INSPECTION PROCEDURE

NOTICE:
When replacing the absorber control ECU, check the acceleration sensor assembly signal after replacement (Click here).

HINT:
Check the condition of each related circuit connector before troubleshooting (Click here).

1.INSPECT TERMINAL VOLTAGE (DLC3 TC TERMINAL VOLTAGE)


    C052361E63

  1. Turn the engine switch on (IG).

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

    Voltage:
    Tester Connection
    		Condition
    		Specified Condition
    L16-13 (TC) -
    L16-4 (CG)
    		Engine switch on (IG)
    		10 to 14 V

  1. Turn the engine switch off.

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

    Resistance:
    Tester Connection
    		Specified Condition
    L16-4 (CG) - Body ground
    		Below 1 Ω



NG
Go to step 4
OK


2.CHECK HARNESS AND CONNECTOR (ECM TO DLC3)


    C110575E02

  1. Disconnect the ECM connector.

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

    Resistance:
    Tester Connection
    		Specified Condition
    A7-3 (TC) - L16-13 (TC)
    		Below 1 Ω
    L16-13 (TC) - Body ground
    		10 kΩ or higher



NG
REPAIR OR REPLACE HARNESS OR CONNECTOR (TC TERMINAL CIRCUIT)
OK


3.CHECK CAN COMMUNICATION SYSTEM

  1. Check if the CAN communication system DTC is output (Click here).

    Result:

4.CHECK HARNESS AND CONNECTOR (ECM TO DLC3)
C110575E02

  1. Disconnect the ECM connector.

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

    Resistance:
    Tester Connection
    		Specified Condition
    A7-3 (TC) - L16-13 (TC)
    		Below 1 Ω
    L16-13 (TC) - Body ground
    		10 kΩ or higher



NG
REPAIR OR REPLACE HARNESS OR CONNECTOR (TC TERMINAL CIRCUIT)
OK


5.CHECK HARNESS AND CONNECTOR (DLC3 TO BODY GROUND)


    C052361E64

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

    Resistance:
    Tester Connection
    		Specified Condition
    L16-4 (CG) - Body ground
    		Below 1 Ω



NG
REPAIR OR REPLACE HARNESS OR CONNECTOR (GND CIRCUIT)
OK


6.CHECK ECM (DLC3 TC TERMINAL INPUT)


    C052361E63

  1. Using the SST, connect the terminals TC and CG of the DCL3.

SST
09843-18040  

  1. Check that the engine, ABS, and VSC warning lights are blinking.

    Result:
    Result
    		Proceed To
    Warning lights are blinking
    		A
    Warning lights are not blinking
    		B



B
REPLACE ECM
