Instruments and Controls Identification The side sensor only detects objects within its field of view, next to the tractor. A vehicle far- ther back, behind the field of view, will not be detected. days the frozen information will automatically clear if the vehicle is driven. Maintenance and Diagnostics The side sensor range is set to detect average sized vehicles, 2 to 10 feet (0.5 to 3 meters) away, in the adjacent lane. The side sensor provides a 15 degree vertical by 15 degree horizontal beam pattern. 1. Keep the antenna assembly and side sensor(s) free of a buildup of mud, dirt, ice, or other debris that might reduce the system’s range.
The radar beam of the CWS will detect near range cut-ins of approximately 30 feet (9 meters) or less, depending on the angle of en- trance into the lane in front of your vehicle. 2. The system tests itself continuously and evalu- ates the results every 15 seconds. If a problem is detected with the front radar system, the red FAIL light on the DDU illuminates continuously as long as the failure is active. The corresponding fault code is stored in the CPU’s memory. WARNING 3. Both active and inactive fault codes can be indi- cated by the DDU when the system is placed in failure display mode. Inactive faults are those that have occurred and have cleared. Active faults are still present.
Fault codes provide the driver the ability to record the system faults dur- ing a trip and to notify his maintenance depart- ment or Eaton VORAD. See "Failure Display Mode/Fault Codes" below. In this mode, specific fault codes are indicated by the pattern of blinks of the driver display unit red FAIL light. Heavy rain or water spray at the side sensor may temporarily prevent the system from providing adequate warnings. Failure to drive safely and use the system prop- erly could result in personal injury and/or death and severe property damage. NOTE:
A continuous fixed object on the right side of the vehicle such as a guard rail, wall, tunnel, or bridge may cause the side sensor alert light to stay on. 4. Each fault code is a two-digit number, as shown in Table 2.1 . The red FAIL light blinks the same number of times as the first digit, a pause of ap- proximately 3/4 of a second follows, then the light blinks the same number of times as the sec- ond digit. In Case of Accident The optional vehicle accident reconstruction capabil- ity provides two segments of system data, one of which can be stored in system memory. Push and hold the DDU range knob for at least 5 seconds to store the first segment.
Within 6 seconds, the green SC indicator light will blink rapidly 8 times, confirming that the data has been saved. If the range knob is pushed again, a fail tone will sound. After the first segment is saved, the second segment runs continu- ously, but only contains the last 10 minutes (approxi- mately) of system data. The system will cease re- cording data 30 seconds after the vehicle comes to a stop. 5. Additional fault codes are blinked out at intervals of approximately 3 seconds. After all of the fault codes have been blinked out, a code 41 will be blinked out. Failure Display Mode/Fault Codes NOTE:
If the vehicle does not have ON/OFF control on the DDU, press and hold the volume knob after the ignition key is turned on and the 15-second self-test is complete. 1. Press and hold the DDU volume control and power ON/OFF knob for at least 9 seconds. The system will turn off if you release the knob before 9 seconds. After 9 seconds, the DDU FAIL light begins to blink out the fault codes. After a 3-second interval additional fault codes, if present, will be blinked out. A code 41 will be NOTE: Once the first memory segment is fro- zen, the other can’t be frozen. Only by discon- necting the main CPU connector can the sec- ond memory segment be preserved.
If you desire immediate downloading and interpretation of accident reconstruction data, you must return the CPU to Eaton VORAD. However, after 30 2.24
