3. Push the sensor completely inside the
spring clip until it is in contact with the tooth
wheel. Ensure mounting is rigid, as it is an
important criterion for adequate sensor
operation.
NOTE
This installation should be of the "press fit"
type.
20.4.1 Spring clip
The spring clip retains the sensor in its
mounting bracket close to the toothed pulse
wheel. The gap between the sensor end and
teeth is set automatically by pushing the sensor
in the clip hard up against the tooth wheel, and
the latter knocks back the sensor to its adjusted
position (Figure 59).

Maintenance
The spring clip requires no specific
maintenance.
MAINTENANCE
ABS & ELECTRONIC STABILITY
CONTROL SYSTEMS
Check the proper functioning of ABS and
ESC systems at the intervals specified by the
Lubrication And Servicing Schedule in
Section 24A. To do so,
perform the
“Component Test” using Bendix ACom
Diagnostics software.
Bendix ACom Diagnostics software is
available for download at www.bendix.com.
21. BENDIX AUTOMATIC TRACTION
CONTROL (ATC) – ELECTRONIC STABILITY
CONTROL (ESC)
In addition to the ABS function, vehicle is
equipped with a Traction Control System (TCS)
feature. This feature is provided by the Bendix
ESP EC-80 controller. Bendix refers to this
feature as Automatic Traction Control (ATC).
Bendix ATC can improve vehicle traction during
acceleration, and lateral stability while
accelerating through curves. ATC utilizes
Engine Torque Limiting (ETL) where the ECU
communicates with the engine’s controller
and/or Differential Braking (DB) where
individual wheel brake applications are used to
improve vehicle traction.
The ESP EC-80 model controller also provides
an ABS-based Electronic Stability Control (ESC)
feature. Bendix refers to it as ESC Electronic
Stability Control.
The Bendix ESC system is an ABS-based
stability system that enhances vehicle stability
by both reducing engine throttle and by applying
vehicle braking based on actual vehicle
dynamics
ESC stability system consists of Yaw Control
(YC) and Roll Stability Program (RSP) features.
DANGER
Bendix ESC system may reduce the
vehicle speed automatically.
ESC can make the vehicle decelerate
automatically. ESC can slow the vehicle with
or without the operator applying the brake,
and
even when the throttle is being
applied.
CAUTION
Even with ESC-
equipped vehicles, the driver
remains responsib
le for ensuring vehicle
stability during operation.
