+All dimensions indicated in ®gures are actual ones.
+When using a tracking gauge, adjust both pointers to equal length. Then check the pointers and gauge
itself to make sure there is no free play.
+When a measuring tape is used, check to be sure there is no elongation, twisting or bending.
+Measurements should be taken at the center of the mounting holes.
+An asterisk (*) following the value at the measuring point indicates that the measuring point on the other
side is symmetrically the same value.
+The coordinates of the measurement points are the distances measured from the standard line of ``X'', ``Y''
and ``Z''.

INSPECTION
Hoses and connectors
+Check condition of vacuum hoses and connections.
+Check vacuum hoses and check valve for air tightness.
Vacuum hose check valve
1. Remove the vacuum hose.
2. Blow air through one end (booster side) of the vacuum hose
and make sure that air passage continuity exists.
3. Blow air through the other end (engine side) of the vacuum
hose and make sure that air passage continuity does not exist.
Check valve
1. Remove the vacuum hose.
2. Check the condition of the check valve using a handy vacuum
pump.

When you read wiring diagrams:
+ Read GI section, ``HOW TO READ WIRING DIAGRAMS''.
+ See EL section, ``POWER SUPPLY ROUTING'' for power distribution circuit.
When you perform trouble diagnoses, read GI section, ``HOW TO FOLLOW FLOW CHART IN
TROUBLE DIAGNOSES'' and ``HOW TO PERFORM EFFICIENT DIAGNOSIS FOR AN ELECTRICAL

PRECAUTIONS AND PREPARATION

Engine Fuel & Emission Control System
SEF656V
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.
