ON-VEHICLE SERVICE

ABS Bleeding

The bleeding procedures for brake system with X-431 3G diagnostic tester are as follows:
1. Make sure all brake lines are installed and tightened properly.
2. Check that battery voltage is normal.
3. Turn ignition switch to LOCK.
4. Connect X-431 3G diagnostic tester (the latest software) to Data Link Connector (DLC).
5. Turn ignition switch ON.
6. Using X-431 diagnostic tester, record and clear the DTCs stored in ABS control module assembly.
7. Using X-431 3G diagnostic tester, enter Brake Control System, select Repair Bleed Function, and then

perform operation according to the information and procedures displayed on the diagnostic tester.

HINT:

 If the bleeder plug is open, never depress the brake pedal repeatedly. Doing so will increase the

amount of air in the system.

 Do not drain brake fluid from the brake fluid reservoir while bleeding the system. Otherwise, low fluid

level in the brake reservoir will cause additional air to enter the brake system.

 Always check the brake fluid level at all times to ensure that brake fluid level in the brake reservoir is

always close to the "MAX" level.

8. For X type brake circuit, the bleeding order is: rear left wheel, front left wheel, front right wheel, rear right

wheel.

9. After bleeding is completed, fill the brake reservoir with brake fluid to the "MAX" level .
10.Drive the vehicle to perform a road test, and confirm that the ABS system operates normally and brake

pedal feel is good.

WARNING

 When bleeding the brake system, wear safety glasses. If brake fluid gets on your eyes or skin, wash off

with water completely.

 DO NOT drop brake fluid onto the body paint, as brake fluid can corrode the body paint.

CAUTION

 Brake fluid should meet the Chery specified type (DOT 4). DO NOT mix the brake fluid with other types

of brake fluid.

 Brake fluid has strong water absorbability, be sure to place it in the original sealed container.
 To prevent dust and other foreign matter from entering the reservoir, wipe it off before removing the

reservoir cap.

connector, move the connector lock bracket upward
and disconnect the ABS control module assembly
connector (arrow).

pipe coupling plugs (arrow).



(Tightening torque: 16 ± 2 N·m)

WARNING

 When repairing ABS system, first release the pressure of high pressure brake fluid in the accumulator, to

prevent the high pressure brake fluid from spraying out and causing injury.

 Operation procedures: turn ignition switch off first, and then depress and release brake pedal repeatedly

until brake pedal becomes hard.

 In addition, never turn the ignition switch on before the ABS system is installed completely to prevent the

hydraulic pump from energizing and running.

CAUTION

 Wash off brake fluid immediately if it comes in contact with any paint surface.

ENVIRONMENTAL PROTECTION

 Drained brake fluid should be well kept in a container. Never discard it at will.
