This DTC is not an indicator of a malfunctioning sensor. Do not replace the sensor.
Possible causes:
• Mounting offset incorrect.
Perform the following:
• Check the mounting offset of the radar sensor in ACom ® Configuration screen. The offset value
should not exceed 500 mm.

Possible causes:
• The Wingman system has not found J1939 signal(s) it is expecting from one or more sources. This
could be accompanied by other active DTCs from the same source.
Review the following sections:
• 1.10: Radar Sensor Interchangeability
• 4.7: J1939 Engine Communications Test Procedure
Perform the following:
• Check the expected source(s) of the signal to identify why the signals have invalid data. A
communication link may be disconnected, the power fuse disconnected or blown, or a change was
made to the controller that was incorrect.
• Clear the Bendix ® Wingman ® Advanced ™ system diagnostic trouble codes using the procedure in
Section 4.4: Clearing Diagnostic Trouble Codes (DTCs).

This DTC is not an indicator of a malfunctioning sensor. Do not replace the sensor.
Possible causes:
• The Wingman system has found J1939 signal(s) it is expecting, however the values indicate that
there is a malfunctioning component and/or wiring error.
• Some examples of components, sensors or switches that produce J1939 signals are: brake lamp
pressure switches; steering angle sensors; cruise control switches; gross vehicle weight sensors,
various engine torque signals and wheel speed sensors.
Review the following sections:
• 1.10: Radar Sensor Interchangeability
• 4.7: J1939 Engine Communications Test Procedure
Perform the following:
• Check the engine, engine-retarder, body controller or ABS for trouble codes using the manufacturer’s
diagnostic procedures. The controller that broadcasts the error signal must be investigated first,
however the origin of the signal could potentially be another sensor or switch.
After addressing the possible causes, perform the following:
• Clear the Bendix ® Wingman ® Advanced ™ system DTCs using the procedure in Section 4.4: Clearing
Diagnostic Trouble Codes (DTCs).
