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.

3. Check that the basic ignition timing is within the standard value.
Standard value: 5° BTDC+/-3°
4. Start the engine and increase the engine speed to 2,500 r/min for 2 minutes.
5. Set the CO, HC tester.
6. Check the CO contents and the HC contents at idle.
Standard value:
CO contents: 0.5% or less
HC contents: 100 ppm or less
7. If the CO and HC contents do not remain inside the standard value, check the
following items:
Diagnostic output Closed-loop control (When the closed-loop control is carried out normally, the
output signal of the heated oxygen sensor changes between 0 - 400 mV and
600 - 1,000 mV at idle.) Fuel pressures Injector Ignition coil, spark plug EGR system and EGR valve leak Evaporative emission system Compression pressure

malfunction is a worn or damaged piston ring and/or cylinder inner
surface.
2. If the compression does not rise after oil is added, the cause is a burnt or
defective valve seat, or pressure is leaking from the gasket.
9. Connect the crankshaft position sensor connector.
10. Install the spark plugs and ignition coils.
11. Use the scan tool MB991958 to erase the diagnostic trouble codes.
NOTE: This will erase the diagnostic trouble code resulting from
the crankshaft position sensor connector being
disconnected.

When metering R-134a into the refrigeration system, keep the supply tank or cans
in an upright position. If the refrigerant container is on its side or upside down,
liquid refrigerant will enter the system and damage the compressor.
Refrigerant will tarnish bright metal and chrome surfaces, and in combination with
moisture can severely corrode all metal surfaces. OPERATION CONDENSER FAN AND RADIATOR FAN CONTROL For the operation of each fan, refer to
SYMPTOM CHART
.
COMPRESSOR CONTROL WHEN OPERATING THE AIR CONDITIONING SWITCH
The air thermo sensor, which senses the temperature of the air flowing out of
the evaporator, deactivates the compressor at 3°C (37.4°F) or below. The dual pressure switch turns OFF when the refrigerant pressure becomes
excessively high or low, thus protecting the compressor circuit. When the air thermo sensor is activated, and the ignition switch, blower switch,
and air conditioning switch are ON, the A/C compressor clutch relay is
energized.
WHEN OPERATING THE MODE SELECTION DIAL
The air conditioning will work when the mode selection dial is set to the
"Defroster" or "Defroster/foot" position, or the temperature control dial is set to
the "MAX A/C" position. In other dial positions, when the air conditioning
switch is turned on, the air conditioning will work.
