Daytime Running Lamp: Pinpoint Tests
PINPOINT TEST AE: THE DAYTIME RUNNING LAMPS (DRL) ARE INOPERATIVE
Normal Operation
When the ignition switch is in the RUN position, the headlamps are not on (from the autolamp system or manual control from the headlamp switch)
and the transmission is not in PARK (P), the smart junction box (SJB) provides a pulse-width modulated (PWM) voltage to the low beam headlamps.
This illuminates the headlamps at a reduced intensity.
This pinpoint test is intended to diagnose the following:
-
Exterior lighting system input/output
-
Ignition switch input
-
Transmission gear input
-
SJB
