SIR/Cruise/Turn Coil Assembly

Check resistance through the coil assembly by measuring voltage at horn switch and rotating steering wheel.

Check for OPENS/SHORTS in cavities A, column side, and cavity 3, steering wheel side. Repair as needed.

Horn Switch

Check resistance through horn switch. The switch resistance should be less than one ohm when the horn pad is depressed and open when the horn pad is not depressed.

Check for OPENS/SHORTS.

Repair as needed.

Horn

Check resistance through the horn. Horn resistance should be 2-4 ohms.

Replace as needed.
