B1513 — Driver Door Handle Circuit Short To Battery

About B1513

B1513 is a manufacturer-specific body diagnostic trouble code. It belongs to the B-prefix family of codes, which covers body, interior, airbag, or comfort-electronics faults.

When B1513 is stored, the module has detected a short-circuit (voltage pulled to ground or to supply) in the monitored circuit.

Scanning & clearing: Body (B) codes are often stored in the body control module, airbag module, or climate module. A basic OBD-II tool usually will not read body codes — an enhanced or OEM-level scan tool is typically required.

B1513 is a manufacturer-specific code. The same code string on a different make may have a different meaning. Always confirm the code's definition against the vehicle's service information for the specific make and model under test.

Code Information

The Body Control Module (BCM) or smart entry control module monitors the driver door handle circuit voltage to detect electrical faults that could affect passive entry operation or central locking function. DTC B1513 specifically sets when the module detects an unexpected battery voltage on a circuit that should normally sit at a low logic level or reference voltage, indicating a short to battery (B+) somewhere in the wiring or at the handle assembly. This often results from chafed insulation contacting an adjacent power wire, water bridging in the door cavity, or an internally shorted handle ...
