ABS/TCS
OUTLINEA6E692146444201•The construction and operation of ABS (ABS/TCS) is the same as that of the current Mazda6 (GG) L8, LF, L3
engine 2WD model, except for the following. (See Mazda6 Training Manual 3359-1*-02C.)
—Due to adoption of TCM, ABS (ABS/TCS) HU/CM sends 4-wheel speed signal to the TCM through CAN.

DYNAMIC STABILITY CONTROL
OUTLINEA6E692067650201•The construction and operation of DSC is the same as that of the current Mazada6 2WD model, except for the
following:
— Due to the addition the 4WD model, DSC HU/CM uses the foward-G signal from the combine sensor to
control DSC.
—Due to adoption of the 4WD CM, DSC HU/CM sends a coupling torque request, a 4-wheel speed, and DSC
operation condition signal to the 4WD CM through CAN.
—Due to the adoption of TCM, DSC HU/CM sends a 4-wheel speed signal to the TCM through CAN.
