(k) Check the rear TRAC & VSC solenoid operation. (1) Select the "SA3" and "STR" on the intelligent tester. (2) Turn the "SA3" and "STR" ON simultaneously with the intelligent tester, and check that the rear wheels do not rotate by hand. HINT: When rotating the wheel fast, the fail-safe function is activated and judgement cannot be made properly. So rotate the wheel as slowly as possible. If the rear wheels rotate, replace the hydraulic brake booster. (3) Turn the "SA3" and "STR" OFF simultaneously, and check that the rear wheels rotate by hand. HINT: To protect the solenoids, the intelligent tester turns OFF automatically 2 seconds after every solenoid has been turned ON.
When rotating the wheel fast, the fail-safe function is activated and judgement cannot be made properly. So rotate the wheel as slowly as possible. NOTICE: When operating the solenoid continuously, set the interval of more than 20 seconds. If the rear wheels do not rotate, replace the hydraulic brake booster. (l) Check the right rear ABS solenoid. (1) Select the "SA3", "STR" and "SRRH" on the intelligent tester. (2) Turn the "SA3", "STR" and "SRRH" ON simultaneously with the intelligent tester, and check that the right rear wheel rotates by hand. HINT: To protect the solenoids, the intelligent tester turns OFF automatically 2 seconds after every solenoid has been turned ON.
When rotating wheel fast, the fail-safe function is activated and judgement cannot be made properly. So rotate the wheel as slowly as possible. When solenoid is OFF, the wheel might stop temporarily. However if the wheel rotates again, the function works normally. If the right rear wheel does not rotate, replace the hydraulic brake booster. (3) Turn the "SA3", "STR" and "SRRH" OFF, and check that the right rear wheel rotates by hand. HINT: To protect the solenoids, the intelligent tester turns OFF automatically 2 seconds after every solenoid has been turned ON. When rotating wheel fast, the fail-safe function is activated and judgement cannot be made properly.
So rotate the wheel as slowly as possible. If the right rear wheel does not rotate, replace the hydraulic brake booster. (4) Depress the pedal with stable force, then turn the "SRRH" and "SRRR" ON simultaneously. (5) When the solenoids are ON, check that the right rear wheel by rotating it by hand. (m) Check the left rear ABS solenoid operation. (1) Select the "SA3", "STR" and "SRLH" on the intelligent tester. (2) Turn the "SA3", "STR" and "SRLH" ON with the intelligent tester, and check that the left rear wheel rotates by hand. HINT: When rotating the wheel fast, the fail-safe function is activated and judgement cannot be made properly. So rotate the wheel as slowly as possible.
If the left rear wheel does not rotate, replace the hydraulic brake booster. (3) Turn the "SA3", "STR" and "SRLH" OFF, and check that the left rear wheel rotates by hand. HINT: To protect the solenoids, the intelligent tester turns OFF automatically 2 seconds after every solenoid has been turned ON. When rotating the wheel fast, the fail-safe function is activated and judgement cannot be made properly. So rotate the wheel as slowly as possible. When solenoids are OFF, the wheel might stop temporarily. However if the wheel rotates again, the function works normally. If the left rear wheel does not rotate, replace the hydraulic brake booster.
(4) Depress the pedal with stable force, then turn the "SRLH" and "SRLR" ON simultaneously. HINT: To protect the solenoids, the intelligent tester turns OFF automatically 2 seconds after every solenoid has been turned ON. (5) When the solenoids are ON, check that the left rear wheel by rotating it by hand. HINT: When rotating the wheel fast, the fail-safe function is activated and judgement cannot be made properly. So rotate the wheel as slowly as possible. (n) Lower the vehicle. (o) Disconnect the intelligent tester. 3. CHECK HYDRAULIC BRAKE BOOSTER OPERATION (Using ABS Actuator Checker) cardia gn
