C1237 LEXUS Description
The Skid Control ECU measures the speed of each wheel by receiving signals from the speed sensor. These signals are used for recognizing that all four wheels are operating properly.

The Diagnostic Trouble Code (DTC) will set when the Skid Control ECU detects a discrepancy among four wheel speed sensor output or abnormal pulse signals from 3 or more sensors.
