Concern
	The driver receives a warning message in the instrument cluster indicating
that a tail light is not working. (See Figure 1.) However, in some cases, the tail
light actually does work as observed from outside the vehicle.
Technical Background
	The workshop confirms the customer’s observation along with fault codes
880F0E or 880F1E in the rear BCM module. However, the tail light may be
working.
Service Information
Figure 1
New guided fault finding is available in the PIWIS tester as of release 37.000. Consult this repair advice first.
The alternate solution is to replace at least one of the tail lights based on these failure modes:
		A) 
False warning. If the warning message is present and all the tail lights are lighted, the likely causative
part is the outer tail light. Be sure to order replacement parts from the part numbers listed below.		
													
Since 2016, replacement outer tail lights have been available with different part numbers. For the inner
tail lights, old parts were withdrawn and replacement parts are available using the same part numbers.
			Previous Part Number		
Current Part Number

			95863106220			95863106221
			95863106230			95863106231
		B) 
Actual tail light outage. If the warning is present and any of the tail lights are not lighted, replace that tail
light as usual.
