DTC Descriptor
DTC B096A 02
- Hazard Lamps Switch Backlight Circuit Short to Ground
Diagnostic Fault Information
Circuit/System Description
The body control module (BCM) supplies a voltage reference through the instrument panel cluster dimming voltage reference circuit to the
instrument panel cluster lamps dimmer switch, which is part of the headlamp switch. When the dimmer switch is placed in a desired brightness
position, reference voltage is applied through the dimmer switch rheostat and the cluster lamps dimmer switch signal circuit to the BCM. The BCM
interprets this voltage signal, then applies a pulse width modulated (PWM) voltage to the LED dimming supply circuit to all related interior lamps,
illuminating them to the desired level of brightness.
Conditions for Running the DTC
The ignition is ON.
Conditions for Setting the DTC
B096A 02
The BCM detects a short to ground on the LED backlight lamp control circuit.
Action Taken When the DTC Sets
The BCM will not dim or illuminate any LED backlighting supplied by the backlight lamp control circuits.
Conditions for Clearing the DTC
* The condition responsible for setting the DTC no longer exists.
* A history DTC will clear once 100 consecutive malfunction ignition cycles have occurred.
