STEPS TO TROUBLESHOOTING

Follow these basic steps to quickly and accurately
®
troubleshoot Bendix Wingman
1. Verify the vehicle is equipped with Bendix
Wingman ® ACB. Look for the presence of the radar
sensor on the front of the vehicle. See Figure 1.
2. Understand the driver's complaint. Use the
questions found in UNDERSTAND THE DRIVER'S
COMPLAINT section as a starting point to learn what
makes the driver believe it is not performing correctly.
Be sure to have a thorough understanding of the
system's behavior. This will reduce the troubleshooting
time.
3. Read the Bendix ®
and configuration key indicators via Bendix
ACom ® Diagnostic Software (version 6.3 or later).
If the system generates a trouble code, where a lamp
or icon is illuminated on the instrument cluster, then
® ®
the Bendix ACom Diagnostics Tool should be used to
identify the problem. Bendix
6.3 or later is required for Bendix
addition to reading the trouble codes, document and
review the 4 key system indicators (misalignment
value, stationary object warning indicator, mounting
offset, and confi guration number) as shown in Figure
6. Verify these indicators are within the acceptable
limits according to KEY SYSTEM INDICATORS. See
Table 4.
4. Read the vehicle trouble codes on the instrument
cluster. Use the on-vehicle diagnostics menu to
identify active and inactive engine or vehicle trouble
codes.
5. Use the "Power Up Self Test" to determine if
ACB operation is normal. Determine the version of
Bendix ® Wingman ® ACB that is installed on the vehicle.
See Figure 8 for software version identifi cation. This
feature is available on all Bendix
versions manufactured after 2009.
Key System Indicators (refer to step 3 above)
Mounting Offset This value should equal 0 if the sensor is mounted on the center line of the vehicle. If the service technician
believes the sensor should be mounted offset from center, call 1-800-AIR-BRAKE.
Stationary Object This is a status indicator for the function of stationary object warning. It is available for use in Bendix
