Torque on Demand (T.O.D) System

Description and Operation
Voltage is applied with the starter switch in ON or START through the ELEC. IGN. fuse CB-4. The T.O.D. control unit receives input from the front speed sensor (transfer) and the rear speed sensor (transfer) and determines if there is any variation. In the event of a variation in speeds, voltage is applied to the clutch solenoid (transfer) to apply torque to the front wheels. While voltage is being applied to the clutch solenoid (transfer), the T.O.D. control unit is providing ground to the corresponding indicators in the meter assembly. The T.O.D. control unit receives input from the throttle position sensor (TPS) in order to determine acceleration and deceleration conditions. The T.O.D. control unit receives an input from the ABS system, when active, to apply voltage to the clutch solenoid (transfer).
