About B1489

B1489 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 B1489 is stored, the module has detected a short-circuit (voltage pulled to ground or to supply) 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.

B1489 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 a short to battery voltage on the right front door handle signal line. The handle assembly typically contains a switch or capacitive sensor whose signal swings between a defined low and high state, supporting keyless entry, passive entry, and door status detection. A short to battery pulls the signal permanently high, so the module sees a value well above the upper threshold and reports a circuit short. When this code sets, the right front handle may register as continuously activated, the door may fail to un...
