the headlamp switch, the headlamp delay module
powers the headlamps for approximately 45 seconds.
When the ignition switch is in the RUN position,
circuit A21 powers circuit F87 through fuse 17 in the
fuse block. Circuit F87 supplies the IGNITION ON/
OFF signal to the headlamp delay module. Circuit Z1
provides ground for the module.
When the headlamp delay module activates, it con-
nects circuit X4 from fuse 11 in the fuse block to cir-
cuit F34. Circuit F34 powers the headlamps through
the headlamp dimmer switch circuit L3.
HELPFUL INFORMATION
Circuit A7 from fuse 3 in the PDC supplies voltage

headlamps operate when the ignition switch is in the
RUN position.
When the ignition switch is in the RUN position,
circuit A1 from fuse 6 in the Power Distribution Cen-
ter (PDC), connects to circuit A21. Circuit A21 splices
to supply power to the DRL module.
Circuit A3 from fuse 5 in the PDC connects to DRL
module. Circuit A3 is HOT at all times.The DRL module receives the vehicle speed sensor
input from circuit G7. Circuit G465 from the DRL
module splices to circuit L3 to provide power for the
high beam indicator lamp in the instrument cluster.
Circuit L4 powers the low beams of the left and
right headlamps. When the headlamp switch is OFF,
the DRL module powers the low beams on circuit L4.
