INSPECTION PROCEDURE

NOTICE:
When replacing the brake actuator assembly, perform zero point calibration (RAV4_ACA30 RM000001K1O00SX.html).
1.CHECK DLC3 (TC VOLTAGE)


    Toyota Rav4. Aca30, 33, 38 Gsa33 Zsa30, 35.Brake Control.Anti-Lock Brake System.Vehicle Stability Control System Tc And Cg Terminal Circuit

  1. Turn the ignition switch to ON.

  1. Measure the voltage according to the value(s) in the table below.

    Standard Voltage:
    Tester Connection
    		Switch Condition
    		Specified Condition
    E16-13 (TC) - Body ground
    		Ignition switch ON
    		11 to 14 V
