B1496 — Decklid Punch-Out Sensor Open Circuit

System: Body  |  Type: Manufacturer-Specific  |  Make: Ford

About B1496

B1496 is a manufacturer-specific body diagnostic trouble code recorded for Ford vehicles. It belongs to the B-prefix family of codes, which covers body, interior, airbag, or comfort-electronics faults.

When B1496 is stored, the module has detected an open (broken or disconnected) electrical path in the monitored circuit; and a sensor-related fault — the reported value from the named sensor is out of spec.

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.

B1496 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) monitors the decklid punch out sensor as part of the vehicle's perimeter security system. This sensor sits in the trunk lock cylinder assembly and is designed to detect tampering, specifically a forced entry attempt where the lock cylinder is physically pushed out of the decklid. DTC B1496 sets specifically when the BCM detects an open circuit in the sensor signal wiring, sensor return path, or the sensor element itself, meaning no current flow is possible through the circuit. When this code is active, the perimeter security system loses its ability to detect a pu...
