7-48 E –+ELECINDICATION SYSTEM Speedometer display 1. Check: Speedometer display Does not display → Measure the speed sensor output voltage and pulses. Without specification → Replace the multifunction meter. 2. Measure: Speed sensor output voltage and pulses Out of specification → Repair or replace. Speed sensor output voltage (dependant on the paddle wheel position): Less than 400 mV/ More than 11.6 V Output pulse: 2 pulses/one-full turn Measurement steps: Apply DC 12 voltage to the white color three-pin connector (between the red/yel- low and black/yellow leads). Rotate the paddle wheel by hand and measure the voltage between the black and yellow leads. NOTE: As the paddle wheel is rotated, a square- wave voltage signal a is produced. Two pulses occur every time the paddle wheel makes one-full turn.
