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.

Description
The front suspension system incorporates a strut assembly that takes the place of the upper control arm and upper
ball joint. The strut carries out the function of a shock absorber and is encompassed by a coil spring. The strut
assembly supports the weight of the vehicle and is also the pivot point for the steering knuckle. This system uses a
lower control arm and ball joint for the lower pivot point of the steering knuckle.

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.

Description
A MacPherson type strut assembly is used in place of the traditional front suspension upper control arm and upper
ball joint. The bottom of the strut mounts directly to the steering knuckle using two attaching bolts and nuts going
through the strut clevis bracket and steering knuckle. The top of the strut mounts directly to the strut tower of the
vehicle using the three threaded studs on the strut assembly’s upper mount.

The strut assembly cushions the ride of the vehicle, controlling vibration, jounce and rebound of the suspension. The
coil spring controls ride quality and maintains proper ride height. The spring isolators isolate the coil spring at the top
and bottom from coming into metal-to-metal contact with the upper mounting seat and the strut. The strut dampens
jounce and rebound motions of the coil spring and suspension.
Diagnosis & Testing
Before removing the front strut, perform the following to test the front strut functionality:
•Adjust the tire pressure to all tires to proper specifications.
• Push and shake the front of the vehicle three or four times with identical force every time
• During the pushing and recoiling, the resistance and recoil times of the vehicle should be equal.
• If the strut (shock absorber) functions properly, the vehicle will recoil several times and then stop recoiling after
the pushing force is removed.
Removal & Installation
1. Raise and support the vehicle.
2. Remove the wheel mounting nuts and the wheel assembly.
(Tighten: Wheel mounting nuts to 110 N·m)
3. Disconnect the brake fluid hose clamp (1) from the brake fluid hose bracket on the front strut.
4. Remove the brake fluid hose from the bracket.
5. Remove the wheel speed sensor wire.
6. Remove the nut (1) from the front stabilizer bar link bracket on the front strut.
(Tighten: Front stabilizer bar link bracket nut to
48 ± 6 N·m)

Downloaded from www.Manualslib.com manuals search engine Front Coil Spring
Description
A coil-over front strut assembly supports each front coil spring. The top of the strut assembly mounts to the strut
tower.
Operation
Coil springs are designed to store energy and subsequently release it and to absorb shock and maintain a force
between contacting surfaces. Coil springs are rated for specific vehicle applications.
NOTE :
Each component is serviced by removing the strut assembly from the vehicle and disassembling it. Coil springs are
rated separately for each corner or side of the vehicle depending on optional equipment and type of vehicle service.
If a coil spring requires replacement, be sure that it is replaced with a spring meeting the correct load rating for the
vehicle and its specific options.
Removal & Installation
CAUTION:
At no time when servicing a vehicle can a sheet metal screw, bolt or other metal fastener be
installed into the strut tower to take the place of an original plastic clamp. Also, do not drill holes
into the front strut tower for the installation of any metal fasteners into the strut tower area indi-
cated.
1. Raise and support the vehicle.
2. Remove the front strut assembly (See Front Strut Removal & Installation in Section 10 Suspension).
WARNING!
Do not remove the strut rod nut before the coil spring is properly compressed. The coil spring is held under
pressure. The coil spring must be compressed, removing spring tension from the upper mount and bearing,
before the strut rod nut is removed.
3. Position the strut assembly in the strut coil springcompressor following the manufacturer’s instruc-
tions and set the lower and upper hooks of the
compressor on the coil spring.
4. Compress the coil spring until all coil spring tension is removed from the upper mount and bearing.
5. Once the spring is sufficiently compressed, install the strut nut wrench on the strut rod nut.
6. Install a deep socket on the end of the strut rod.
