B1607 is a manufacturer-specific body diagnostic trouble code. It is defined as "Illuminated Entry Input Circuit Failure". It falls under the body electronics area of the vehicle’s body system, and its exact meaning can vary between manufacturers.
The onboard diagnostic system sets B1607 when it detects a condition matching "illuminated entry input circuit failure" in the body electronics circuit or system. When the fault is confirmed, the module stores the code and, in most cases, turns on a warning light.
This code is generally considered serious. Continued driving may worsen the fault or affect safety and drivability. Have it diagnosed promptly.
B1607 means "Illuminated Entry Input Circuit Failure". It is a manufacturer-specific body trouble code in the body electronics area.
Because this code is often serious, it is best to limit driving and have the vehicle diagnosed as soon as possible. Continuing to drive may worsen the fault or affect safety.
There is no single fix. Start by confirming the code with a scan tool, then work through the likely causes and checks above — inspecting wiring, connectors and the relevant components before replacing any parts. On your specific make, confirm the diagnosis before repairs.
You can clear the code with an OBD-II scan tool, but if the underlying fault is still present it will usually return. Clearing without repair is only useful to confirm whether the fault is active.
