2004 BRAKES
Anti-Lock Braking System (ABS) - Endeavor
GENERAL DESCRIPTION FEATURES The 4ABS ensures directional stability and control during hard braking.
This ABS uses a 4-sensor 4-channel system that controls all four wheels
independently of each other. The basic system is the same as that for the Lancer.
EBD (Electronic Brake-force Distribution system) control has been installed to
provide the ideal braking force for the rear wheels.
EBD CONTROL In ABS, electronic control is used so the rear wheel brake hydraulic pressure during
braking is regulated by rear wheel control solenoid valves in accordance with the
vehicle's rate of deceleration. The front and rear wheel slippages are calculated from
the signals received from the various wheel sensors. EBD control is a control
system which provides a high level of control for both vehicle braking force and
vehicle stability. The system has the following features:
To shorten the harness wires and enhance data transmission reliability,
communication with other ECU is performed over a CAN (Controller Area
Network). Fail-safe function ensures that safety is maintained. Diagnostic function provides improved serviceability. Because the system provides the optimum rear wheel braking force regardless
of vehicle load and the condition of the road surface, the system reduces the
required pedal depression force, particularly when the vehicle is heavily
loaded. Because the duty placed on the front brakes is reduced, the increases in pad
temperature can be controlled during front brake application to improve pad
wear.

Harness (MB991970) to the wiring harness-side connector.
2. Turn the ignition switch to the "ON" position.
3. Measure the voltage between the relevant signal and ground terminals in
the ABS sensor circuit and body ground. It should be less than 1V.
