^
When rotating the wheel fast, the fail-safe function is activated and judgment cannot be made properly. So rotate the wheel as slowly as
possible.
NOTICE: When operating it continuously, set the interval of more than 20 seconds.
(4) When the solenoids are off, depress the brake pedal again and check that the left front wheel does not rotate by hand.
If the left front wheel rotates, replace the hydraulic brake booster.
n. Inspect rear VSC solenoid (SREC) operation (step J).
HINT:
^
ON: Depress the brake pedal, activate SREC. Release the brake pedal and check that the rear wheels do not rotate.
^
OFF: Deactivate SREC and check that the rear wheels rotate.
(1) Select SRMF (SMCF, SA3) on the intelligent tester.
(2) Depress the brake pedal with stable force, then turn the SRMF (SMCF, SA3) on by the intelligent tester.
(3) Release the brake pedal when the solenoid is on, and check that the rear wheels do not rotate by hand.
If the rear wheels rotate, replace the hydraulic brake booster.
HINT:
^
To protect the solenoids, intelligent tester turns off automatically 2 seconds after every solenoid has been turned on.

NOTICE: When operating it continuously, set the interval of more than 20 seconds.
(4) When the solenoid is off, check the rear wheels by rotating them by hand.
If the rear wheels stop, replace the hydraulic brake booster.
o. Inspect rear VSC solenoid (STR) operation (step K).
HINT:
^
ON: Activate STR and SREC, then check that the rear wheels do not rotate.
^
OFF: Deactivate STR and SREC. Reactivate SREC and check that the rear wheels rotate.
(1) Select SRMR (SMCR, STR) on the intelligent tester.
(2) Turn the SRMR (SMCR, STR) on simultaneously by the intelligent tester.
(3) When the solenoids are on, check that the rear wheels do not rotate by hand.
If the rear wheels rotate, replace the hydraulic brake booster.
HINT:

If the rear wheels rotate, replace the hydraulic brake booster.
p. Inspect rear ABS solenoid (SRRH) operation (step Q).
HINT:
^
ON: Activate SRRH, depress the brake pedal, and then check that the right rear wheel rotates.
^
OFF: Deactivate SRRH, depress the brake pedal, and then check that the right rear wheel does not rotate.
(1) Select SRRH on the intelligent tester.
(2) Turn the SRRH on by the intelligent tester, then depress the brake pedal with stable force.
(3) When the solenoid is on, check the right rear wheel by rotating it by hand.
If the right rear wheel stops, replace the hydraulic brake booster.
