Diagnostic Fault Information
Circuit/System Description
When the headlight switch is placed in low beam position, the body control module (BCM) applies a voltage to the low beam headlamps through
their respective voltage supply circuits.
Conditions for Running the DTC
The headlamps are turned ON.
Conditions for Setting the DTC
B2575 01
The BCM detects a short to voltage on the left headlamp low beam control circuit.
B2575 02
The BCM detects a short to ground on the left headlamp low beam control circuit.
B2575 04
The BCM detects an open on the left headlamp low beam control circuit or an open/high resistance on the left headlamp low beam ground circuit.
B2699 01
The BCM detects a short to voltage on the right headlamp low beam control circuit.
B2699 02
The BCM detects a short to ground on the right headlamp low beam control circuit.
B2699 04
The BCM detects an open on the right headlamp low beam control circuit or an open/high resistance on the right headlamp low beam ground
circuit.
Action Taken When the DTC Sets
For B2575 02, B2575 04, B2699 02 or B2699 04, the appropriate headlamp low beam will be inoperative.
For B2575 01 or B2699 01, the appropriate headlamp low beam will be continuously illuminated.
