Hi there,

The fault 00532 Supply Voltage B+ in your airbag control module indicates that low battery voltage was detected by the airbag control module. There are many components of airbag systems (also known as SRS, which stands for Safety Restraint Systems) in modern cars. There are several crash sensors located throughout the vehicle which transmit signals to the control module. From there the control module sends signals to different safety devices such as airbags and seat belt tensioners. Because this is such a critical safety system, it is extremely sensitive too inconsistencies or spikes in voltage, which is why your airbag control module stored a fault when it detected low battery voltage. The most common cause of this is a weak vehicle battery. If you have ever had to jump start it or it was slow to start, that is most likely when the battery voltage dropped below specification and stored this fault.

This is also very likely cause of the ABS system fault as well, since that system is also sensitive to voltage changes. I recommend that you have a qualified technician, such as one available from YourMechanic, to come to you and properly load test the battery and replace it if necessary. After having this service performed you can have the technician clear and recheck the ABS faults to see if any additional work needs to be performed.
