Produced from 8/2011 through 12/2011
SITUATION
When there is a low tire pressure warning, in some cases the position of the affected tire may be incorrectly
displayed in the instrument cluster and CD (Control Display).
CAUSE
Software error in the RDC (tire pressure control) module in conjunction with wheel electronics part number 4 078
787 or 4 079 152
CORRECTION
Run diagnostics with ISTA/D and work through the corresponding test module. If the test module indicates
replacement of the wheel electronics, identify which part number is installed.
If P/N 4 078 787 or 4 079 152 is
found, replace all four wheel
electronics with P/N 36 10 6 856 227.
If P/N 4 078 787 or 4 079 152 is NOT
found, proceed as instructed by the
ISTA test module and replace the
indicated sensor.
Note: P/N 4 078 787 or 4 079 152 is
easily identified by the stars that
border the face of the wheel
electronics, as seen in the picture to the
left.

Labor operation code 00 00 006 is a Main labor operation. If you are using a Main labor code for another repair,
use the Plus code labor operation 00 00 556 instead.
Even though work time labor operation code 36 11 100 ends in “100,” it is not considered a Main labor operation.
Work time (WT) labor operation 36 11 100 requires an individual punch time.
Even though work time labor operation code 36 99 000 ends in “000,” it is not considered a Main labor operation.
Also, since the “work time” FRU allowance to be claimed is specified, a separate punch time is not required for
work time operation code 36 99 000.
