Case IH 2382-06 - BCM – BCM: Work lamp #5 - short circuit to ground

The electrical circuit supplying power to the number 5 work lamp has an unintended path to the machine's ground (chassis or ground wire). This condition typically causes the control module to disable the circuit to prevent wiring damage or blown fuses.

1. 1

   Consult the operator's manual to identify exactly which physical light on the cab corresponds to Work lamp #5 for your specific lighting package.

2. 2

   Disconnect the electrical connector directly at Work lamp #5 to isolate the component.

3. 3

   Use a multimeter to check for internal continuity between the power and ground pins on the lamp assembly itself. If there is continuity where there shouldn't be, the lamp is internally shorted.

4. 4

   With the lamp disconnected, use a multimeter to test the power supply wire on the machine-side harness for continuity to ground. If continuity to ground is present, the short is in the wiring harness between the BCM and the lamp connector.

5. 5

   Trace the wiring harness from the lamp back to the BCM, looking for pinched wires, chafed insulation rubbing against the cab frame, or melted connectors.

1. 1

   Power Down

   Turn off the tractor and disconnect the battery to ensure safety while working on the electrical system.

2. 2

   Address the Short

   If the wiring harness is damaged: Repair the chafed or broken wire by cutting out the damaged section, splicing in a new piece of wire, and sealing it with weather-resistant heat-shrink tubing. Secure the harness away from sharp edges using zip ties. If the work lamp is internally shorted: Unbolt the defective work lamp assembly from its mounting bracket and install a new replacement lamp.

3. 3

   Reassemble

   Reconnect the work lamp pigtail to the main harness.

4. 4

   Test

   Reconnect the battery and turn on the tractor's work lights to verify that Work lamp #5 illuminates and does not immediately trip the circuit.

5. 5

   Clear Codes

   Use the tractor's AFS Pro display or a dealer electronic service tool to clear the 2382-06 inactive fault code from the BCM memory.
