failure
Check controller to see if
the green LED is
extinguished and the red
LED is lit. If so, perform the
following steps:
1. Remove and reset the
controller circuit board.
If all diagnostics pass, it
is possible that some type
of “one time”
abnormality occurred to
cause the failure.
2. If the diagnostics did not
pass, Replace the
controller circuit board
and verify the failure is
resolved.
3. If the problem is not
corrected, call your local
RTAC representative.
CTRL MAJ None -- •Controller

•Display failure
If the front panel LED
module, LEDs, or switches

steps:
1. Verify that the ribbon
cable from the controller
board to the BMW

abraded, or otherwise
mangled. Replace the
cable if damaged.
2. Reset the controller
board.
3. If the display is still not
operating, replace the
display module.
