About B3110

B3110 is a manufacturer-specific body diagnostic trouble code recorded for Holden vehicles. It belongs to the B-prefix family of codes, which covers body, interior, airbag, or comfort-electronics faults.

B3110 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.

Tracking each remote separately lets the system tell the driver which specific key needs attention. When this code is set the second remote may operate only at short range or intermittently, may eventually fail to lock or unlock the vehicle, and a low k...
