Actions
203 - Wingman ACB and ABS have a mismatch
of the Collision Mitigation Confi guration
Possible causes:
• The controller is recognizing that there are components in-
stalled that have part numbers incompatible with the cur-
rent system confi guration. (For example, when a technician
attempts to install a more recent radar sensor onto a ve-
hicle with an earlier Wingman ACB system, or a replace-
ment ECU is programmed incorrectly for this vehicle's sys-
tem.) Contact the dealer or call the Bendix Tech Team at
1-800-AIR-BRAKE for the correct part number to use, or the
reprogramming steps to take for the newer part number to
be accepted.
After addressing the possible causes:
• Clear the Bendix 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.

4.4 CLEARING DIAGNOSTIC
TROUBLE CODES (DTCs)
This procedure must be used when troubleshooting the
diagnostic trouble codes shown in Table 6.
Clear the WingmanACB system Diagnostic Trouble Codes

service tool. Click the
“Clear” button located on the “Read / Clear Fault Codes”
screen. Using ignition power only, power off the vehicle
for at least 15 seconds. Next start the engine and run it at
idle for at least 15 seconds.
Drive the vehicle and, on a test track or suitable section
of roadway, engage the cruise control to verify proper
operation.
If the error returns, call Bendix at 1-800-AIR-BRAKE for
assistance.
4.5 TROUBLESHOOTING DIAGNOSTIC
TROUBLE CODES: POWER SUPPLY
IGNITION VOLTAGE TOO LOW
Measure the ignition voltage under load. Ensure that the
ignition voltage is greater than 10 VDC (volts DC). Check
the vehicle battery and associated components. Inspect
for damaged wiring, damaged or corroded connectors and
loose connections. Check the condition of the fuse.
IGNITION VOLTAGE TOO HIGH
Measure the ignition voltage. Ensure that ignition voltage
is not greater than 16 VDC. Check the vehicle battery
and associated components. Inspect for damaged wiring,
damaged or corroded connectors and loose connections.
POWER SUPPLY TESTS
1. Take all measurements at the radar sensor harness
connector.
2. Place a load (e.g. 1157 stop lamp) across the supply
voltage and ground connection. Measure the voltage
with the load. The supply voltage on pin 8 to ground
should measure between 10 to 16 VDC (volts DC).
3. Check for damaged wiring, damaged or corroded
connectors and loose connections.
4. Check the condition of vehicle battery and associated
components. Ensure the connection to ground is
secure and tight.
5. Using the procedures described by the vehicle
manufacturer, check the alternator output for excessive
noise.
