The air conditioning system can be prone to refrigerant leaks and failure of one or more pressure sensors. The AC pressure sensors should be checked for proper operation when ever the AC system is serviced.

    recharged refrigerant w/ kit and can verify refrigerant is no longer low - now cannot figure out how to reset display "low refrig - a/c off" that I THINK is preventing AC from coming on - anybody?

    No AC due to error message that AC pressure is low.

    seems to have proper level of refrigerant but shuts off saying low refrig I just reset the obii code when it happens, sometimes several times a day and sometimes it will go days without it tripping a low refrig. code!
    go figure....

    DIC indicated that the refrigerate was low so system shut down. Evaporator core replaced ( $1400.00 ) and 4 months later in the winter time the same message came across the DIC.. back in the shop today.
