DTC Descriptor
DTC B2615 00: Passenger Compartment Dimming 2 CircuitDiagnostic Fault Information
Circuit | Short to Ground | Open/High Resistance | Short to Voltage | Signal Performance |
|---|---|---|---|---|
BCM Supply Voltage | B2615 00 | B2615 00 | -- | -- |
Courtesy Lamp Control | B2615 00 | 1 | 1 | -- |
1. Courtesy Lamps Malfunction | ||||
Circuit/System Description
Battery voltage for the courtesy lamps is supplied at all times, from the BCM 3 fuse located in the underhood fuse block, to the body control module (BCM). When the BCM receives a signal to command the courtesy lamps ON, it applies voltage through the courtesy lamps supply voltage circuits to the courtesy lamps listed below.
| • | The left and right I/P courtesy lamps |
| • | Dome lamp |
Conditions for Running the DTC
| • | Ignition ON. |
| • | Courtesy lamps ON. |
Conditions for Setting the DTC
The BCM detects a short to ground on the courtesy lamp supply voltage circuit.
Action Taken When the DTC Sets
The BCM will deactivate the courtesy lamps.
Conditions for Clearing the DTC
| • | The condition responsible for setting the DTC no longer exists. |
| • | A history DTC will clear once 100 consecutive malfunction-free ignition cycles have occurred. |

Circuit/System Verification
Ignition ON, command the Courtesy Lamps ON and OFF with the scan tool. The interior courtesy lamps should turn ON and OFF when changing between commanded states.
Circuit/System Testing
- Ignition OFF, disconnect the X4 harness connector at the BCM.
- Ignition ON, verify that a test lamp illuminates between the B+ circuit terminal 2 and ground.
- Ignition OFF, connect the X4 harness connector at the BCM.
- Disconnect the harness connectors at all components fed by the courtesy lamp control circuit terminal 5 X2.
- Ignition ON, with a scan tool, clear the DTC.
- Operate the vehicle within the conditions for setting the DTC and verify that the DTC does not reset.
- Reconnect each component one at a time and verify the DTC does not reset.
| ⇒ | If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance. If the circuit tests normal, and the B+ circuit fuse is open, test the control circuit terminal 5 X2 for a short to ground. |
| ⇒ | If the DTC resets, test the control circuit for a short to ground. |
| ⇒ | If the DTC resets, replace the component responsible for setting the DTC. |
Repair Instructions
Perform the Diagnostic Repair Verification after completing the diagnostic procedure.

1. Courtesy Lamps Malfunction | ||||
Circuit/System Description
Battery voltage for the courtesy lamps is supplied at all times, from the BCM 3 Fuse located in the underhood fuse block, to the body control module (BCM). When the BCM receives a signal to command the courtesy lamps ON, it applies voltage through the courtesy lamps relay control circuit in order to energize the relay. With the relay energized, battery voltage is applied through switch side of the relay and the courtesy lamp supply voltage circuits to the courtesy lamps listed below.
| • | Front dome lamp |
| • | Rear dome lamp |
Conditions for Running the DTC
| • | Ignition ON. |
| • | Courtesy lamps ON. |
Conditions for Setting the DTC
The BCM detects a short to ground on the courtesy lamp PCB relay control circuit.
Action Taken When the DTC Sets
The BCM will deactivate the courtesy lamps.
Conditions for Clearing the DTC
| • | The condition responsible for setting the DTC no longer exists. |
| • | A history DTC will clear once 100 consecutive malfunction-free ignition cycles have occurred. |

Circuit/System Verification
Ignition ON, command the Courtesy Lamps ON and OFF with the scan tool. The interior courtesy lamps should turn ON and OFF when changing between commanded states.
Circuit/System Testing
- Ignition OFF, disconnect the X4 harness connector at the BCM.
- Verify that a test lamp illuminates between the B+ circuit terminal 2 and ground.
- Ignition OFF, connect the X4 harness connector at the BCM and disconnect the X1 harness connector at the underhood fuse block.
- Connect a test lamp between the control circuit terminal 20 and ground.
- Ignition ON, command the Courtesy Lamps ON and OFF with a scan tool. The test lamp should turn ON and OFF when changing between the commanded states.
- If all circuits test normal, replace the underhood fuse block.
| ⇒ | If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance. If the circuit tests normal, and the B+ circuit fuse is open, test the control circuit terminal 5 and the right front turn signal for a short to ground. If all circuits and component test normal, replace the BCM. |
| ⇒ | If the test lamp is always ON, test the control circuit for a short to voltage. If the circuit tests normal, replace the BCM. |
| ⇒ | If the test lamp is always OFF, test the control circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the BCM. |
