DTC Descriptor
DTC B2610 00 Passenger Compartment Dimming 1 Circuit

Diagnostic Fault Information






Circuit/System Description
When the interior lamps dimming switch is activated, a variable voltage signal is applied through the instrument panel lamps dimmer switch signal circuit to the body control module (BCM). The BCM then applies a variable voltage signal through the LED backlighting dimming supply circuit to the following components:
^ Clock
^ Diver Information center (DIC) switch
^ Headlamp Switch
^ HVAC Control Head
^ Rear HVAC Control
^ Radio
^ Rear Radio Entertainment
^ Steering Wheel Control Switch

Conditions for Running the DTC
The ignition is ON.

Conditions for Setting the DTC
The BCM receives a ground signal on the LED dimming supply circuit

Action Taken When the DTC Sets
The BCM cease attempt to dim or illuminate the LED lamps.

Conditions for Clearing the DTC
The BCM clears this code from current when the fault is removed from the system.

Circuit/System Verification
Ignition ON, cover the ambient light sensor, vary the interior lamp dimming switch from dim to full bright. The LED lamps should dim and then become full bright.

Circuit/System Testing
1. Disconnect all the LED backlighting dimming supply circuit lamps related components. Refer to the circuit/system verification for all components that contain the LED backlighting dimming supply circuit lamps. Verify the DTC B2610 does not set
^ If the DTC resets then test for a short to ground in the LED dimming supply circuit lamps circuit. If the circuit/connections test normal replace the BCM.

2. Reconnect each component one at a time and test for the DTC B2610. If the DTC resets then replace that component.
