Help with error code 1594 ON SEBRING 2004
 

Hi to all
The story started around 6 months ago when one day while driving on the highway the cruise control went off on its own, and wouldn't turn on unless the car is restarted, this issue continues to happen every now and then until now specially if I use the set button more than 2 or 3 times while the cruise control is on; i.e." if I just use the accelerate and de-accelerate buttons after setting the cruise control the issue doesn't occur", then 3 months ago the check engine lamp came on the dashboard and stayed steady on the dashboard without any noticiable change in the car performance up till now, the last week the battery light on dashboard came on while driving and as I turned the engine off and restarted the car again it went off, I noticed later that it comes on and after some time goes off on its own while driving, measured the voltage of the battery while engine off; was above 12.4 volts and when engine on; it read 14.3 volts, I can't figure out where is the problem; doing the on and off key trick in the starter I got at first 2 codes: P1594 and P1683 then on the second time got P1684, P1594, P1683, P0601; There is no Chrysler dealer around, and I continue using the car daily without any noticiable change in performance, I don't know where is the problem that may be is developing over time and can break down the car later, if anyone had a similar problem or know what's wrong or how to fix these issues I would really appreciate it, thanks.

How old is your car's battery? It may need replacement. If it's good after being properly tested, check for bad grounds.
