QUICK REFERENCE INDEX

1. Ensure vehicle is unladen condition*.* Fuel, radiator coolant and engine oil full. Spare tire, jack,hand tools and mats in designated positions.
2. Have a driver sit in the driver's seat and one person sit on the rear end. Then have the person on the rear end slowly get off
the vehicle. This is necessary to stabilize suspension de¯ec-
tion.
3. Gradually depress brake pedal and attach a lever to the stop- per bolt, then adjust length ``L'' as follows:Length ``L'': Approx. 175.2 - 178.2 mm (6.90 - 7.02 in)
4. Remove front LH tire.
5. Connect tool to air bleeders on front LH brake caliper and rear LH or RH brake wheel cylinder.
6. Install front LH tire.
Before installing front LH tire, con®rm the tool is not touching
the front LH wheel.
7. Bleed air from Tool.
8. Raise front brake pressure to 4,904 kPa (49.0 bar, 50 kg/cm
2,
711 psi) and 9,807 kPa (98.1 bar, 100 kg/cm2, 1,422 psi) and
check rear brake pressure. Rear brake pressure: Refer to table on next page.

PRECAUTIONS AND PREPARATION
EC-5

Precautions
+Before connecting or disconnecting the ECM harness
connector, turn ignition switch OFF and disconnect nega-
tive battery terminal. Failure to do so may damage the ECM
because battery voltage is applied to ECM even if ignition
switch is turned off.
+When connecting ECM harness connector, tighten secur-
ing bolt until the gap between orange indicators disap-
pears.
: 3.0 - 5.0 Nzm (0.3 - 0.5 kg-m, 26 - 43 in-lb)
+When connecting or disconnecting pin connectors into or
from ECM, take care not to damage pin terminals (bend or
break).
Make sure that there are not any bends or breaks on ECM
pin terminal, when connecting pin connectors.
+Before replacing ECM, perform Terminals and Reference
Value inspection and make sure ECM functions properly.
Refer to EC-54.
+If MIL illuminates or blinks irregularly when engine is
running, water may have accumulated in fuel ®lter. Drain
water from fuel ®lter. If this does not correct the problem,
perform speci®ed trouble diagnostic procedures.
+After performing each TROUBLE DIAGNOSIS, perform
``OVERALL FUNCTION CHECK'' or ``DTC (Diagnostic
Trouble Code) CONFIRMATION PROCEDURE''.
The DTC should not be displayed in the ``DTC CONFIRMA-
TION PROCEDUREº if the repair is completed. The ``OVER-
ALL FUNCTION CHECK'' should be a good result if the
repair is completed.
