Downloading Software And Replacing The Control Module
New software can be downloaded into the Side Obstacle Detection Control Module Left (SODL) and Side Obstacle Detection Control Module Right (SODR). When ordering software, the hardware and the software in the car is compared to the information in the Volvo central database. If the comparison is OK the software is downloaded to the control module.
If the comparison between the car and Volvo central database is not OK, the database is updated with the car configuration. When this is complete the software is downloaded.
When replacing the Side Obstacle Detection Control Module Left (SODL) respectively Side Obstacle Detection Control Module Right (SODR) download new software for them and perform calibration of the system via DIAGNOSTICS/VEHICLE COMMUNICATION/SODLR/Advanced/Calibration of Side Obstacle Detection Control Module Left (SODL) /Right (SODR).
After downloading software to the Side Obstacle Detection Control Module Left (SODL) respectively Side Obstacle Detection Control Module Right (SODR), it is important to check whether one or more of DTCs SODL-U210053, SODL-U210054, SODR-U210053 and SODR-U210054 are active. If so, calibrate the system via DIAGNOSTICS/VEHICLE COMMUNICATION/ SODLR/Advanced/Calibration of Side Obstacle Detection Control Module Left (SODL) /Right (SODR).
