Abs light is on and cruise control does not engage

cruise controls are governed by 5 settings and sensors
one is engine rpms
vehicle road speed ,( manual transmission will not activate under 20 klms /hr
brake pedal switch
clutch pedal switch ( VSS if auto)
off/on switch control
any one of these not lined up will not allow the cruise control to work

that is normal for cruise, ( its goes dead, when there are other dangerous conditions, or jeep gets lawsuit like TOY did)
did you scan it yet.
??????
that be first. (after checking fuses)
look for ABS failures. or Traction control)

or get car serviced?????? like oper guide stated, for this error?

From what I have read the flashing cruse light is to get you to fix the problem. Any cel will throw the cruse light and cruse will not work. Get your abs checked out and cruse will work again when fixed.

Its the brake system.
The flashing light tells you something is wrong with the cruise components. Could be the brake light switch, or the ABS if equipped.

A vehicle speed sensor provides a signal for the cruise control and also for the ABS braking and the overdrive function. I would start with finding the fuse for the cruise control in your owners manual. Also some cruise controls have vacuum lines attached, if so, check for cracked or broken vacuum lines. Good luck.

make sure the cruise control cable to the throttle isn't too loose, if it is ok, check your brake switch. if it is sending the signal the brake is on it will not allow cruise to work and will do same thing as described about the set light.

When I try to engage the cruise control, the dash light flashes, but it doesn't stay on.

not a volvo mechanic but on most american cars the abs and stc modules are in direct corilation with the cruise even though the cruise is most likely ran from vacume the disengagement is electrical.

most likely the clock spring is not the problem because when u push the button the dash light cruise comes on.wich means that you do not have an open circuit.with a light tester check to see if you are getting power to the cruise control servo.if you are then replace it.if no power you will need a new cruise control stick on the steering column.

Th is is how I fixed mine! Down on the brake pedal there is a small plastic box about 1 1\2 * 1 1\2 in size. It's called the brake stop light, I think. This part disengages the cruise when the brake is pressed. Not sure on it's other uses! Remove the clip from the part where it attatches the the pedal. For more working room you can remove the plastic keeper. The box has three keepers on it. Pry them out gently to remove the top. Two of the copper pieces inside will have contacts on them about the size of a match stick head. Take them out and clean them with an eraser. This solved my problem, I hope it solves yours. Let Me KNOW!
