Case IH 2382-05 - BCM – BCM: Work lamp #5 - open circuit

The fault code indicates an open circuit in the circuit for Work Lamp #5. An open circuit means there is a physical break in the electrical path—such as a severed wire, a disconnected or loose harness connector, a blown fuse, or a burned-out bulb—preventing electrical current from completing the circuit to the lamp.

1. 1

   Connect a diagnostic tool (such as a DPA) and access the BCM configurations to see if the BCM automatically removed the affected light as an active option.

2. 2

   Disconnect the harness at the BCM and the work lamp, then check the resistance between the specific output pin for Work Lamp #5 and the ground pin to confirm the open circuit.

3. 3

   Inspect the connectors for enlarged contact springs on the female terminals by performing a terminal pin fitment test with a matching male terminal.

1. 1

   Isolate the Circuit

   Turn off the machine and disconnect the battery ground to prevent shorting.

2. 2

   Inspect the Bulb/Lamp

   Remove Work Lamp #5 and test it directly with a 12V power source or check it for continuity. If the lamp is burned out, replace the lamp assembly.

3. 3

   Inspect the Harness

   Trace the wiring harness from Work Lamp #5 back to the BCM. Look for chafed wires, pinched harnesses, or disconnected plugs.

4. 4

   Repair the Connector

   If the diagnostic pin-fitment test revealed a loose female terminal, de-pin the connector and replace the enlarged female terminal.

5. 5

   Clear and Reconfigure

   Reconnect all harnesses. Reconnect the battery. Connect the diagnostic tool to the BCM, clear the 2382-05 fault code, and ensure the work lamp is re-enabled in the BCM lighting configuration menu.
