11.14.6.12 Self-test Right Corner Sensor Malfunction

Diagnostic Steps:

Step 1

Carry out the initial inspection.

(a)

Check whether the sensor surface is covered by impurities.

(b)

Check whether the sensor surface is damaged or abnormal.

(c)

Incorrectly spray the rear bumper will cause excessive paint
covering the sensor surface. check whether this situation
exists.
Is the sensor surface normal?

No

Clean the sensor surface, if necessary,
replace the sensor.

Yes

Step 2

Check the wiring harness and connectors.
