C
This DTC is not a failure of the FLR-25 radar sensor. Do not replace the FLR-25 radar sensor.
Possible causes:
• These Diagnostic Trouble Codes (DTCs) result from incorrect ignition, battery supply voltage, or
wiring harness issues as measured at the FLR-25 radar sensor.
Review the following sections:
• 2.7: Ignition Voltage Too Low
• 2.7: Ignition Voltage Too High
• 2.7: Power Supply Tests
• 2.12: Troubleshooting Wiring Harnesses
Perform the following:

system DTCs using the procedure in Section 2.6: Clearing
Diagnostic Trouble Codes (DTCs). If the error persists, continue to the next step.
• Verify the ignition supply voltage to the FLR-25 radar sensor is between 9 to 16 VDC.
• Visually check for damaged or corroded connectors.
• Visually check for damaged wiring.
• If the error returns, call the Bendix Tech Team at 1-800-AIR-BRAKE (1-800-247-2725), option 2.
D
This DTC is not a failure of the FLR-25 radar sensor. Do not replace the FLR-25 radar sensor.
Possible causes:
• The system receives an implausible signal (J1939 EBC2 Mean Front Axle) from an external ECU.
Perform the following:
• Clear the Fusion system DTCs using the procedure in Section 2.6: Clearing Diagnostic Trouble
Codes (DTCs). If the error persists, continue to the next step.
• Check the source of the signal to identify why the signal has an error.
• Check the source of the signal for trouble codes using the manufacturer’s diagnostic procedures.
E
This DTC is not a failure of the FLR-25 radar sensor. Do not replace the FLR-25 radar sensor.
Possible cause:
• Vehicles without external yaw rate sensor: the system receives an implausible signal (J1939 EBC2
Mean Front Axle) from an external ECU.
• Vehicles with external yaw rate sensor: the system receives an implausible signal (J1939 VDC2
Yaw rate) from an external ECU.
Perform the following:
• Clear the Fusion system DTCs using the procedure in Section 2.6: Clearing Diagnostic Trouble
Codes (DTCs). If the error persists, continue to the next step.
• Check the source of the signal to identify why the signal has invalid data in the J1939 message.
• Check the ABS for DTCs using the manufacturer’s diagnostic procedures. The ABS is the source of
thesignalandmustbeinvestigatedrst.
• If the error returns, call the Bendix Tech Team at 1-800-AIR-BRAKE (1-800-247-2725), option 2.
F
This DTC is not a failure of the FLR-25 radar sensor. Do not replace the FLR-25 radar sensor.
Possible causes:
• These DTCs may arise from issues such as improper installation or radar blockage.
Perform the following:
• Clear the Fusion system DTCs using the procedure in Section 2.6: Clearing Diagnostic Trouble
Codes (DTCs). If the error persists, continue to the next step.
• Check for proper installation of the FLR-25 radar sensor. This DTC is commonly caused by the
FLR-25 radar sensor being installed backwards.
• Check for FLR-25 radar sensor obstruction. Clean dirt – or packed snow or ice – from the FLR-25
radar sensor if present.
• If the error returns, call the Bendix Tech Team at 1-800-AIR-BRAKE (1-800-247-2725), option 2.
Note: The system will not report newly active J1939 Diagnostic Trouble Codes (DTCs) until the engine has been
running for 15 seconds. Do not attempt to diagnose J1939 DTCs without the engine running.
