DESCRIPTION
Some vehicles equipped with Smart Brake Support (SBS) may exhibit a front radar system malfunction
message in the instrument cluster with DTC C1A67:04 (front radar sensor internal malfunction) stored in
memory. This may be caused by water penetrating into the front radar sensor through the breather hole
when exposed to a great amount of water and damaging the radar sensor, resulting in the DTC C1A67:04.
To eliminate this concern, the front radar sensor has been modified.
Customers having this concern should have their vehicle repaired using the following repair procedure.
