Do you know what all is involved in C.C. operation ?


Cruise control is a speed control system that maintains a desired vehicle speed under normal driving conditions at speeds above 40km/h (25 mph). However, steep grades may cause variations in the selected speeds. The main components of the cruise control system are:
• The cruise control module assembly
• The cruise control switches
• The cruise control release switch
• The powertrain control module (PCM)
• The stoplamp switch assembly
• The vehicle speed sensor


The cruise control module controls the operation of the cruise control system. The cruise control module monitors the signal circuits of the cruise control switches. When the normally open cruise On/Off switch closes with a switch activation, the cruise control modules detects a high voltage on the signal circuit. The cruise control module activates the cruise control system.The set/coast switch and the resume/accel switch will not operate the system when the cruise control module has not activated the system based on the cruise control on/off switch signal circuit .
The cruise control module monitors the cruise control set/coast switch in order to determine when to capture and maintain the vehicle speed. The cruise control module monitors the vehicle speed signal circuit in order to determine the desired speed. The PCM pulses the vehicle speed signal circuit at 4000 pulses per minute. After an initial set speed has been established, the cruise control module also uses the cruise control set/coast switch signal circuit in order to tap down the set speed when the cruise control module detects a switch activation.
The cruise control module monitors the cruise control resume/accel switch signal circuit in order to determine when to resume the previous set speed. This feature only works within the same ignition cycle and as long as the cruise wasn't turned off using the cruise control On/Off switch since the last cruise engagement. After the set speed has been resumed, the cruise control module also uses the cruise control resume/accel switch signal circuit in order to tap up the set speed when the cruise control module detects a switch activation.
The cruise control module assembly has a controller and an electric stepper motor to vary the throttle in each different cruise control mode. Two components in the module assembly help to do this. The electronic controller and the electric stepper motor. The controller monitors vehicle speed and operates the stepper motor. The stepper motor operates in response to the 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

problems with cruise control include , clutch switch, brake switch , low road speed , control module , speedo sender unit
make sure that all those items are adjusted as one one will stop the cruise control from engaging

The main cause for this problem is failure to maintain a set speed. Check the cruise control fuse. If the cruise control system fails to maintain the set speed, check the throttle linkage adjustment. Use your manual for this. Honda Accords parts would help you to buy other Honda Accord parts in good price.

What are telling,for me is the diafrag of the servo of the cruise control,this one is located under the hood.

The cruise control switches are located on the steering wheel. When the cruise control is turned on there will be a green light luminated on the dash that says "cruise". When at the desired speed press "set" to set the cruise control at that speed.

Here are the steps in using cruise control:

1. Get on a road you will be traveling at the same speed for a long period of time, such as a freeway.
   
2. Reach your desired speed. Choose a speed that allows you to move with the flow of traffic and not go over or under the designated speed limit for that road.
   
3. Locate the ON and SET buttons on your steering wheel. Press ON first and SET after. Your cruise control is now activated. Most vehicles must be traveling at least 30 miles per hour to set the cruise control.
   
4. Press and hold the SET button if you wish to use cruise control at a higher speed. Hold until your desired speed is reached.
   
5. Decrease speed by pressing the COAST button.
   
6. Push the brake pedal to disengage the cruise control function. If you wish to return to the previous set speed, use the RES (resume) button. You must be traveling at least 30 miles per hour for this function to resume.
   
7. Erase any previous speed by pressing the OFF button.
   

Does it hang out at 18-20MPH, regardless of your speed?
Mine did the same thing. The problem was an open circuit inside the gauge itself, and there's no repair for the parts. You'll need to get a replacement speedometer gauge, or simply buy a replacement instrument cluster.


If it's not doing the "20mph" thing, then it's possible that you just need a new engine speed sensor. This is located on the rear of the engine block, and is hard but not impossible to reach and replace.

One way to test is to set the car on cruise control when the speedometer is working. If the speedometer cuts out ,but the cruise is still able to maintain your speed, then the sensor is OK and the problem is the gauge. If the cruise control also cuts out, then the sensor is bad.

there are 2 possible parts here, one is a transmission speed sensor, this part tells the cruise what speed u set and keep it there, the other is the the actual actuator that holds the throttle at the right position to maintain set speed, other less common issue's make sure the brake and clutch (if manual trans only) cruise cut off switche's are ok

Sounds like possibly a safety switch associated with the brake or shifter is engaging intermittently. There is definitely one behind the brake because when you apply the brake the cruise kicks out. Try looking for this switch and check it out.

cruise control on your escape will work at 30 mph and up. Press 'on 'button, then press gas pedal 'til u reach desired speed, press 'set acc' and you'll be cruisen. You can also do it this way, press 'on' button, then press and hold 'set/acc' button, car will accelerate, let go of button when u reach desired speed. Putting on brakes will deactivate cruise, u can then press 'RSM' to resume speed.
