DESCRIPTION
The back sonar or clearance sonar switch assembly is installed at the base of the driver side of the instrument panel.
When the back sonar or clearance sonar switch assembly is turned on, an on signal is sent to the clearance warning ECU assembly. The intuitive parking assist system operates according to this signal.
