11.13.6.16 Intermediate 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) Inspect and ensure that the surface of sensor can't be covered by foreign matters.

(b) Inspect and make sure that the sensor surface has no damage or other situations.

(c) For painting process of rear bumper which may cause large deposit of sensor, inspect

whether there is any abnormal condition.

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 SO51.

(d) Measure the connection situation

of each terminal in the following
table.
