What is B1063?
DTC B1063 is a diagnostic trouble code that indicates a malfunction in the body control module's (BCM) communication with the vehicle's lighting system. This code is particularly common in vehicles like the 2015-2018 Toyota Camry and Honda Accord. When this code is triggered, it typically suggests that there's an issue with the vehicle's interior or exterior lighting, which can include everything from headlights and taillights to dashboard lights. If your vehicle's BCM is unable to properly communicate with these lighting components, it may lead to various problems, such as lights not functioning, flickering, or malfunctioning intermittently. Real-world implications of this issue can range from minor inconveniences, like not having proper cabin illumination, to more significant safety concerns, such as reduced visibility while driving at night. Ignoring this code can lead to further electrical issues within the vehicle, potentially escalating repair costs over time. It's essential to diagnose the specific components at fault to ensure safe and reliable vehicle operation.
System: B - Body (Airbags, Lighting, Security, Climate Control)
Symptoms
Common symptoms when B1063 is present:
- Check engine light or warning light on the dashboard stays illuminated constantly, indicating an unresolved issue.
- Interior lights may flicker or fail to operate, making it difficult to see inside the vehicle during nighttime.
- Exterior lights, such as headlights or brake lights, may not function properly, which can compromise safety while driving.
- Dashboard lights may dim unexpectedly or fail to illuminate, affecting visibility of critical driving information.
- Unexpected electrical malfunctions may occur, such as power windows or locks not responding when activated.
Possible Causes
Most common causes of B1063 (ordered by frequency):
- The most common cause of B1063 is a faulty body control module, with a likelihood of around 60%. This can occur due to water intrusion or circuit damage.
- A second common cause is damaged wiring or connectors in the lighting circuit, which can lead to intermittent or complete failures in lighting functions.
- Another cause could be a blown fuse associated with the BCM or lighting system; regularly checking and replacing fuses can help prevent this issue.
- Less common but serious causes include software issues within the BCM, which may require a firmware update or replacement of the module.
- A rare cause could be a short circuit in the vehicle's electrical system, necessitating a thorough inspection of all wiring harnesses.
