VARIOUS COMPONENTS OF TOD

A. ECU

GENERAL

Battery voltage at the ignition input will activate the

ECU.

The ECU monitors various inputs through

CAN and distributes the torque as per the vehicle

requirements. The ECU achieves this by regulating

the current to the clutch coil, which then

mechanically controls the torque distribution to the

front axle.

II. LOCATION

TOD Electronic Control Unit (ECU) is located in the

Co-driver side on to the tunnel nearer to the fire

wall.
