B1497 — Decklid Punch-Out Sensor Battery Short

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

About B1497

B1497 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 B1497 is stored, the module has detected a short-circuit (voltage pulled to ground or to supply) 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.

B1497 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 at 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 B1497 sets specifically when the BCM detects the punch out sensor signal wire shorted to battery positive, presenting a constant high voltage on the input rather than the expected low current pull up reference behaviour. When this code is active the perimeter security system cannot in...
