HINT: To protect the solenoids, hand-held tester turns OFF automatically 2 seconds after every solenoid has been turned ON.
5) When the solenoids are OFF, check that the brake pedal can be depressed. If the pedal cannot be depressed, replace the brake master
cylinder.
6) Once, release the brake pedal. After depressing and holding the brake pedal with stable force, turn the SFLH and SFLR solenoids ON
simultaneously.

h) Jack up and support the vehicle.
i)
Release the parking brake lever.
j) Shift the transfer shift lever to "N" position and check the rear wheels by rotating them by hand.
k) Inspect the rear TRAC & VSC solenoid operation.
1) Select "SA3" and "STR" on the hand-held tester.
2) Turn "SA3" and "STR" ON simultaneously with the hand-held tester, and check that the rear wheel does not rotate by hand.
HINT: 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. If the rear wheels rotate, replace the brake master cylinder.
3) Turn "SA3" and "STR" OFF simultaneously, and check that the rear wheels by rotating them by hand.
