B16DF (15) — Security Transmitter Sensor Circuit

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

About B16DF

B16DF is a manufacturer-specific body diagnostic trouble code recorded for Ram vehicles. It belongs to the B-prefix family of codes, which covers body, interior, airbag, or comfort-electronics faults.

When B16DF is stored, the module has detected 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.

B16DF 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 security transmitter sensor is part of the Ram vehicle theft and intrusion detection system, providing the Body Control Module (BCM) with a signal that confirms the integrity of the security transmitter circuit during self tests and during arm or disarm requests. DTC B16DF:15 indicates that the BCM has detected an open circuit condition in the transmitter sensor signal path, where the expected response from the sensor was not received during the monitoring routine. The fault is stored when the BCM commands or polls the security transmitter and the circuit fails to respond within the expect...
