shorted to ground inside steering
wheel.
(2) Pinched horn switch wire under
Driver Airbag Module
(3) Defective horn switch
(1) Check fuse 23 in PDC
(2) No Voltage at horn RELAY
TERMINALS 62 & 66, and fuse is
OK.
(3) Open circuit from terminal 65 of
the horn relay to horn switch X3
circuit.
(4) Defective or damaged horn.
(5) Defective horn switch
