About B1488

B1488 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 B1488 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.

B1488 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

This code indicates the Body Control Module (BCM) or door control module has detected an open circuit on the right front door handle signal line. The handle assembly typically contains a switch or capacitive sensor that pulls the signal to a known state when the handle is operated, supporting keyless entry, passive entry, and door status detection. An open circuit means the module is no longer reading the expected voltage, current, or pull down behaviour from the handle, often because of a broken conductor, an unplugged connector, or a failed sensor element. When this code sets, the right fron...
