disconnect delta if the target position has been reached 264 then the system stores the present position value in memory 265 and then proceeds to idle mode 40 otherwise 266 the system determines if the present position is too low if the present position is too low 268 then it proceeds to detect whether or not the legs are at maximum extension otherwise 270 it moves on to determine whether or not the present rv position is too high if the support legs have reached maximum extension 272 then the system proceeds to error mode 42 if the leg extension is not at maximum 274 then the system extends the legs further 276 which raises the angular position i e the front of the rv if the present position is too high 278 then the system determines whether or not the rv legs have reached a minimum retraction distance if the legs are at minimum retraction 280 then the system proceeds to error mode 42 if not 282 then the system retracts the legs further 284 which lowers the angular position i e the front of the rv after the system completes steps 276 286 and 284 it will loop back to the beginning and will repeat the procedure until the rv has reached the desired position as depicted in fig h once connect mode 176 has been activated pressing any button 290 immediately cancels the mode 176 causing.
