by checking the brake torque fluctuation of the wheel controlled by the ABS.
11. Turn the Mode Selector switch to "3", "4" and "5". Perform step 10 for each of the test mode positions.
Operation Sequence Simulated by Modes of ALB Checker
NOTE: The wheel sensors and sensor wire harnesses are not checked by the ALB checker.
Operation Sequence simulated by Modes of ABL Checker.
Mode 1: Sends the simulated driving signal 0 mph (0 km/h) 113 mph (180 km/h) 0 mph (0 km/h) of each wheel to the ABS control unit to check the
system under the normal driving. There should be no kickback.
Mode 2: Sends the driving signal of each wheel, then sends the lock signal of the left-rear wheel to the ABS control unit to check the system under
left-rear wheel lock. There should be kickback.
Mode 3: Sends the driving signal of each wheel, then sends the lock signal of the right-rear wheel to the ABS control unit to check the system under
right-rear wheel lock. There should be kickback.
Mode 4: Sends the driving signal of each wheel, then sends the lock signal of the left-front wheel to the ABS control unit to check the system under
left-front wheel lock. There should be kickback.
Mode 5: Sends the driving signal of each wheel, then sends the lock signal of the right-front wheel to the ABS control unit to check the system under
right-front wheel lock. There should be kickback.
Inspection Points
If the ABS indicator light comes on and the system stops during the inspection, confirm the ABS code and perform the appropriate troubleshooting for
the code. If there is no kickback in modes 2 through 5, and the ABS indicator light does not come on, the following items are probable causes:
-
Pressure switch stuck ON
-
Clogged or stuck solenoid outlet valve
-
Modulator wire harness connectors improperly connected
Modulator Function Check
NOTE: This inspection determines whether the basic brake system continues to operate normally when the modulator unit fluid pressure is low.
CAUTION:
-
This inspection is made by relieving the high-pressure fluid in the modulator unit and checking for brake operation. After inspection, be sure to
add fresh brake fluid to the specified level of the reservoir, and start the engine to restore the ABS to its normal operating condition.
-
Do not spill brake fluid on the car; it may damage the paint; if brake fluid does contact the paint, wash it off immediately with water.
-
Do not reuse the drained brake fluid.
-
Do not loosen the relief plug on the accumulator.
1. Remove the bleeder cap from the maintenance bleeder on the modulator unit.
2. Attach the wrench to the maintenance bleeder.
3. Connect a rubber tube of the appropriate diameter to the maintenance bleeder, and set the other end of the rubber tube in a suitable container.
