Customer may comment on finding the forward collision/active safety system inoperative, while
receiving no other messages or alerts.
Technicians may find DTC’s B390A 45, B390A 58 and/or DTC B390A 67 set. The cause of the condition
may be a combination of the following:
• The B233 Radar Sensor Module — Short Range performs internal fault detection on
itself, and the module continually runs the program to detect faults.
• If the B233 Radar Sensor Module — Short Range has detected an internal malfunction, it will not
function and the Active Safety System will be inoperative.
• If DTC B390A 58 is set, check for anything that can interfere with the radar signal. Verify
that the area in front of the radar is clean of mud, ice, snow, etc. Also verify the fascia panels
in front of the radar are damage-free, and not obstructed by any add-on accessories such as
emblems, stickers, etc.
• If the vehicle fascia is clean, unobstructed, and damage free, and B390A 58 is still set as
current, the radar sensor has detected a blockage condition and will not been able to clear it
until certain conditions are met.
It will be necessary to drive the vehicle at a speed greater than 9 km/h (6 mph) and allow the
radar sensor to be exposed to other vehicles/traffic in the direction of the radar sensor field of
view. Usually, a short drive in normal traffic conditions will allow the radar sensor to clear the
• The B233 Radar Sensor Module — Short Range cannot be swapped from side to side once they have
been installed on a vehicle. DTC B390A 67 may set if a B233 Radar Sensor Module — Short Range is
reinstalled on the incorrect side of the vehicle.
• If DTC B390A 45 is set, it is most often due to the radar not learning the vehicle position
correctly, rather than an indication of an actual Software programming issue. To correct, run or
re-run the set-up function within the appropriate programming tool. Make sure to perform both the
programming and set-ups steps in SPS.
If further information is needed, refer to DTC B390A – Circuit/System Verification, in SI.
