NOTE: These vehicles are orginally built with the center display GML8-611J0* and are not applicable to this TSB. Only if
the center display has been replaced with GRT7-61-1J0 or GRT7-61-1J0A in the past is the vehicle applicable to this
TSB.
DESCRIPTION
Some vehicles may exhibit a malfunction where the touch screen operates by itself (ghost touch). An example ghost
touch would be the map on the center display scrolls without touching it. This is caused by heat expansion and
contraction of the center display deforming and loosening the touch panel, resulting in an increased wire resistance (As a
result, DTC B108E:04 may be stored). To eliminate this concern, a protection film has been added in the touch panel to
prevent deformation.
Customers having this concern should have their vehicle repaired using the following repair procedure.
NOTE: This TSB repair can fix ghost touch, surface peeling issues, and spider cracks (may clear DTC B108E:04).
• Ghost Touch
• DTC B108E:04 may be stored
(Touch screen operates by itself)
• Surface Peeling
• DTC B108E:04 may be stored
• Spider Cracks
