating the Resume/Accel switch, after the cruise control system has been disengaged by pressing the brake pedal, will recall the previous set vehicle speed that is recorded in the PCM.
