INSPECTION PROCEDURE

PROCEDURE

1. CHECK DLC3 (TC VOLTAGE)





(a) Turn the ignition switch ON.
(b) Measure the voltage of the DLC3.

NG -- CHECK WIRE HARNESS (DLC3 - ECM AND BODY GROUND)
OK -- Continue to next step.
2. CHECK CAN COMMUNICATION SYSTEM
(a) Check the DTC Diagnosis System.

Result





B -- REPAIR CIRCUIT INDICATED BY OUTPUT DTC
A -- REPLACE ABS AND TRACTION ACTUATOR ASSEMBLY
3. CHECK WIRE HARNESS (DLC3 - ECM AND BODY GROUND)





(a) Turn the ignition switch OFF.
(b) Disconnect the A9 ECM connector.
(c) Measure the resistance of the wire harness side connectors.
Standard resistance:






NG -- REPAIR OR REPLACE HARNESS AND CONNECTOR
OK -- Continue to next step.
4. CHECK WIRE HARNESS (DLC3 - BODY GROUND)





(a) Measure the resistance of the DLC3.
Standard resistance:






NG -- REPAIR OR REPLACE HARNESS AND CONNECTOR
OK -- Continue to next step.
5. CHECK CAN COMMUNICATION SYSTEM
(a) Check if the CAN communication DTC is output Diagnosis System.

Result
