About B1480

B1480 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 B1480 is stored, the module has detected an open (broken or disconnected) electrical path in the monitored circuit; and 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.

B1480 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 washer fluid level sensor is a float type or thermistor type sensor mounted in the washer reservoir, providing the BCM with a low fluid signal so the cluster can warn the driver. Code B1480 is set when the control module detects an open circuit in the sensor wiring, meaning the signal or return path has lost continuity. This typically happens when the sensor is unplugged, the harness has a broken conductor, or a connector terminal has corroded through. When this code is set the low washer fluid warning will usually remain off regardless of actual fluid level, or in some vehicles will stay ...
