5j.Torque on Demand (TOD)

“Torque-On-Demand (TOD) transfer case is a Single-speed, torque on demand transfer case. The

Torque-On-Demand system automatically and smoothly delivers four-wheel drive operation as

required, depending on the driving conditions through an ECU and patented modulating clutch

(Electromagnetic Clutch) It provides two operating positions i.e. 2H mode and Auto mode which

operates at 1:1 speed ratios. Power is transferred to the front wheel drive through a Morse HYVO

chain drive. The TOD receives inputs from the Engine ECU and ABS/ ESP ECU Via the high speed

CAN. Whenever any slippage is detected in the rear wheels (in icy roads, wet surfaces, etc.) the

torque is transferred to the front wheels by the TOD. An Electromagnetic Clutch is used to control the

amount of torque applied to the front propeller shaft. AMomentary switch is provided to activate the

TOD.This system is fully compatible with ABS/ESP System.

Salient Features

The Diagnostic Tester software for TOD is capable to communicate with ECU in the vehicle through

Serial K-Line Interface. The tester application executes all the commands supported by TOD ECU,

which helps in diagnosis of TOD ECU.

Following services are provided by the Diagnostic Tester application:

1. ECU Identification Data

2. Read ECU Parameter

3. Read DTC’s

4. Input/Output

5. Vehicle Parameter
