Downloaded from www.Manualslib.com manuals search engine The Tiggo 4WD is the first 4WD vehicle produced by Chery. The 4WD system is equipped with a QR523T transaxle
manufactured by Chery.
An active torque transfer system is used, and an interactive torque management system (ITM) is equipped to make
it possible to intelligently distribute the drive force for the front wheels and rear wheels according to different road
conditions. For example, on a smooth road, the vehicle utilizes front-wheel drive. When road conditions worsen, the
ITM will automatically switch to 4WD. The use of ITM allows the Tiggo vehicle to be more economical and more
efficient than the common 4WD system.
Operation
The intelligent 4WD system is controlled by an interactive torque management system (ITM) module. The ITM mod-
ule communicates with the Engine Control Module (ECM) and the Antilock Brake System (ABS) controller through the
CAN network. The ITM module collects data from sensors on the vehicle body to determine the condition of the drive
wheels. Based on the sensor inputs, the ITM module controls the ITM controller. The ITM controller will then distrib-
ute a portion of the torque to the rear drive axle as needed. The ITM controller works as an electromagnetic clutch.
Different torque can be transferred by changing the electric current of the ITM controller. The ITM controller will be
able to distribute the torque of the front drive axle and the rear drive axle at different ratios according to the various
dynamic conditions of the vehicle.

Description
The ITM control module is located under the driver seat.
Operation
The ITM control module collects signals from the Engine Control Module (ECM) and Antilock Brake System (ABS)
controller, judges the vehicle driving state, controls the working electric current of the ITM controller and distributes
the torque of the front axle and the rear axle intelligently according to such signals.
Removal & Installation
1. Disconnect the negative battery cable.
2. Adjust the left front seat fully backward.
3. Remove the ITM control module mounting bolts.
4. Remove the ITM control module electrical connec-tor.
5. Remove the ITM control module (1).
6. Installation is in the reverse order of removal.

Downloaded from www.Manualslib.com manuals search engine WARNING!
Do not remove the strut rod nut while the strut assembly is installed in the vehicle, or before the coil spring is
compressed with a spring compressor. The spring is held under high pressure and must be compressed before
the strut rod nut can be removed.
CAUTION:
At no time when servicing a vehicle can a sheet metal screw, bolt, or other metal fastener be
installed in the shock tower to replace the original plastic clamp. It may come in contact with the
strut or coil spring.
CAUTION:
The wheel bearing will be damaged if the vehicle is rolled with the axle shaft hub nut loose.
Operation
The front suspension utilizes a MacPherson strut system. This suspension system incorporates a strut assembly that
takes the place of the upper arm and ball joint. The strut performs the function of a shock absorber and is encom-
passed by a coil spring.
