INSPECTION PROCEDURE

PROCEDURE

1. CHECK DLC3 (TC VOLTAGE)

(a) Disconnect the S1 skid control ECU connector.
(b) Measure the resistance of the wire harness side connectors.
Standard resistance:






NG -- REPAIR OR REPLACE HARNESS AND CONNECTOR
OK -- REPLACE BRAKE ACTUATOR ASSEMBLY
3. 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.
4. CHECK WIRE HARNESS (SKID CONTROL ECU - DLC3)





(a) Disconnect the S1 skid control ECU connector.
