When a Chevrolet B1370 01 Code is detected, this indicates that the ignition switch is either in the off or ACC positions. This code is associated with several potential causes and solutions, ranging from open or shorted circuits to a faulty ignition switch. The B1370 01 Code can also be caused by a short to ground on the accessory voltage, run/crank ignition 1 voltage BCM terminal 19, X4, off/run/crank voltage or the B+ circuit. Additionally, if an open is detected on the B+ circuit when the engine is running, this can be a sign of a general electrical failure.
Common Causes and Solutions of the Chevrolet B1370 01 Code
| Cause | Solution |
|---|---|
| Ignition 1 voltage circuit is shorted to voltage. | Replace the ignition switch. |
| B+ circuit of the ignition switch open or shorted to ground. | Inspect wiring and repair as necessary. |
| Accessory voltage circuit is shorted to voltage. | Check the connection to the ignition switch. |
| BCM senses an open or short to voltage on the off/run/crank voltage circuit. | Inspect for loose connections and repair as necessary. |
Chevrolet B1370 01 Code is a diagnostic trouble code indicating that the ignition switch is in the off or ACC positions. This code is often associated with several potential causes and solutions, such as open or shorted circuits, faulty ignition switch, short to ground on the accessory voltage, run/crank ignition 1 voltage BCM terminal 19, X4, off/run/crank voltage, and B+ circuit. If a Chevrolet vehicle is experiencing a general electrical failure, it is important to take the necessary steps to identify and troubleshoot the issue. This may include inspecting wiring and repairing any loose connections. Additionally, the ignition switch may need to be replaced if it is determined to be the source of the problem.
Open or Shorted Circuits
One of the most common causes of the Chevrolet B1370 01 Code is an open or shorted circuit. This can occur if the ignition switch is not functioning properly and is not able to send the correct electrical signals. If the ignition switch is the source of the issue, then it is important to replace it with a new component. Alternatively, the wiring connection to the ignition switch may need to be checked and repaired as necessary.
Short to Ground on the Accessory Voltage
The Chevrolet B1370 01 Code can also be caused by a short to ground on the accessory voltage, run/crank ignition 1 voltage BCM terminal 19, X4, off/run/crank voltage, or the B+ circuit. If a short to ground is detected on the B+ circuit, it is important to inspect the wiring and repair any loose connections that may be present. Additionally, any open or shorted circuits should be identified and repaired as necessary.
Conclusion
When a Chevrolet B1370 01 Code is detected, it is important to take the necessary steps to identify and troubleshoot the issue. Common causes of this code include open or shorted circuits, faulty ignition switch, short to ground on the accessory voltage, run/crank ignition 1 voltage BCM terminal 19, X4, off/run/crank voltage, and B+ circuit. To resolve these issues, it may be necessary to replace the ignition switch, check and repair any wiring connections, and inspect for loose connections. By taking the appropriate steps, the Chevrolet B1370 01 Code can be resolved and the vehicle can be back on the road in no time.
