• in general one should get the computer read and checked, although often they are just temporary glitches
• one can often reset the error messages by disconnecting battery (black terminal) for 10 minutes although the messages may recur if there is an ongoing issue.

• when all of these suddenly light up and stay on and the Cruise control no longer works but just blinks then:
  • most likely problem is the petrol cap is loose or not replaced correctly!
  • there may be other causes such as:
    • worn seal around petrol cap
    • may be an issue after a flat battery - hmmm…not sure on this
    • the inhibitor safety switch broken
    • check the error code:
      • Po456 indicates an evaporative leak in the system such as a loose or worn petrol cap, and if not these may need smoke testing to find the leak such as in a cracked hose

• this is a real pain and only likely to occur on cars with lots of travel especially on dusty roads
• see my blog on how to replace one with a second hand one (as long as air bags did not go off in an accident)
