Step 11:
In music system if HMI shows all sensors areas screen, it means, sensor are connected properly.
If “critical fault” appears on the screen, Check DTCs again if that particular sensor showing faulty or not. If
Yes, do the re fitment. Else, replace with other another new sensor.
In vehicles with no HMI screen, on activation of reverse gear, if a continuous beep is heard for one second
followed by no beep for one second, then the sensors are connected properly and the system is working
fine. If not, then check DTCs again and do the re-fitment, if necessary.
Note:
1. While assembling, if sensor falls on concrete surface from above 1 meter height, do not use that sensor
for fitment
2. Due to any damage if holder comes out of the bumper, then replace with new bumper.
