TCS Inhibited Operation

There are a number of reasons that the TCS will be disabled:
^ TCS switch is in the OFF position.
^ EBTCM senses a valid brake switch input.
^ Park brake is engaged.
^ Catalytic converter temperature rises above the normal operating range.
^ TCS thermal shut-down mode is in effect.
^ PCM sets a DTC that turns on the CHECK ENGINE indicator.
^ EBTCM sets a wheel speed sensor DTC, a TCS system DTC, C1275, U1016, U1255, U1300, or U1301.
