Daytime Running Lamp: Description and Operation
DAYTIME RUNNING LAMPS (DRL) - DOMESTIC/CANADIAN
The daytime running lamps (DRL) will illuminate the right and left front turn signal bulbs continuously. The DRLs will operate when the following
conditions are met:
1. Ignition is in the RUN or CRANK position
2. Shift lever is out of the PARK position for vehicles equipped with automatic transmissions or the parking brake is released for vehicles with
manual transmissions.
3. High and low beam headlamps are OFF.
When conditions for DRL operation exist, the powertrain control module (PCM) sends a class 2 message to the dash integration module (DIM),
indicating the transmission is out of the PARK position. The DIM sends a signal to the turn signal/hazard flasher module by grounding the DRL signal
circuit of the turn signal/hazard flasher module. When the turn signal/hazard flasher module receives this signal the module supplies continuous
battery voltage to the right and left front turn signal lamps. The turn signal lamps are permanently ground at G104 and therefore illuminate. Turn
signal and hazard flasher operation take precedence over DRL operation. For Domestic vehicle only, DRL operation will be disabled if the Photocell
Status indicates Dark conditions, the twilight switch status OFF and either the front fog lamps or park lamps are turned ON.
DAYTIME RUNNING LAMPS (DRL) - NORWAY/SWEDEN
The daytime running lamps (DRL) will illuminate the low beam headlamps and the park lamps at normal intensity. The DRLs will operate when the
following conditions are met:
-
Ignition is in the RUN or CRANK position.
-
Shift lever is out of the PARK position for vehicles equipped with automatic transmissions or the parking brake is released for vehicles with
manual transmissions.
-
High and low beam headlamps are OFF.
-
Park lamps are OFF.
-
Fog lamps are OFF.
When conditions for DRL operation exist, the powertrain control module (PCM) sends a class 2 message to the dash integration module (DIM),
indicating the transmission is out of the PARK position. The DIM will then ground the control circuit of the DRL relay and the park lamp relay.
Battery voltage is supplied to the coil and switch side feed circuits of the DRL relay. When the DIM grounds the control circuit of the DRL relay the
switch contacts close and battery voltage is supplied to the low beam headlamps. Operation of the park lamps and are the same as described in the
park lamp section.
