I have this car with Blind spot message, i scan the system but failed to get any info relating to this, checking on the scan tool among Volvo multi controllers list, there is no controller name BLIS or blind spot module...

This car come with camera fitted to the driving mirror, now when i scan all controllers all things were okay except PDM which has rear right window failure, please i want to know how to solve this problem in other to get the message off, i look on wiring schematics but there is no related info about it, so please help me which module has this incorporate blind spot and what must i check out for... because the panel or cluster has this message display continuously.
