Works on ALL Wheel Speed Sensors. Identifies sensor shorts and opens. Visually verify sensor signal output. Signal Simulation enables easy harness testing. The ABS Sensor Pinpoint Tester is the quickest way to verify proper wheel speed sensor operation. Simply connect the tester to the sensor and spin the wheel. The parade of LEDs provide visual conﬁrmation of signal output. The signal error LED indicates erratic or intermittent signal output. When used with a scan tool that provides wheel speed sensor data, the Signal simulation feature simpliﬁes pinpointing wire harness problems. The quickest most comprehensive Wheel Speed Sensor diagnostic tester available! Kit Contents: Main unit, 14 Male/Female Flex Probe Adapters, 2 Alligator Clip Flex Probes and Test lead set (3 leads).
