    The Town Car suspension has an onboard computer which records codes, much like an engine computer. By retrieving the code(s) in memory you can learn which part of the system is causing the light to come on.


    The pump does not normally cycle on and off. It may run a few seconds, but then should shut off. Excess cycling normally indicates a leak in the system or a bad pump.
