B1495: Decklid Punch-Out Sensor Circuit Fault
The B1495 code indicates that the Body Control Module (BCM) has detected a fault in the decklid punch-out sensor circuit. This sensor monitors the position or status of the emergency or power release mechanism for the trunk lid. The fault is triggered when the sensor signal is out of range, shorted to ground or battery, or the circuit is open.
1. Commonly Affected Makes
2. Most Common Causes
- Faulty decklid punch-out sensor
- Short, open, or corroded wiring or connectors in the sensor circuit

4. Step-by-Step Diagnosis
Scan for B1495 and any related codes
Inspect the decklid punch-out sensor and its wiring for damage, corrosion, or loose connections
Test sensor signal voltage and continuity per manufacturer specifications
Check mechanical operation of the decklid latch and release mechanism
If all else is good, test or replace the BCM
