        Detach the claw of the retainer of the urea tube with heater connector, pull up the retainer and disconnect the urea tube with heater connector from the urea pump.

        Note


        • If there is any solidified urea solution (white solids) on the connection area, clean the solids off with a damp cloth, etc., before disconnecting the connector.

        • Be sure to disconnect the urea tube with heater connector by hand.

        • Check for foreign matter in the urea pump and around the urea tube with heater connector. Clean if necessary. Foreign matter may damage the O-ring or cause leaks in the seal between the urea pump and urea tube with heater connector.
