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.
