Neon L4-2.0L SOHC (1995)
Daytime Running Lamp Control Unit: Description and Operation
DAYTIME RUNNING LAMP (DRL) MODULE - CANADIAN VEHICLES ONLY
On vehicles built for sale in Canada, the low-beam headlamps operate when the ignition switch is in the RUN position, and the parking brake
switch is open.
In the Power Distribution Center (PDC), a bus bar connected to battery voltage feeds circuit A1. In the RUN position, the ignition switch connects
circuit A1 to circuit A21. A 30 amp maxi fuse in the PDC, protects circuits A1 and A21.
Circuit A21 connects to a bus bar in the fuse block that feeds circuit G5 through a 5 amp fuse in cavity 11. Circuit G5 is powered only when the
ignition switch is in the RUN position. Circuit G5 connects to cavity 1 of the DRL module.
Circuit G9 connects to cavity 3 of the DRL module. The G9 circuit splices to the brake warning switch, park brake switch, and instrument cluster
brake warning bulb.
Circuit L20 from the headlamp and dimmer switch supplies battery voltage to the DRL module at all times. Circuit A3 from the Power
Distribution Center feeds circuit L20. Circuit L20 connects to cavity 6 of the DRL module connector. A 40 amp maxi fuse in the PDC protects the
From the DRL module, circuit L4 powers the lowbeams of the left and right headlamps. The DRL controls the power to circuit L4. Circuit L4
connects to cavity 10 of the DRL module.
Circuit L3 feeds the high beams of the headlamps. When the operator flashes the headlamps with the stalk of the multi-function switch, the DRL
senses voltage on circuit L3. When it senses voltage on circuit L3, the DRL module stops supplying power to the low beams on circuit L4.
Circuit L4 originates at cavity 4 of the multi-function switch. The L4 circuit splices to cavity 10 of the DRL module.
