This bulletin applies to 2011 Mazda 2 vehicles. Some customers may complain about a slight clunk, bang or jolt from the front of the vehicle after starting the engine and as the vehicle first begins to move forward.
Explain that the noise comes from the ABS/TCS/DSC “Malfunction Detection Function” initial check. The initial check is a necessary function to ensure the normal operation of the ABS/TCS/DSC system.
The initial test function occurs during the vehicle’s first forward movement and when the vehicle reaches about 6.2 mph.
