The sens or incorporat est he ti re val ve and is s ecured in the wheel by a nut on t he outs i de of the wheel.

Terrain Response System Fault Diag nosis
Terrai n Res pons e relies on the correct funct ionali ty of t he 4 s ub-s ys tems . If one of the s ub-s ys tems develops a fault , theTerrai n Res pons e s ys tem wil l not funct ion, even though the fault i s NOT in t he Terrain Res pons e s ys tem.
T he T errain Response control module and rotary control should only be investigated if there are no apparent faultsin any of the sub-systems. If a fault in a sub-system is subsequently corrected, the T errain Response system willfunction normally after an ignition mode 1 and 2 (on and off) cycle.
Terrain Response Sub-System Faults
W hen a fault occurs i n a s ub-s yst em, t he dri ver i s alert ed by t he il lumi nat ion of a warning indicator and/or an appropri atemes s age for that s ub-s yst em in t he i ns t rument clus ter mes s age cent er. There wi ll be no warning of a Terrain Res ponses ys t em fault .
W hen a sub-sys t em faul t is present and t he dri ver at tempt s t o s el ect a different Terrain Res pons e program us i ng therot ary control or at t he next ignit ion mode 2 (on) cycl e, a mes sage 'SY STEM FAULT SPECIAL PROGRAMS NOT AVAILABLE'wil l appear in the mess age cent er. This impl ies t hat t he Terrain Res pons e s ys tem has a faul t, but only because asub-system fault is preventing its operation. Thi s mes sage will be di spl ayed for 5 s econds per ignit ion mode 2 cycl e, butis repeat ed i f a further s electi on is made by the driver usi ng t he Terrai n Respons e rot ary control or at t he next ignit ionmode 2 (on) cycle.
• NOTE: The mes s age 'SY STEM FAULT SPECIAL PRO GRAMS NOT AVAILABLE' can al so be generated by a fault i n t he Terrai nRespons e rot ary control or control modul e. Refer to the foll owing i nformat ion for det ail s of rot ary control or control modul efaul ts .
It is not possible for the T errain R esponse control module to cause any fault behavior (w arning indicator illuminationor message generation) in any of the 4 sub-systems. Illuminati on of a s ub-s ys t em warning i ndi cat or and/or as ub-s ys t em relat ed mes sage wi ll NEVER be ass ociated wit h a Terrain Res ponse cont rol module or Terrain Res pons es ys t em fault .
The s ub-s ys t em control modul es can det ect a fault wit h the CAN s ignal from t he Terrai n Res pons e control modul e. If afaul t in t he Terrain Res pons e s ys tem is det ect ed, the s ub-s ys tem cont rol modules wi ll operate in t he 'Special programs off's ett ing. The s ub-s ys t em control modul es wil l record a fault code for a fail ure of t he Terrai n Res pons e CAN si gnal . Thes efaul ts can be retrieved us ing IDS and wi ll provide us eful informat ion t o i ndi cat e i nves ti gat ion of t he Terrain Res pons econt rol module or t he CAN net work.
