INSPECTION PROCEDURE

NOTICE:
When replacing the brake actuator assembly, perform zero point calibration (CAMRY_ACV40 RM000000XHR03AX.html).
1.CHECK CAN COMMUNICATION SYSTEM

  1. Check if the CAN communication system DTC is output (CAMRY_ACV40 RM000000WIB05NX.html for LHD, or CAMRY_ACV40 RM000000WIB05SX.html for RHD).

    Result:

    Condition
    		Proceed to
    DTC is not output
    		A
    DTC is output
    		B

  1. Turn the ignition switch on (IG).

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

    Standard voltage:
    Tester Connection
    		Condition
    		Specified Condition
    E10-13 (TC) - E10-4 (CG)
    		Ignition switch on (IG)
    		10 to 14 V


OK
Go to step 5

5.CHECK ECM (TC of DLC3 INPUT)


    Camry. Acv40 Gsv40.Brake Control.Anti-Lock Brake System.Vehicle Stability Control System Tc And Cg Terminal Circuit

  1. Turn the ignition switch off.

  1. Reconnect the ECM connector.

  1. Using SST, connect terminals TC and CG of the DLC3.

  1. Turn the ignition switch on (IG).

  1. Check that the check engine warning light is blinking.

    Result:

    Condition
    		Proceed to
    Check engine warning light is blinking
    		A
    Check engine warning light is not blinking
    		B
    HINT:
    If troubleshooting has been carried out according to the Problem Symptoms Table, refer back to the table and proceed to the next step before replacing the part (CAMRY_ACV40 RM000000XHN04RX.html).
