TCCU Pin Numbers and Description
T/C: Transfer Case
This is a terminal that outputs the input signal to the T/C motor during
the 4WD switch operation. When switching the 2WD mode to 4WD
mode, the battery power is supplied to “Motor Hi-Lo” and the opposite
side is earthed, and vice versa.

These lines are sharing the information among the related units
through the CAN communication. The differences from the conven-
tional part time T/C models are that the speed sensing type tone
wheel in T/C has been eliminated and the speed signal comes from
the ABS/ESP HECU or the instrument panel.

Supplying the voltage to clutch coil for all shifting operations
• When supplying power: Battery voltage
• When no power supplied: Ground power
