SPEED SENSOR TESTER (SST)

Jaltest SST Speed Sensor Tester (SKU 50004002) — $345 The Jaltest SST (Speed Sensor Tester, part 50004002, $345) is a portable, compact device for verifying the correct operation of active and passive speed sensors on commercial trucks, construction equipment, and agricultural machinery. Per the official Cojali/Jaltest pricelist, it operates in two modes — testing the sensor itself and testing the ECU input it connects to — and uses an LED indicator panel to display results clearly. This tool substantially reduces the time spent on speed sensor fault diagnosis by giving technicians a definitive pass/fail result at the sensor level, without substituting parts or setting up an oscilloscope. Two Operating Modes Sensor test mode: Directly tests the speed sensor's output to confirm whether the sensor itself is generating a correct signal ECU test mode: Tests the ECU input to which the sensor is connected, to confirm whether the problem is in the ECU side of the circuit rather than t
