 Show As safety technology progresses, driver-assistance features (ADAS) such as Blind Spot Monitor (BSM) are becoming more widely equipped in new cars. Now, BSM can be found in the Perodua Ativa and many of the B-segment cars currently on sale. How does it work?Not all Blind Spot Monitor systems use the same detection method but the common solution is via radar sensors mounted at the rear, usually inside the rear bumper. Some systems may employ cameras as well. Should the sensors detect an object, it’ll relay the signal to the system for notification, which can be in the form of audio or visual. Chimes or buzzers may alert or warning indicators may light up in the side mirrors or on the A-pillar next to the mirror. What do manufacturers call it?Brands like Toyota and Volkswagen call it Blind Spot Monitor; BMW calls it Blind Spot Detection; Mercedes-Benz calls it Blind Spot Assist; Volvo calls it Blind Spot Information System; and the list goes on. Despite how manufacturers name their systems, all of them refer to the same feature. My car has it, anything I should know?Since we have the Perodua Ativa with no where to go for now, we decided to flip through the half-a-thousand pages owner’s manual and found some interesting titbits. For one, the manual suggests that owners should keep the area of the rear bumper surrounding the sensors clean. It adds that the system may stop functioning if there are rain drops or dirt on the rear bumper around the sensors. This would also mean that the system wouldn’t be as effective in the rain, as with most functions of ADAS. Note that the visible sensors are the reverse sensors, BSM sensors are hidden.Owners are advised to have the vehicle inspected at an authorised service centre if:
It even warns owners against changing the colour of the bumper. ConclusionFeatures like BSM are helpful towards drivers but the key point to take away from here is that its function can easily be impaired, and one needs to ensure it is in fully working condition. But as we always say, features like BSM are just a tool to help drivers and can never be fully relied on. As drivers, it is our duty to drive safely and responsibly.

The first time it lasted a day and a half which happened maybe a month or so ago. Then recently when I went to leave for work in the morning it came on again but then was off again when I left 8hrs later. so last saturday (June 6) I took my car in for an oil change and to have the problem checked. They ran computer codes and found it saying there was something wrong and said to dig further it would cost $240 which would go towards the repair. I ended up having to leave it for them to complete the diagnostic. So now to this past monday they got back to me and what they found was corrosion along the main wireing harness connector which is causing communication loss with the left rear BSM module. Now what they wanted to do which they said was the cheaper option is replace the connector and wires since that more then likely is what causing the problem which would cost me around $760 labor included and the $240 taken off from the diagnostic, if that doesnt work which they said it may or may not fix the problem they want to replace the Module. Now I had them call and talk to extended warranty and said they would cover the cost of the module if it needed to be changed (module being $625) I'd just have to pay the deductible which for me is $100 but they would have to do the wiring thing first which they would not cover. Now the extended warranty that I have is totalcare via Easycare which is supposed to cover everything from my understanding so thats the situation, has anyone ever heard of this popping up before? They even said this is something they haven't seen before. I guess my main concern is if it is fixed would this be something that would happen again, since I don't want to keep throwing money at the problem. Last edited by That3DGuy; 06-15-2015 at 12:19 AM. Join Date: Nov 2012 Location: Northern Calif. Posts: 627 So much for non-OEM extended warranties! Join Date: Jun 2015 Location: California Posts: 12 Ugh, that sucks. Why would the extended warranty NOT cover the replacement of the wiring? Since that could very well be the only problem, I'd think they'd jump at that instead of waiting for a potentially costlier fix? I'd push on the warranty guys, that sounds bogus...either that or i'd drop that "extended warranty" completely. Oh, and I haven't seen this anywhere, and hope it doesn't happen to mine. Good luck with the fix. Junior Member Thread Starter Join Date: Jun 2015 Location: VA Posts: 2 I agree! I think before I take it back to get it fixed I'm going to call and talk to the extended warranty people myself because that does sound weird to me. Especially since my coverage is supposed to cover everything from what I understand. Join Date: Sep 2014 Posts: 4 I was wondering if it is a corrosion problem. Warranty is longer for that.

The following systems also use the radar sensors (rear). The radar sensors (rear) are installed inside the rear bumper, one each on the left and right sides.
Where is the blind spot detection sensor located?The Blind Spot Monitoring (BSM) system uses two radar-based sensors, located inside the rear bumper fascia, to detect highway licensable vehicles (automobiles, trucks, motorcycles, etc.)
What does check blind spot system mean?Blind Spot Warning (BSW): This detects vehicles in the blind spot while driving and notifies the driver to their presence. Some systems provide an additional warning if the driver activates the turn signal when it is unsafe to merge or change lanes.
