Driver Controls and Instruments Failure to drive safely and use the system properly could result in personal injury and/or death and se- vere property damage. VORAD. However, after 30 days the frozen infor- mation will automatically clear if the vehicle is driven. 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. Maintenance and Diagnostics 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.
In Case of Accident The optional vehicle accident reconstruction capability 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 continuously, but only contains the last 10 minutes (approximately) of system data. The system will cease recording data 30 seconds after the vehicle comes to a stop. 2.
The system tests itself continuously and evaluates the results every 15 seconds. If a problem is de- tected 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. 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 abil- ity to record the system faults during a trip and to notify his maintenance department or Eaton VO- RAD. See "Failure Display Mode/Fault Codes" be- low.
In this mode, specific fault codes are indicated by the pattern of blinks of the driver display unit red FAIL light. NOTE: Once the first memory segment is frozen, the other can’t be frozen. Only by disconnecting the main CPU connector can the second memory segment be preserved. If you desire immediate downloading and interpretation of accident recon- struction data, you must return the CPU to Eaton 3.38
