A self-diagnostic method for an on-board CTIS (10) for sensing system faults and/or vehicle conditions requiring system shut down. There is conducted a variety of self diagnostic tests such as reading the pressure transducer when the main conduit is vented to atmosphere to determine if the transducer is generating impossible output signals, sensing initial tire pressure for a reading so low as to indicate a faulty pressure transducer or a catastrophic failure in the tires, seals and/or conduits, sensing failure of the wet tank switch to close under conditions sufficient to recharge the wet tank which indicates a compressor, tank or switch failure and/or sensing a trend of decreasing tire pressure during an inflation operation which indicates that leakage rates exceed inflation rates. Upon detection of such a system fault or vehicle condition, the CTIS controller, preferably microprocessor based, will signal the vehicle operator of the condition and shutdown (i.e. close wheel end valves and discontinue all further pressure sensing/adjusting operation) the CTIS system. Preferably, the vehicle operator will not be allowed to override the shutdown of the CTIS system.
