Engine Mechanical problem
1998 Honda Accord 4 cyl Two Wheel Drive Automatic 160K miles
This car has a cruise control master on/off switch on the dashboard to the left of the steering wheel and a separate set of controls (RESUME/accel, CANCEL, SET/decel) mounted on the right hand side of the steering wheel. When the cruise control master on/off button is pressed, the light on the button turns on. When the car is being driven above 30 MPH, pressing the SET button does nothing. It should cause the speed to be set and cause an indicator on the dashboard instrument panel to be lit.
I have a Haynes manual for this car, and have tried to isolate the problem with the cruise control. I have located and checked the fuse. The original fuse is good and it is clean. The brake switch appears to work based on the fact that the brake lights work. The control cable between the servo/amplifier and the throttle appears to be adjusted properly. The vehicle speed sensor on the countershaft measures 475 ohms, and the Haynes manual indicates that it should be between 400 and 600 ohms, so that appears to be good. I was unable to access the vehicle speed sensor on the mainshaft as it is located underneath the battery, and disconnecting the battery will lead to other problems (radio anti-theft device). I could pursue that, but the fact that the speedometer works suggest that this sensor is also working. The Haynes manual did not have any other suggestions.
A Honda dealer wanted $100 just to connect their computer to the onboard diagnostics. I declined that for now, but did buy an Actron CP9180 AutoScanner. I am still learning that tool (and OBDII), but did get it to tell me that all the diagnostics passed, and there were no codes to be checked out.
Are there any known failure modes or diagnostics that can be tried? Any suggestions on how to get the cruise control to work will be appreciated!
