B1247 2016 Toyota RAV4 Code - Tire Pressure Monitor Receiver Communication Stop

The code B1247 indicates a communication stop between the tire pressure monitor receiver and the main vehicle system.

Common symptoms include the tire pressure monitoring system (TPMS) warning light staying illuminated on the dashboard and a loss of communication with the tire pressure sensors.

Potential causes of B1247 can include a faulty tire pressure monitor receiver, damaged wiring or connectors in the TPMS circuit, or a malfunction in the tire pressure sensors.

To diagnose the problem, you can use an OBDII scanner to retrieve the specific error codes, inspect the TPMS wiring and connectors for damage, and test the tire pressure sensors for proper functionality.

It is not recommended to continue driving with the TPMS warning light illuminated, as this can compromise your ability to monitor tire pressure accurately, leading to potential safety risks.

After resolving the problem causing code B1247, you can reset the TPMS system by following the specific procedure outlined in your vehicle's owner's manual or using a TPMS reset tool.

While diagnosing and repairing electrical issues can be challenging, checking for loose connections, damaged wires, and ensuring proper sensor placement can sometimes resolve the B1247 code.

The cost of repairing B1247 can vary depending on the root cause of the issue. It may range from a simple fix like reconnecting wires to replacing the tire pressure monitor receiver, which can be more expensive.

Extreme temperatures or weather conditions can potentially impact the tire pressure sensors or TPMS components, leading to communication errors like code B1247. Regular maintenance and monitoring can help prevent such issues.

While dealership technicians are trained to work on specific vehicle models like the RAV4, independent repair shops with experience in handling TPMS issues can also effectively diagnose and repair code B1247.
