B1481 — Wiper Washer Fluid Level Sensor Circuit Short To Battery

System: Body  |  Type: Manufacturer-Specific  |  Make: Generic

About B1481

B1481 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 B1481 is stored, the module has detected a short-circuit (voltage pulled to ground or to supply) 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.

B1481 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 B1481 is set when the control module detects a short to battery voltage on the washer fluid level sensor circuit, meaning the signal wire is reading at or near 12V regardless of sensor state. This typically indicates a chafed signal wire contacting a power source somewhere in the loom, an internal sensor fault that has shorted to its supply, or a connector that has been forced together with a foreign object b...
