1996 on up OBD II systems require a scanner with the 'clear code' feature to reset the SES light.

Otherwise, one can cycle starting and stopping the engine 30 or 40 times to clear the SES light. This is not recommended, though, as it takes a long time.

1999 cadillac deville.. oil light came on and the engine shut its self off


The vehicle has gone into self protection mode. There was no oil pressure (hence the light coming on). Check if the engine oil level is correct, if so, you will have to call your dealer to find the problem. Could be oil pump or maybe just a faulty oil pressure sensor.

Hi! My 1999 Cadillac Deville for about 2 weeks started messaging low refrig-ac-off. Check engine light on!.


When you change your oil is up to you,you set the
months & miles you go. Any car with a reminder
for oil is just a gadget

You were told that your low on a/c refrigerant by the
message

Now the check light related or not has to be addressed,
by checking for codes & diagnosing the effected system

Your a/c system needs repair,not added to, only to leak out
& polute the atmosphere

My 2003 cadillac deville-the service engine soon light came on and stayed


On a lot of cars the light is reset when you get an oil change, air filter etc. It's overdue for a "look see". You can always go to advance auto and borrow the code reader for free. Plug it in under your dash and will read and reset any codes
