2007 Ford five hundred cruise control turns off when you hit a bump


First off the cruise control is computer controlled , need to check for diagnostic trouble code's . Your vehicle has electronic throttle control also . If your don't have a factory or professional grade scan tool your odds of being able to fix this yourself is close to zero ! You could find a wiring diagram an do some voltage drop testing ,mite find lose connection .
Speed Control
The speed control system consists of the following components:
  • Speed control switches
  • Speed control deactivator switch
  • Speed control indicator
  • Powertrain control module (PCM)
  • Electronically controlled throttle body
  • Clockspring
The speed control system is controlled by the PCM. The speed control system is designed to maintain a selected vehicle speed between 48 and 200 km/h (30 and 124 mph). The speed control system is controlled by the steering wheel mounted switches (ON, OFF, SET+, SET-, CANCEL, and RESUME), and the brake pedal. The steering wheel mounted switches are hardwired to the PCM.
The speed control functions include:
  • Turning the speed control system on.
  • Setting and maintaining the desired vehicle speed.
  • Accelerating the vehicle speed.
  • Decelerating the vehicle speed.
  • Resuming the prior vehicle speed.
  • Turning the vehicle speed control system off.
  • Canceling the speed control.
The clockspring provides the electrical interface between the steering column wiring and the speed control switches in the steering wheel.
The inputs to the PCM are:
  • Output shaft speed (OSS) sensor
  • Speed control switches
  • Stoplamp switch
  • Speed control deactivator switch
  • SJB messages
The outputs of the PCM for the speed control system are:
  • Speed control indicator lamp
  • Throttle command
The throttle position is completely controlled by the PCM through the electronically controlled throttle body. Speed control electronics are contained entirely within the PCM.
When the speed control system is active, the PCM corrects for deviations in the actual vehicle speed by proportionally moving the throttle plate. The PCM modulates the throttle to minimize error between actual vehicle speed and the desired speed.
The PCM strategy uses the throttle control for smooth accelerations.
The PCM sends a serial message over the controller area network (CAN) to the instrument cluster whenever the speed control telltale should be turned on or off.
In the event of an OFF command or a deactivation request from the deactivator switch, the speed control system carries out a hard deactivation and immediately returns the throttle to the idle position.
In the event of a CANCEL command input, the system deactivates and the throttle returns to the idle position at a smooth and controlled rate.
The speed control system provides self-diagnostics. The speed control system is disabled anytime an error is detected in the system. No cluster telltale or message center messages are displayed when faults occur. Fault codes are logged by the PCM.
An electronic throttle control (ETC) system fault also causes the speed control system to be disabled. In this case, an ETC system warning indicator or message center message is displayed.
Additionally, the following conditions cause the speed control system to deactivate:
  • Transmission gear selector is put into a position other than D or OD.
  • Parking brake is applied.
  • Speed control set speed is over-ridden with the accelerator pedal for a period longer than 5 minutes.
  • Vehicle speed loss from set speed of greater than 16 km/h (10 mph) occurs.
  • Vehicle speed falls below the minimum allowable limit of 48 km/h (30 mph).
  • Speed control switch is pressed or stuck longer than 2 minutes.
  • Powertrain Control Module (PCM) Diagnostic Trouble Code (DTC) Index DTC Description Action P0579 Cruise Control Multifunction Input A Circuit Range/Performance Go To Pinpoint Test C . P0581 Cruise Control Multifunction Circuit High Go To Pinpoint Test C . P0720 Output Speed Sensor Circuit REFER to the Powertrain Control/Emissions Diagnosis (PC/ED) manual. P0721 Output Speed Sensor Circuit Range/Performance REFER to the Powertrain Control/Emissions Diagnosis (PC/ED) manual. P1500 Vehicle Speed Error REFER to Section 307-01A or Section 307-01B . P1501 Vehicle Speed Error REFER to Section 307-01A or Section 307-01B . P1703 Brake On/Off Failure Go To Pinpoint Test B .

Where is the fuse for cruise control on a 2003 envoy


It is HVAC 1fuse #39 in the rear fuse block ,this powers the on/off switch for cruise control ! Fuse Block - Rear Beneath the left rear seat. What engine does it have ? 4.2 L or 5.3 l There is no vacuum involved in the operation of the cruise control ! Your vehicle has electronic throttle control .
Cruise control is a speed control system that maintains a desired vehicle speed under normal driving conditions at vehicle speeds above 40 km/h (25 mph). Steep grades may cause variations in the selected vehicle speeds.
The following are the main components of the Cruise Control System:
?€¢
The powertrain control module (PCM)


?€¢
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:
?€¢
On/Off


?€¢
Resume/Accel.


?€¢
Set/Coast

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.

Transmission speed sensor


You could have a faulty speedometer/odometer combination meter causing a false Vehicle Speed Sensor error.
My 1998 Sienna had the following symptoms:
- Speedometer and odometer failed intermittently
- The check engine light would come on and I would get a p0500 code in the OBDII.
- The cruise control would stop working at the same time the speedometer failed.
There is a speed sensor in each one of the tires and they feed the speed information to the ABS ECU. From the ABS ECU the speed signal goes to the speedometer/odometer combination meter, and from there it goes to the Engine Control Module and to the Cruise Control ECU. I could see a signal coming into the speedometer/odometer, but no signal going out. Replacing the speedometer/odometer combination meter fixed the problem.

2007 chrysler 300c cruise control wont lock in and hold speed says i ts on the dash but is not engauging


.
Hello, "arthur o'neill".
Your car has parts under the hood to engage and control the throttle.
Those parts, as well as others, such as the speedometer,
and its cable must all be working properly,
for cruise control to work.
Either take it a mechanic, or get a 'shop manual',
for your particular model.

I would change the transmission filter.if clogged it will slip and loose power on steep upgrades try that it is inexpensive. If that don't help you may need a new transmission.

My cruise control can be set only at a speed higher than 20 mph. I want to set it even at a speed of 10 mph. How to do this?


Your cruise is not desinged to work at those low speeds. The cruise module needs vacum that your engine cannot produce at those low rpm's. Most will not work under 35-45 mph.
