Just a Test Noise

This bulletin applies to 2011 Mazda2 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.

This is a normal operating noise of the ABS.

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.
