INSPECTION PROCEDURE

NOTE: When replacing the ABS & TRACTION actuator assembly, perform zero point calibration Programming and Relearning.

PROCEDURE

1. INSPECT DLC3 TERMINAL VOLTAGE (TC TERMINAL VOLTAGE)





(a) Turn the ignition switch on (IG).
(b) Measure the voltage according to the value(s) in the table below.
Voltage:





(c) Measure the resistance according to the value(s) in the table below.
Resistance:






NG -- CHECK HARNESS AND CONNECTOR (ECM TO DLC3)
OK -- Continue to next step.

2. CHECK HARNESS AND CONNECTOR (ECM TO DLC3)





(a) Disconnect the ECM connector.
(b) Measure the resistance according to the value(s) in the table below.
Resistance:





(c) Measure the resistance according to the value(s) in the table below.
Resistance:






NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR (TC TERMINAL CIRCUIT)
OK -- Continue to next step.

3. CHECK CAN COMMUNICATION SYSTEM
(a) Check if the CAN communication system DTC is output Diagnosis System.
Result:





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 Problem Symptoms Table.

B -- REPAIR CIRCUIT INDICATED BY OUTPUT CODE
A -- REPLACE ABS & TRACTION ACTUATOR ASSEMBLY
4. CHECK HARNESS AND CONNECTOR (ECM TO DLC3)





(a) Disconnect the ECM connector.
(b) Measure the resistance according to the value(s) in the table below.
Resistance:





(c) Measure the resistance according to the value(s) in the table below.
Resistance:






NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR (TC CIRCUIT)
OK -- Continue to next step.

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





(a) Measure the resistance according to the value(s) in the table below.
Resistance:






NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR (GND CIRCUIT)
OK -- Continue to next step.

6. CHECK ECM (DLC3 (TC) INPUT)





(a) Using SST, connect the terminals TC and CG of the DLC3.
SST: 09843-18040
(b) Check that the engine warning light is blinking.
Result:





B -- REPLACE ECM
A -- Continue to next step.

7. CHECK CAN COMMUNICATION SYSTEM
(a) Check if the CAN communication system DTC is output Diagnosis System.
Result:





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 Problem Symptoms Table.

B -- REPAIR CIRCUIT INDICATED BY OUTPUT CODE
A -- REPLACE ABS & TRACTION ACTUATOR ASSEMBLY
