Solution

1. Preparation

  • Gather tools and parts required for the repair.
  • Disconnect the negative battery terminal to prevent electrical shock.
  • Ensure the vehicle is on a flat surface and the ignition is off.

2. Inspect and Repair Wiring

  • Sub-step 1: Visually inspect the wiring harness for any signs of fraying, cuts, or corrosion.
  • Sub-step 2: Repair any damaged wires using appropriate electrical tape or heat-shrink tubing.
  • Sub-step 3: Clean any corroded connectors using electrical contact cleaner and a brush.

3. Replace Fuses

  • Sub-step 1: Locate the fuse box and identify the fuses related to the BCM.
  • Sub-step 2: Remove any blown fuses and replace them with new fuses of the same amperage.
  • Sub-step 3: Ensure the fuse clips are clean and secure to maintain proper contact.

4. Test the BCM

  • Sub-step 1: Reconnect the battery and turn the ignition on without starting the engine.
  • Sub-step 2: Use the OBD-II scanner to check for new codes or confirmation that the B1000 code is no longer present.
  • Sub-step 3: Verify that all electrical components controlled by the BCM are functioning correctly.

5. Replace BCM (if necessary)

  • Sub-step 1: If the code persists, remove the BCM by unscrewing it from the mounting location.
