Preliminary Check
Check brake fluid level in reservoir
tank.
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Low fluid level may indicate brake pad
wear or leakage from brake line.
Check brake line for leakage.

.1: 2WD model only
.2: 4WD model only
.3: If one or more wheels spin on a rough or slippery road for 40 seconds or more, the ABS warning lamp will illuminate. This does
not indicate a malfunction. Only in the case of the short-circuit (Code Nos. 26, 22, 32 and 36), after repair the ABS warning
lamp also illuminates when the ignition switch is turned ``ON''. In this case, drive the vehicle at speeds greater than 30 km/h (19
MPH) for approximately 1 minute as specified in ``SELF-DIAGNOSIS PROCEDURE'', BR-53. Check to ensure that the ABS
warning lamp goes out while the vehicle is being driven.
.4: The trouble code ``57'', which refers to a low power supply voltage, does not indicate that the ABS control unit is malfunctioning.
Do not replace the ABS control unit with a new one.
.5: The trouble code ``61'' can sometimes appear when the ABS motor is not properly grounded. If it appears, be sure to check the
condition of the ABS motor ground circuit connection.

Fuel Pressure Release
Before disconnecting fuel line, release fuel pressure from
fuel line to eliminate danger.
1. Start engine.
2. Perform ``FUEL PRESSURE RELEASE'' in ``WORK
SUPPORT'' mode with CONSULT.
(Touch ``START'' and after engine stalls, crank it two or
three times to release all fuel pressure.)
3. Turn ignition switch off.
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------OR-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
1. Remove fuse for fuel pump.
2. Start engine.
3. After engine stalls, crank it two or three times to release
all fuel pressure.
4. Turn ignition switch off and reconnect fuel pump fuse.
Fuel Pressure Check
lWhen reconnecting fuel line, always use new clamps.
lMake sure that clamp screw does not contact adjacent
parts.
lUse a torque driver to tighten clamps.
lUse Pressure Gauge to check fuel pressure.
1. Release fuel pressure to zero, refer to above.
2. Disconnect fuel hose between fuel filter and fuel tube (engine
side).
3. Install pressure gauge between fuel filter and fuel tube.
4. Start engine and check for fuel leakage.
5. Read the indication of fuel pressure gauge.
At idling:
Approximately 235 kPa (2.35 bar, 2.4 kg/cm
2,34
psi)
A few seconds after ignition switch is turned OFF to
ON:
Approximately 294 kPa (2.94 bar, 3.0 kg/cm
2,43
psi)
6. Stop engine and disconnect fuel pressure regulator vacuum
hose from intake manifold.
7. Plug intake manifold with a rubber cap.
8. Connect variable vacuum source to fuel pressure regulator.
9. Start engine and read indication of fuel pressure gauge as
vacuum is changed.
Fuel pressure should decrease as vacuum increases. If
results are unsatisfactory, replace fuel pressure regulator.
