Each program is denoted by a s ymbol whi ch repres ent s t he t errai n encountered. The rotary cont rol wi ll only s elect the las tprogram in it s direct ion of rotat ion. Further rot ati on of the control in ei ther direct ion, once the l ast program has beens elect ed, wil l have no effect, for exampl e; once 'Sand' has been s elect ed, furt her rotat ion i n a clockwis e direct ion wil lret ain 'Sand'.
The cont rol module and rot ary cont rol i s connected vi a a harnes s connector which al so cont ains t he wiring for the HDC andDSC s wit ches and the i ll uminati on circuit s . The cont rol module and rotary cont rol uses 4 of t hes e wi res for 12V bat t erys uppl y (i gnit ion - only when the i gni ti on is on) a ground and high s peed CAN bus (pos i ti ve and negat ive).

Road Test
Carry out a road tes t to compare act ual vehicl e braking performance wi th the performance s t andards expected by t hedri ver. The abi li ty of t he t est driver to make val id compari s ons and det ect performance defi cienci es wil l depend onexperience.
The dri ver s hould have a t horough knowl edge of brake s ys t em operat ion and accept ed general performance guideli nes tomake good comparis ons and detect performance concerns .
An experienced brake t echnician will al ways es t abl is h a route that wi ll be us ed for all brake di agnos is road t es t s . Theroads s elected will be reasonably s moot h and level. Gravel or bumpy roads are not sui table because the s urface does notall ow t he ti res t o grip t he road equall y. Crowned roads s houl d be avoided becaus e of t he large amount of wei ght s hifted tot he low set of wheels on t his type of road. Once the route is es tabl is hed and cons ist ent ly us ed, the road s urface vari ablecan be eli minat ed from t he t es t resul ts .
Before a road tes t, obt ain a compl et e des cript ion of t he cus t omer concerns or s uspected condit ion. From t he des cript ion,t he techni cian's experience wi ll all ow t he techni cian t o mat ch pos s ibl e caus es wi th s ympt oms. Certai n components wil l bet agged as pos si ble s us pect s whil e others wil l be eli minated by the evidence. More i mport ant ly, t he cus t omer des cri pt ioncan reveal uns afe condit ions which s hould be checked or correct ed before the road t est . The descri pti on wil l als o help formt he bas i c approach t o t he road tes t by narrowi ng t he concern t o s peci fi c components , vehicle s peed or condit ions .
Begin t he road tes t wit h a general brake performance check. Keepi ng t he des cri pti on of the concern in mind, t est t hebrakes at different vehicle s peeds usi ng both light and heavy pedal pres s ure.
If the concern becomes evident duri ng thi s check, verify it fit s t he descri pti on given before the road t est . If t he concern isnot evi dent , att empt to dupl icate t he condi ti on us ing t he informat ion from the des cri pt ion.
If a concern exi st s , refer t o t he Symptom Chart.
