Checking The VDC Hydraulic Control Module (VDCH/M) Abs Operation With Brake Tester
- Prepare for operating the ABS sequence control. < Ref. to ABS Sequence Control . >
- Set the front wheels or rear wheels on brake tester and set the select lever position to "N" range.
- Operate the brake tester.
- Perform the ABS sequence control. < Ref. to ABS Sequence Control . >
- When the VDCH/M begins to work, check the following working sequence.
- FL wheel performs decompression, holding, and compression in sequence, and subsequently FR wheel repeats the cycle.
- RR wheel performs decompression, holding, and compression in sequence, and subsequently RL wheel repeats the cycle.
- Read values indicated on the brake tester and check if fluctuation of values meet the standard values when decompressed and compressed.WHEEL SPECIFICATIONS
