Checking The Hydraulic Unit Abs Operation With The Brake Tester
- Install the spare fuse to the FWD connector located in the main fuse box for models without AT VTD.
- Since the MT model and AT VTD model cannot cut off the AWD circuit, set the wheels other than the measured one on free rollers.
- Prepare for ABS sequence control.
< Ref. to ABS SEQUENCE CONTROL . >
- Set the front wheels or rear wheels on the brake tester and set the gear to "neutral".
- Operate the brake tester.
- Perform ABS sequence control.
< Ref. to ABS SEQUENCE CONTROL . >
- When the hydraulic unit begins to work, check the following work 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.WHEEL SPECIFICATION
Front wheel Rear wheel Initial value 1,000 N (102 kgf, 225 lb) 1,000 N (102 kgf, 225 lb) When depressurized 500 N (51 kgf, 112 lb) or less 500 N (51 kgf, 112 lb) or less When pressurized 1,000 N (102 kgf, 225 lb) or more 1,000 N (102 kgf, 225 lb) or more - After the inspection, depress the brake pedal and check that it is not abnormally hard, and tightness is normal.
