Terrain Response Auto2® And Control Module Faults

If a fault occurs in the Terrain Response® (TR) switchpack, the Interactive Control Display Module (ICDM) turns off and program selection is not possible. The Instrument Cluster (IC) message center displays the message 'Terrain Response Special Programs Not Available' when the fault occurs. The message will be displayed if the fault is present and the driver attempts to select a special program (if the control module is able to do this) or at the next ignition cycle.

If a fault exists and prevents TR system operation, Comfort program only is illuminated. When a fault exists all symbols are greyed out and can not be selected.

If the Instrument Cluster (IC) does not receive a Terrain Response® system message from the Chassis Control Module (CHCM), the message 'Terrain Response Special Programs Not Available' will be displayed when the fault occurs and will be repeated at every time, when the ignition is switched on.
