the vehicle diagnostic system (KDS).
The diagnostic system (KDS) provides the following information.
| (1) |
Self diagnosis : Checking failure and code number (DTC).
|
| (2) |
Current data : Checking the system input/output data state.
|
| (3) |
Actuation test : Checking the system operation condition.

After the replacing of rear corner radar unit or bracket
or wire, perform the radar calibration procedures before
installing the rear bumper assembly. (Failure to calibrate
the radar angle,will cause the malfunction of rear corner
radar system.)
(Refer to Rear Corner Radar Unit - "Adjustment")

|
When replacing rear corner radar unit or rear bumper
with a new one, perform the variant coding procedure by
using the KDS.
|
|
|
To correctly sense vehicles on the neighboring lanes using the radar, the direction
of the sensor and the direction of the vehicle must be aligned.
This is the rear corner radar unit alignment. If this alignment is not performed
as in illustration below, it may cause degradation of detection performance and
false alarms.
In particular, vehicles with damaged rear bumper from accident and vehicles that
replaced rear corner radar unit must carry out this alignment procedure.
| 1. |
Perform the radar calibration procedure using the KDS.
|
| 2. |
Select "BCW(BSD) Radar Calibration" procedure in 'Rear Corner Radar'
system.
|
| 3. |
Perform the "BSD Radar Calibration" procedure as indicated on KDS screen.
