Install an HC2 sensor shield, if not previously installed (see Warranty history).
PROCEDURE
For conditions that are similar to the situation described:
1. Run diagnosis with ISTA and work through corresponding test module for related fault codes in the
SWW system.
Did ISTA identify root cause?
YES – follow diagnostic recommendations.
NO – Obtain sensor shield (detailed in parts list below), then continue to step 2.

This sensor shield prevents the incorrect scattering of the radar
signals at the rear bumper, which causes false warnings.
