B1482 — Wiper Washer Fluid Level Sensor Circuit Short To Ground

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

About B1482

B1482 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 B1482 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.

B1482 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 B1482 is set when the control module detects that the sensor signal circuit is shorted to ground, meaning the input pin is reading at or near 0V regardless of sensor state. The BCM applies a pull up reference to the signal line and watches for the float driven change in voltage; when the line is held at ground externally, the module flags a circuit fault. When this code is active the low washer fluid warning ...
