(c) Turn the Techstream on.

(d) Enter the following menus: Body Electrical / AFS / Active Test.

(e) Check that the swivel motors operate.

AFS (AFS ECU)





OK:

Swivel motors operate.

Result:





C -- INSPECT HEADLIGHT ASSEMBLY

B -- REPLACE AFS ECU Components

A -- PROCEED TO NEXT SUSPECTED AREA SHOWN IN PROBLEM SYMPTOMS TABLE Exterior Lighting System

1. INSPECT HEADLIGHT ASSEMBLY





(a) Disconnect the B12 and B2 headlight connectors.

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

Standard Resistance:

LH Side (B2412)





RH Side (B2413)
