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.

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.

Diagnostic Help
Brake diagnosis involves determining if the concern is related to a mechanical, hydraulic, electrical or vacuum oper-
ated component.
NOTE :
The brake reservoir fluid level will decrease in proportion to normal lining wear.
NOTE :
Brake fluid tends to darken over time. This is normal and should not be mistaken for contamination.
Preliminary Brake Check:
•Check the condition of the tires and wheels. Damaged wheels and worn, damaged or under inflated tires can
cause a pull, shudder, vibration and a condition similar to brake grab.
• If a complaint was based on noise while braking, check the suspension components. Jounce the front and the
rear of vehicle and listen for anything that might be caused by a loose, worn or damaged suspension or steer-
ing component.
• Inspect the brake fluid level and condition.
1. If the fluid level is abnormally low, look for any evidence of leaks at the calipers, brake lines, master cyl-
inder and at the Antilock Brake System (ABS) Hydraulic Control Unit (HCU).
2. If the fluid appears to be contaminated, drain a sample to examine.
• The system will have to be flushed if the fluid is separated into layers, or contains a substance other than
brake fluid. The system seals, cups, hoses, master cylinder and HCU will also have to be replaced after flush-
ing. Use clean brake fluid to flush the system.
• Check the parking brake operation. Verify free movement and full release of the cables and the lever. Also note
if the vehicle was being operated with the parking brake partially applied.
• Check the brake pedal operation. Verify that the pedal does not bind and has adequate free play. If the pedal
lacks free play, check the pedal and the power booster for looseness or for a binding condition. DO NOT road
test the vehicle until the condition is located and corrected.
• Check the vacuum booster check valve and vacuum supply hose.
• If the preliminary checks appear to be OK, road test the vehicle.

CONDITION POSSIBLE CAUSES CORRECTION
Disc Brake Chirp · Excessive brake rotor runout.
