Possible Problem(s) Possible Solution(s)
Major None -- •Controller 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 technical support.
Major None -- •Controller failure
•Display failure If the front panel LED module,
LEDs, or switches fail, perform
the following steps:
1. Verify that the ribbon cable
from the controller board to the
BMW display is not cut,
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.
