what does code B1343 indicate for my Ford Explorer Fifth Generation (2011-2019)?

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the battery to ensure safety during repair.
• Ensure you have the vehicle’s service manual for wiring diagrams.

2. Inspect and Clean Battery Connections

• Sub-steps:
  • Remove the negative (-) battery terminal, followed by the positive (+) terminal.
  • Inspect the terminals for corrosion; clean them using a wire brush and a baking soda solution if necessary.
  • Reconnect the terminals, ensuring they are tight and secure.

3. Replace Faulty Fuse

• Sub-steps:
  • Locate the fuse box, typically found under the dashboard or in the engine compartment.
  • Use the vehicle's manual to identify the fuse related to the BCM.
  • Remove the fuse using a fuse puller and inspect it for continuity; replace it with the same amp rating if blown.

4. Test and Replace BCM (if necessary)

• Sub-steps:
  • If the BCM is found faulty during testing, disconnect the wiring harness from the BCM.
  • Remove any screws or bolts securing the BCM in place and carefully pull it out.
  • Install the new BCM by reversing the removal steps, ensuring all connectors are secure.
  • Reconnect the battery and clear any trouble codes using the OBD-II scanner.
