ON-VEHICLE INSPECTION
1. CHECK BRAKE ACTUATOR OPERATION
(a) Pre-check preparation
(1) Move the shift lever to the P position. Apply the parking brake and connect the intelligent tester or Techstream to the DLC3.
(2) Turn the power switch ON (IG).
(3) Turn on the intelligent tester. Select "MAS CYL PRESS 1", "MAS CYL PRESS 2", "FR W/C SENS", "FL W/C SENS", "RR W/C
SENS", and "RL W/C SENS".
(4) Turn on the Techstream. Select "Voltage of Master Cylinder Sensor", "Voltage of Master Cylinder Sensor 2", "FR Wheel Cylinder
Pressure Sensor", "FL Wheel Cylinder Pressure Sensor", "RR Wheel Cylinder Pressure Sensor", and "RL Wheel Cylinder Pressure
Sensor".
(b) Intelligent tester:
(1) Check the FR system solenoid (SLAFR CUR, SLRFR CUR, SMC1, SMC2).
-
Select "SLAFR CUR". Press "->" and check the output voltage.
(c) Techstream:
(1) Check the FR system solenoid (SLAFR Solenoid Current, SLRFR Solenoid Current, Electronically Controlled Brake System Solenoid
(SMC1), Electronically Controlled Brake System Solenoid (SMC2)).
-
Select "SLAFR Solenoid Current". Press "->" and check the output voltage.
NOTE: Do not depress the brake pedal.
HINT: It takes approximately 35 seconds to complete the check.
Standard voltage:
Intelligent tester
Techstream
If incorrect, troubleshoot the brake system See: Testing and Inspection.
(d) Intelligent tester:
(1) Check the FL system solenoid (SLAFL CUR, SLRFL CUR, SMC1, SMC2).
-
Select "SLAFL CUR". Press "->" and check the output voltage.
(e) Techstream:
(1) Check the FL system solenoid (SLAFL Solenoid Current, SLRFL Solenoid Current, Electronically Controlled Brake System Solenoid
(SMC1), Electronically Controlled Brake System Solenoid (SMC2)).
