Is the resistance correct?

Same LEDs illuminated?

Ignition off. Remove connector from EC-14

™

 controller.

Measure resistance between the appropriate speed

signal pins on the connector. Resistance for Bendix

®

WS-20

™

 speed sensor is between 1500-2500 Ohms.

Refer to vehicle manual for the resistance values if

other than WS-20

™

 speed sensor is in use.

Go to Section IV “Inspection

for Illuminated LEDs”

YES

Disconnect connector at speed sensor.

Inspect the connector, then check the

resistance between two pins on sensor.

Is resistance between 1500-2500 Ohms for

the Bendix
