INSPECTION PROCEDURE

1.CHECK DTC (ELECTRONICALLY CONTROLLED BRAKE SYSTEM)

  1. Check the electronically controlled brake system (Click here).

    OK:
    DTC is not output.



NG
GO TO FLOW CHART
OK


2.CHECK HARNESS AND CONNECTOR (STEERING SENSOR - AFS ECU)


    E069256E02

  1. Disconnect the steering sensor connector and AFS ECU connector.

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

    Resistance:
    Tester connection
    		Condition
    		Specified condition
    SS1- (S10-7) - SS- (A17-8)
    		Always
    		Below 1 Ω
    SS1+ (S10-8) - SS+ (A17-7)
    		Always
    		Below 1 Ω
    SS- (A17-8) - Body ground
    		Always
    		10 kΩ or higher
    SS+ (A17-7) - Body ground
    		Always
    		10 kΩ or higher



NG
REPAIR OR REPLACE HARNESS OR CONNECTOR
OK


3.INSPECT AFS ECU
