what does the code B1000 mean for my Toyota Camry Seventh Generation (2012-2017)?

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the negative battery terminal to ensure safety while working on the airbag system.

2. Inspect and Repair Wiring

• Remove the necessary interior panels to access the airbag module wiring.
• Inspect all wires for damage and repair any frayed or broken wires using heat-shrink tubing or electrical tape.
• Ensure all connectors are secure and free from corrosion.

3. Check and Replace Components

• If the seat occupancy sensor is faulty, replace it with a new unit.
  • Remove the seat cushion or cover to access the sensor.
  • Disconnect the sensor wiring harness.
  • Install the new sensor and reconnect the wiring harness.
• If the body control module is suspected to be faulty, replace it:
  • Locate the BCM and disconnect all wiring harnesses.
  • Remove the mounting screws and take out the BCM.
  • Install the new BCM by reversing the removal steps.

4. Reconnect and Test

• Reconnect the negative battery terminal.
• Clear any stored trouble codes using the diagnostic scanner.
• Start the vehicle and monitor for any warning lights.
