INSPECTION PROCEDURE

PROCEDURE

1. CHECK DTC (BRAKE CONTROL SYSTEM)

(a) Check that the steering sensor DTC (brake control system DTC) is not output.

Result:





B -- REPAIR CIRCUITS INDICATED BY OUTPUT DTCS (BRAKE CONTROL SYSTEM)
A -- Continue to next step.

2. READ VALUE USING TECHSTREAM

(a) Connect the Techstream to the DLC3.

(b) Turn the engine switch on (IG).

(c) Turn the Techstream on.

(d) Enter the following menus: Body Electrical / AFS / Data List.

(e) Read the display on the Techstream.

AFS (AFS ECU)

AFS (AFS ECU):

OK:

Condition sign can be displayed.

Result:





C -- CHECK HARNESS AND CONNECTOR (STEERING ANGLE SENSOR - AFS ECU)

B -- REPLACE AFS ECU

A -- PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN PROBLEM SYMPTOMS TABLE

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

(a) Disconnect the J23 steering angle sensor connector.





(b) Disconnect the A27 AFS ECU connector.

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

Standard resistance:





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

4. CHECK AFS ECU

(a) Reconnect the A27 AFS ECU connector.





(b) Measure the voltage according to the value(s) in the table below.

Standard voltage:





OK -- REPLACE STEERING ANGLE SENSOR

NG -- REPLACE AFS ECU
