Condition
Customers may comment that when in reverse the radio screen is black with a red
triangle and a red camera with a circle and slash through it.
Cause
Poor terminal connection on the Reverse Camera Coax cable.
We are working on new coax cables but currently do not have new cables to correct
the condition for the Acadia and XT6. New parts should be available from CCA in
January.
Correction:
If you encounter a vehicle with a Black screen in Reverse, and a B395A, 3A, 08, 72 DTC(s) in the CSM (radio), please
do the following.
Access the coax cable from the inline connection to the CSM, located behind the right kick panel. Cycle the inline
connection, then verify that the camera is working properly. If it starts working for XT5 replace the cable. New
cables are available through the WPC, see chart below.
For Acadia and XT6 wrap the inline connection diagonally with electrical tape to stabilize it and verify the system
is still functioning properly.
This should repair the condition, but it will still need the new cable when it is available. New parts should
be available from CCA in January.
If the B395A is in the Video Processing Control Module,
Look at all of the cable connections between the VPM and the backup camera or the camera itself as the
issue. Most likely it is a connection concern. To test them, cycle the connectors, and if it comes back online,
for XT5 replace the cable. New cables are available through the WPC, see chart below.
For Acadia and XT6 wrap the inline connection diagonally with electrical tape to stabilize it and verify the system
is still functioning properly.
This should repair the condition, but it will still need the new cable when it is available. New parts should
be available from CCA in January.
