Laymans terms

The car's computer detected that the voltage from a sensor in the battery system is higher than it should be.

Explanation

The Battery Energy Control Module monitors the voltage levels of the battery. If the voltage reading from Sensor 'B' is too high, it triggers this code.

Technical description

This code indicates that the Battery Energy Control Module (BECM) has detected that the voltage from the voltage sensor 'B' in circuit 'B' is higher than the expected range. This could be due to a fault in the sensor, wiring issues, or a problem with the BECM itself.

Symptoms

• Check Engine Light is on

• Possible battery charging issues

• Reduced vehicle performance

Common Causes

• Faulty voltage sensor

• Wiring issues or poor connections

• Battery Energy Control Module malfunction

Glossary

Battery Energy Control Module: A component that manages the battery's energy and monitors its status.

Voltage Sensor: A device that measures the voltage level in a circuit.

Diagnosis steps

• Use an OBD-II scanner to confirm the code.

• Inspect the wiring and connections to Sensor 'B'.

• Test the voltage sensor for proper operation.

Repair procedures

• Replace the faulty voltage sensor.

• Repair or replace damaged wiring or connectors.

• Replace the Battery Energy Control Module if necessary.

Tools required

• OBD-II scanner

• Multimeter

• Basic hand tools

Estimated repair cost

$150 - $500
