INSEPCTION PROCEDURE

PROCEDURE

1. CHECK DLC3 (TC VOLTAGE)





(a) Turn the ignition switch ON.

(b) Measure the voltage of the DLC3.

Standard voltage:





NG -- CHECK WIRE HARNESS (SKID CONTROL ECU - ECM)
OK -- Continue to next step.

2. CHECK CAN COMMUNICATION SYSTEM

(a) Check the DTC Reading and Clearing Diagnostic Trouble Codes.

Result





B -- REPAIR CIRCUITS INDICATED BY OUTPUT DTCS

A -- REPLACE SKID CONTROL ECU

3. CHECK WIRE HARNESS (SKID CONTROL ECU - ECM)





(a) Disconnect the E6 ECM connector.

(b) 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 wire harness side connector.

Standard resistance:





NG -- REPAIR OR REPLACE HARNESS AND CONNECTOR
OK -- Continue to next step.

5. CHECK CAN COMMUNICATION SYSTEM

(a) Check the DTC Reading and Clearing Diagnostic Trouble Codes.

Result





B -- REPAIR CIRCUITS INDICATED BY OUTPUT DTCS

A -- REPLACE SKID CONTROL ECU
