Troubleshooting RCTA and BSM Issues
Blind Spot Monitoring Sensors Under Side Mirror
The most efficient way to troubleshoot RCTA and BSM related issues is usually with a quality OBD-II diagnostic tool.
This type of scanner can read all active or stored errors related to the BSM module. This will allow you to identify the root cause of the error and repair it efficiently.
During these inspections, it is also a good idea to check the individual sensors to ensure they are not dirty or clogged in any way. Finally, it is also important to check the condition of the vehicle’s battery and starting and charging systems.
Even minor voltage fluctuations can wreak havoc on BSM-related systems, causing feedback and connection issues that are difficult to pinpoint. In these cases, there is no chance of any major issues other than a bad battery.
When to go to the dealer
In many cases, diagnosing and repairing RCTA and BSM-related issues is best left to the professionals after making sure all sensors are clean and there are no obvious clogs.
This is because these types of systems tend to be relatively complicated and may require specialized tools to repair. If in doubt, we recommend the help of a professional, especially if the cause of such a problem is not clear.
How to manually turn off RCTA or BSM
In most cases, cross traffic and rear blind spot monitoring technology is useful, but there may be situations such as: when towing, driving off-road, or in narrow, congested areas, you may need to temporarily disable this technology to avoid unnecessary warnings and distractions.
The method for manually disabling the RTCA and/or BSM system generally varies depending on the make and model of the vehicle. Multi-information display in Toyota and Lexus vehicles. Alternatively, some vehicles have a simple toggle or button switch that turns the system on or off.
Do these systems use the same sensors?In most cases, today’s vehicles actually use the same sensors to enable RCTA and BSM systems to operate. All of these types of systems use their own radar sensors that provide critical feedback to various control modules.
