About B1552

B1552 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 B1552 is stored, the module has detected an open (broken or disconnected) electrical path 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.

B1552 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 electrical circuit that controls the decklid (trunk lid) release solenoid or actuator. DTC B1552 is set when the BCM detects an open circuit condition on the decklid release output, meaning current flow cannot be established when the output is commanded. This typically indicates a broken wire, a disconnected solenoid, an open solenoid winding, or a corroded connector that has lost continuity. When this code is active, the trunk will fail to release electrically through the interior switch, key fob, or smart entry system, and a warning may appear on th...
