(SA 42, SPN 158, FMI 3, 4)
FLR Supply Voltage Out of Range
Overview
This code indicates that the Forward Looking Radar (FLR) has determined that the supply voltage is, or was, out of range.
Diagnostic Trouble Code (DTC) Detection
At power up and during operation, the FLR monitors supply voltage. If the supply voltage fails outside the normal operating range (+9 to 16
Vdc) the Diagnostic Trouble Code (DTC) will set and the FLR will power down to prevent damage. In some cases the FLR may power down
before the Diagnostic Trouble Code (DTC) is set. This Diagnostic Trouble Code (DTC) may also trigger Driver Interface Diagnostic Trouble
Codes (DTCs) 32 and 35 for loss of J1939 messages. In this case correcting this condition should clear the other Diagnostic Trouble Codes
(DTCs).
