162 - DTC showing a problem in the interface of
the Wingman ACB brake system.
Find and correct all other Diagnostic
Trouble Codes (DTCs) using Acom before
attempting to diagnose this trouble code.
From the starter screen select EC-60
and “Start with ECU”. When prompted to
choose the hardware interface, confi rm that
the Bendix® EC-60™ controller protocol
used will be J1708. Verify that the vehicle
is built with a Bendix ABS Advanced with
ESP® (Electronic Stability Program) brake
system.
Click “DTC” to show the diagnostic trouble
codes.
An in-depth investigation of the ABS
system is required to narrow down
the exact cause of a DTC 162. The
investigation requires information from both
Active ABS Diagnostic Trouble Codes and
ABS Information Events stored in the ECU
memory.
To obtain a report of all the information
stored in the ABS controller, select
the Report button. If further diagnosis
assistance is required from the Bendix
Tech Team at 1-800-AIR-BRAKE, save this
report (in HTML format) to e-mail to them.
Notes about interpreting ABS Info Events:
The ABS Info events are a history of
signifi cant events in the life of the ABS
control system and are not cleared.
Rather the log keeps track of number of
occurrences, time stamp, power up time of
the event, and the speed of the vehicle. In
using the ABS Info Events care must be
taken to apply the time of a logged event
to the current time which an issue is being
diagnosed.
Possible causes:
• The controller may be recognizing that there are components
installed that have part numbers incompatible with the current
system confi guration. (For example, when a technician
attempts to install a more recent radar sensor onto a vehicle
with an earlier Wingman ACB system.) Contact the dealer
or call the Bendix Tech Team at 1-800-AIR-BRAKE for the
correct part number to use, or the re-programming steps to
take for the newer part number to be accepted.
• The controller may be recognizing that there are components
installed that have part numbers incompatible with the
current system confi guration.
• The controller may be detecting an intermittent power supply
to the radar sensor using. See the procedures in Section
4.5, making careful inspection of the wire circuits that supply
power and ground to the sensor.
• The controller may be detecting an active DTC for INVALID
OR INCORRECT J1939 XBR DATA. This will occur only
on a new vehicle that was assembled with an incorrectly
programmed ABS ECU or an older vehicle that had the ABS
ECU replaced with one that was incorrectly programmed.
This DTC indicates the parameters are not set properly to
activate Wingman braking. Replace ABS ECU with one
properly confi gured for Wingman.
• The controller may be detecting an ABS Information Event
for Axle 1 ABS Mods, or Axle 2 ABS Mods, or Trailer (ESP)
Mod, or ATC Mod. This means that the Wingman system
is recognizing that the ABS pressure modulator valves,
ATR relay valves, or the front or rear axle or trailer have
exceeded their service life. There is no loss of ABS braking,
traction control, or stability functions during this condition,
however the Wingman adaptive cruise control and collision
mitigation features will not be available. All of the pressure
modulators and ATR relay valves should be replaced. After
replacement, call the Bendix Tech Team at 1-800-AIR-
BRAKE who will supply a method to reset the counters and
clear the DTC.
After addressing the possible causes:
• Clear the Bendix ® Wingman ® ACB system DTCs using the
procedure in Section 4.4: Clearing Diagnostic Trouble Codes
(DTCs)
.
• If the error returns, call the Bendix Tech Team for assistance
at 1-800-AIR-BRAKE.
164 - Wingman ACB braking overuse
Possible causes:
The system was used improperly, such as on grades.
Review the following sections:
Section 1.08: Alerts and
Warnings (Brake Overuse Alert description), also Appendix B7.0
Perform the following:
• Check engine, and engine retarder trouble codes.
• Clear the Wingman ACB trouble codes using the procedure in
Section 4.4: Clearing Diagnostic Trouble Codes (DTCs).
• If the error returns, call the Bendix Tech Team for assistance
at 1-800-AIR-BRAKE.
