1. Have the driver run the
Power-Up Self-Test.
Power-Up Self-Test
This is a self-diagnostic check to determine if the system operation is normal.

5.
Park the vehicle. Power off.
Put the key into the ignition and turn to the “ignition power” position.
Toggle the cruise control switch at least once, and leave it in the “on” position.
Start the vehicle, but do not drive away.
Note that if the cruise control is in the “off” position, or if the vehicle is
moving, this test will not run.
The self-test will start after 15 seconds, and takes approximately five (5) seconds
to complete.
(Note that other vehicle system self-tests, e.g. the ABS “chuff” test, may run
during the initial 15 seconds after ignition “on.”)
As the Bendix Wingman Fusion system self-test runs, the driver should hear a
short set of beeps. The test checks the engine, transmission, and brake systems
to make sure they are communicating. In addition, depending on the vehicle,
the test may briefly display a distance alert message and/or cause the Forward
Vehicle Detected icon in the instrument cluster to illuminate; this is normal.
2. Does the driver hear a
long warning beep?
If no problem is found and the test is passed, no additional beeps/lamps will be
displayed nor will a trouble code be set.
If the system has found an issue that will prevent it from functioning properly,
a long
warning beep will sound
to alert the driver, and a Diagnostic Trouble Code (DTC)
will be logged in the system (typically with a status indicator/dash icon illuminated).
For descriptions of all DTCs,
see Section 2.5: Diagnostic Trouble Codes.
3. Have the driver describe
the system behavior that
they believe shows it is not
working properly.
When diagnosing the system, especially in cases where there are no DTCs logged,
find out which part of the system behavior appears to be operating improperly.
4. Fill out the Troubleshooting
Checklist
(pages 7–8)
and create a DTC report
(Appendix F).
The Checklist and DTC Report will clarify the problem and be necessary if a call to
the Bendix Tech Team is needed.
Also See Section 1.2: Narrowing Down the Problem.
