Diagnostic Trouble Code (DTC)

Component Code: 92
(SA 42, SPN 886, FMI 14)
Forward Looking Radar Not Detecting Objects or Radar Blocked
Overview
This code indicates that the Forward Looking Radar (FLR) has not detected a target in an excessive amount of time or has become
blocked.
Diagnostic Trouble Code (DTC) Detection
When the FLR has gone a period of time without receiving any reflected radar signals this Diagnostic Trouble Code (DTC) is set. This
may simply indicate that the vehicle has been in an extremely desolate area without any vehicles or objects to reflect its radar signals.
Non-vehicular objects such as road signs, highway overpasses and background trees should provide enough radar signals to prevent this
Diagnostic Trouble Code (DTC) from being set. This Diagnostic Trouble Code (DTC) may also indicate that the FLR has become blocked by
mud, snow, ice, or other debris.

message indicating the Diagnostic Trouble Code (DTC) condition. If the VS-400 system once again begins to detect objects, the condition
will clear and the system will resume normal operation.
