Bendix Commercial Vehicle Systems is reinforcing the importance of following proper installation and service
guidelines for installing, routing and securing wheel speed sensors, sensor cables and wire harnesses for Bendix
Antilock Braking Systems (ABS).

Bendix has discovered that if wheel speed sensor cables are not properly routed and secured, the cable could rub
on rotating components, causing damage which, in rare circumstances, could result in a temporary exhaust of
brakes for a few seconds at low speeds.  Although this issue has only been reported on a small number of straight
trucks and buses, Bendix recommends that when servicing ABS, you ensure proper routing and securing of wheel
speed sensor cables.

Wheel Speed Sensor Cables
Wheel speed sensor cables coming directly out of the wheel ends should be routed at least 1.5 inches away from
moving components at all points and be properly secured to air lines and the axle to prevent excess cable slack
and potential chafing damage.  Ensure that the wheel speed sensor cables attached along the length of the service
brake hoses are secured with tie wraps at intervals of approximately six (6) inches and are securely connected to
the wiring harness.  In addition the wheel speed sensor cable should be secured with a tie wrap three (3) inches
from the sensor.
