DIAGNOSIS & TESTING

Problem Symptoms Table

HINT:
Use the table below to help determine the cause of problem symptoms. Check each suspected area in 
sequence. Repair or replace the faulty components, or adjust as necessary.

Self-checking Function

Reversing radar system has malfunction self-checking function, and the function instructions are as follows: 



If reversing radar sensor wire harness and connector are damaged or there is a malfunction in the reversing 
radar sensor body, the instrument cluster will alarm after turning ignition switch ON and shifting the shift lever 
to R.
Specific alarms are as follows:
1. When system is normal, the buzzer does not sound, and reversing radar system enters normal operation 

mode.

2. When there are malfunctions in one or more sensors, relevant reversing radar sensor malfunction will be 

displayed on multi-information display, other sensors can also enter normal operation mode.

ON-VEHICLE SERVICE

Reversing Radar Sensor

Removal

1. Turn off all the electrical equipment and ignition switch.
2. Disconnect the negative battery cable.
3. Remove the rear bumper assembly (

See page 48-30

).

HINT:
The reversing radar sensor connector (arrow) has been 
disconnected when removing the rear bumper assembly.

4. Remove the reversing radar sensor.

a. Press the claws on reversing radar sensor.
b. Remove the reversing radar sensor from the rear 

bumper assembly.

CAUTION

 Be sure to wear necessary safety equipment to prevent accidents when removing the reversing radar 

sensor.

 Operate carefully to avoid damaging the reversing radar sensor when removing the reversing radar
