Troubleshooting parking sensors
When replacing a bumper, problems often arise with the operation of the parking sensors, which may begin to make errors or turn off completely. This is due to incorrect connection of the connectors or damage to the wiring during dismantling. Before starting work, be sure to check the integrity of the wires and the absence of oxidation on the contacts.
If the sensors stop working after replacing the bumper, try the following:
- π Disconnect and reconnect the connectors until you hear a characteristic click.
- π§ Check the fuse for the parking sensors system.
- π± Carry out diagnostics using a diagnostic scanner to identify errors.
In some cases, system calibration is required, especially if the bumper was installed slightly misaligned. Sensor calibration allows the system to correctly determine the distance to obstacles and avoid false alarms.
Why can sensors beep constantly?
If the parking sensors continue to beep even without obstacles, there may be dirt or snow accumulated on their surface, or one of the sensors may be faulty. Try washing the bumper thoroughly. If the problem persists, use diagnostic equipment to disable the specific faulty sensor.
Operation and care of the new bumper
After installation and painting, the bumper requires special care in the first months of operation. It is not recommended to wash the car with high pressure (KΓ€rcher) for two weeks after painting to allow the varnish to dry completely and gain strength. You should also avoid using harsh cleaning chemicals, which can damage the fresh finish.
To preserve the appearance of the bumper, use special polishes for plastic, which create a protective layer and prevent color fading under the influence of ultraviolet radiation. Regular removal of road salt during the winter will help prevent corrosion of metal fasteners hidden under plastic.
