Are all tests normal?

3

Inspect the power and grounding circuit of the parking radar control module.

(a) Refer to 11.12.6.10 System can't self-inspect (buzz doesn't make a sound)

Confirm whether the circuit is normal.

4

Replace left side sensor

(a) Replace left side sensor. Refer to11.12.7.2 parking motor sensor replacement.

5

Inspect the parking radar self-inspection function to confirm the fault has been
removed.

Next

No

Repair or replace the harness.

11.13.6.18 Right front sensor fault

Diagnostic steps:

Notes:

Inhibit starting the vehicle when performing this inspection step; otherwise, the damage to the
vehicle and personal injury may be caused.

1

Perform the following initial inspection.

A. Check that the sensor surface must not be covered by foreign matters.

B. Check that the sensor surface is free from breakage.

C. Incorrectly painting the rear bumper will cause excessive paint coating to be accumulated on

the sensor surface. Check whether this abnormality exists.

Is the sensor surface checked OK?

2

Check harness and connector.

(a) Rotated ignition switch to "OFF"

position.

(b) Disconnect parking motor control

module harness connector SO32.

(c) Disconnect parking motor right

side sensor CA30.

(d) Measure the connection situation

of each terminal in the following
table.
