PRECAUTIONS FOR DIAGNOSIS
lBefore performing diagnosis, always read precautions. Refer toBRC-17, "CONSULT- II Functions".
lAfter diagnosis is finished, be sure to erase memory. Refer toBRC-18, "ERASE MEMORY".
lWhen checking continuity and voltage between units, be sure to check for disconnection, looseness,
bend, or collapse of connector terminals. If any malfunction is found, repair or replace connector termi-
nals.
lFor intermittent symptoms, possible cause is malfunction in harness, harness connector, or terminals.
Move harness, harness connector, and terminals to check for poor connections.
lIf a circuit tester is used for check, be careful not to forcibly extend any connector terminal.
lABS system electrically controls brake operation and engine output. Following symptoms may be caused
by normal operations:
Basic InspectionEFS005TY
BASIC INSPECTION 1 BRAKE FLUID LEVEL, LEAKS, AND BRAKE PADS
1. Check fluid level in the brake reservoir tank. If fluid level is low, refill brake fluid.
2. Check brake tube and around ABS actuator and electric unit (control unit) for leaks. If leakage or seepage
is found, check the following items.
lIf ABS actuator and electric unit (control unit) connection is loose, tighten brake tube to the specified
torque and re-conduct the leak inspection to make sure there are no leakage.
lIf there is damage to the connection flare nut or ABS actuator and electric unit (control unit) screw,
replace the damaged part and re-conduct the leak inspection to make sure there are no leakage.
lIf there is leakage or seepage at any location other than ABS actuator and electric unit (control unit)
connection, wipe away leakage or seepage with clean cloth. Then inspect again and confirm than there
is on leakage.
lIf there is leakage from ABS actuator and electric unit (control unit), wipe away leakage or seepage with
clean cloth. Then inspect again. If there is leakage or seepage, replace ABS actuator and electric unit
(control unit).
CAUTION:
ABS actuator and electric unit (control unit) body cannot be disassembled.
3. Check brake pad degree of wear. Refer toBR-24, "
PAD WEAR INSPECTION"in “Front Disc Brake” and
BR-32, "
Lining Thickness Inspection"in “Rear Drum Brake”.
BASIC INSPECTION 2 POWER SYSTEM TERMINAL LOOSENESS AND BATTERY INSPECTION
Make sure battery positive cable, negative cable and ground connection are not loose. In addition, check the
battery voltage to make sure it has not dropped and alternator is normal.
Symptom Symptom description Result
Motor operation noiseThis is noise of motor inside ABS actuator and electric unit (control unit). Slight
noise may occur during ABS operation.
Normal
Just after engine starts, motor operating noise may be heard. This is a normal
status of the system operation check.
System operation check noiseWhen engine starts, slight “click” noise may be heard from engine compart-
ment. This is normal and is part of system operation check.Normal
ABS operation
(Longer stopping distance)When driving on roads with a low coefficient of friction, such as snowy roads
or gravel roads, the stopping distance is sometimes longer for vehicles
equipped with ABS. Therefore, when driving on such roads, drive at a suffi-
ciently reduced speed to be safe.Normal

Fuel FilterEBS01KCK
DESCRIPTION
A water draining cock is on the lower side and a priming pump for bleeding air is on the upper side.
AIR BLEEDING
Pump the priming pump (1) to bleed air.
lWhen air is bled completely, the pumping of the priming pump
suddenly becomes heavy. Stop the operation at that time.
lIf it is difficult to bleed air by the pumping of the priming pump
(the pumping of the priming pump does not become heavy), dis-
connect the fuel supply hose between the fuel filter and the fuel
gallery. Then, perform the operation described above, and make
sure that fuel comes out. (Use a pan, etc. so as not to spill fuel.
Do not let fuel get on engine and other parts.) After that, connect
the hose, then bleed air again.
lStart engine and let it idle for at least 1 minute after performing
air bleeding.
WATER DRAINING
1. Remove the fuel filter, filter bracket, protector assembly from the dash panel as follows.
a. Remove the air cleaner case (upper), air duct assembly, and vacuum hose for brake booster (between the
vacuum pump and vacuum pipe).
CAUTION:
After the duct is removed, cover the opening with gum tape, etc. to prevent foreign object from
getting into the engine during the operation.
b. Remove the mounting nuts on the dash panel, then remove the fuel filter, filter bracket, and protector
assembly from the dash panel.
lIt is not necessary to disconnect the fuel hose.
2. Using a tool such as a pliers, loosen the water draining cock at
the bottom of the fuel filter.
Loosening drain cock four to five turns causes water to
start draining.
Do not remove drain cock by loosening it excessively.
If water dose not drain properly, move the priming up and down.
CAUTION:
When the water is drained, the fuel is also drained. Use a
pan, etc. to avoid fuel adherence to the rubber parts such as
the engine mount insulator.
Do not over-tighten the water draining cock. This will dam-
age the cock thread, resulting in water or fuel leak.
3. Bleed air of the fuel filter. Refer toEC-23, "
AIR BLEEDING".
4. Start the engine.

Injector Adjustment Value RegistrationEBS01KCM
DESCRIPTION
Injector adjustment value indicates manufacturing tolerance and the value is printed on the top of fuel injec-
tor.The injector adjustment value which is correctly stored in ECM is needed for precise fuel injection control.
A performance of emission control and a drivability may effect when there is a mismatch between the following
two values.
lThe injector adjustment value stored in ECM
lThe injector adjustment value of the injector which is installed on the vehicle
Injector Adjustment Value Registration must be performed after the following cases.
lInjector(s) are replaced.
lECM is replaced.
For the first case, Injector Adjustment Value Registration for the replaced fuel injector must be performed. And
for the second case, Injector Adjustment Value Registration for all the fuel injectors must be performed.
OPERATION PROCEDURE
NOTE:
lBefore performing this procedure, record injector adjustment value printed on a fuel injector.
lWhen all fuel injectors are replaced or ECM is replaced, it is recommended to perform “INJ ADJ
VAL CLR” in “WORK SUPPORT” mode before performing this procedure. By performing “INJ ADJ
VAL CLR” in “WORK SUPPORT” mode, injector adjustment value stored in ECM is initialized.
1. Turn ignition switch ON (engine stopped).
2. Select “ENTER INJECTOR CALIB DATA” in “WORK SUPPORT” mode with CONSULT-II.
3. Touch “START”.
NOTE:
When touching “START”, CONSULT-II reads injector adjustment values stored in ECM.
4. Select the number of the cylinder which needs Injector Adjustment Value Registration.
5. Input injector adjustment value, and touch “ENTER”.
NOTE:
Input injector adjustment value is stored in CONSULT-II.
6. Repeat step 4 - 5 till there is no cylinder which needs Injector Adjustment Value Registration, and touch
“START”.
NOTE:
When touching “START”, injector adjustment values stored in CONSULT-II are written onto ECM memory.
7. After “CMND FINISHED” is displayed, make sure that the following values are same for each cylinder.
lInjector adjustment value which is printed on a fuel injector.
lInjector adjustment value which is displayed on CONSULT-II screen.
NOTE:
lIn this step, CONSULT-II reads injector adjustment values stored in ECM and displays the values on
the CONSULT-II screen. This is for checking if injector adjustment values are written onto ECM memory
correctly.
Example: Injector adjustment value = D021ABCD1A061234000000000000E6
