Overview of Possible Issues (3.3)

Issue

Description

System familiarity

Verify the system functionality. Is it operating normally or not? Drivers who are unfamiliar
with the system may report they don’t like the way it beeps or how it activates the brakes.
Use Section 3.0: Introduction to Troubleshooting, Section 4.3: Diagnostic Trouble Codes

and

Section 3.1: Questions to Ask the Driver to verify if the system is functioning normally; then
continue.

DTCs caused by
temporary operating

conditions

Some Diagnostic Trouble Codes (DTCs) indicate a temporary condition and will clear when
that condition is no longer present. If these persist, further investigation is warranted. See
Section 3.1: Troubleshooting Basics

.

Radar sensor

misalignment

If the performance of the system seems to be erratic or unpredictable, the radar sensor
could be misaligned and may need to be aligned both vertically and laterally. If there is a
DTC set or if the system does not function, the radar sensor may be severely misaligned
and Wingman Advanced will not operate until this is corrected. See Section 6.01: Vehicle
Applications

.

Inspect the front of the vehicle. If (a) it has been damaged, or (b) if the vehicle does not track
straight, either of these conditions must be repaired before troubleshooting Wingman Advanced.

Radar sensor

blocked

If the system doesn’t seem to work at all, the radar sensor is probably blocked. A DTC will
also be set. Visually inspect it, clear the blockage, turn the ignition on and run through a
power cycle.

Vehicle diagnostic
trouble codes
(DTCs)

The Wingman Advanced system will not operate and will set a DTC if any of the following
vehicle systems also show a DTC: engine, engine cruise, instrument cluster, Bendix

®

ABS,

Bendix

®

ATC, Bendix

®

ESP, or transmission. These components must be repaired and

cleared of DTCs before troubleshooting Wingman Advanced. (NOTE: Clearing the vehicle
DTCs may be the only step needed to reestablish full Wingman Advanced functionality. See
Section 4.4: Clearing Diagnostic Trouble Codes (DTCs)

Damaged radar

sensor or bracket

If the vehicle has been in an accident, it is likely the radar sensor will need to be re-
aligned or replaced. Inspect the radar sensor lens and housing for damage. Radar sensor
discoloration or small scratches may be acceptable. Signifi cant damage will require radar
sensor replacement. Regardless of the exterior condition, check for diagnostic trouble codes
outlined in the Section 4.3: Diagnostic Trouble Codes (DTCs)

to determine if radar sensor

replacement is necessary.

Damaged connector

or wiring

Visually inspect the connector and wire harness for corrosion or chaffi ng. Refer to Section
4.5: Troubleshooting Diagnostic Trouble Codes: Power Supply of this document for additional
troubleshooting.

J1939 network
problems

If the entire system is non-functional, it may be a J1939 network problem. Follow the
instructions in Section 4.6: Serial Data (J1939) Communications Link.

Power to radar
sensor problems

If the entire system is non-functional, another likely cause may be a lack of power to the radar
sensor. Follow the instructions in Section 4.5: Troubleshooting Diagnostic Trouble Codes: Power
Supply.

system performs

normally. Use Table 5 below to learn the causes of potential issues if Wingman Advanced is not performing correctly.
