Checking The VDC Hydraulic Control Module (VDCH/M) Abs Operation With Brake Tester
- Prepare for ABS sequence control. <Ref. to ABS SEQUENCE CONTROL . >
- Set the front wheels or rear wheels on the brake tester and set the select lever position to the "N" range.
- Operate the brake tester.
- Perform ABS sequence control. <Ref. to ABS SEQUENCE CONTROL . >
- When the VDCH/M begins to work, check the following working sequence.
- The FL wheel performs decompression, hold and compression in sequence, and subsequently the FR wheel repeats the cycle.
- The RR wheel performs decompression, hold and compression in sequence, and subsequently the RL wheel repeats the cycle.
- Read values indicated on the brake tester and check if the fluctuation of the values between decompression and compression meets specification.FRONT AND REAR WHEEL TIRE PRESSURE SPECIFICATION
Front wheel Rear wheel Initial value 1,000 N (102 kgf, 224 lb) 1,000 N (102 kgf, 224 lb) When depressurized 500 N (51 kgf, 1121b) or less 500 N (51 kgf, 112 lb) or less When pressurized 1,000 N (102 kgf, 224 lb) or more 1,000 N (102 kgf, 224 lb) or more - After checking, press the brake pedal and check whether any irregular tightness of the brake pedal can be felt.
