DTC P0730 BELT DAMAGEPFP:31935
DescriptionBCS001IB
TCM selects the gear ratio using the engine load (throttle position), the primary pulley revolution speed, and
the secondary pulley revolution speed as input signal. Then it changes the operating pressure of the primary
pulley and the secondary pulley and changes the groove width of the pulley.
CONSULT-II Reference ValueBCS001IC
Remarks: Specification data are reference values.

TCM calculates the actual gear ratio with input speed sensor (primary speed sensor) and output speed
sensor (secondary speed sensor).
