TROUBLE DIAGNOSES FOR SYMPTOMS
BR-71

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.

Fuel Injection System
SYSTEM DESCRIPTION
Three types of fuel injection control are provided to accommodate engine operating conditions; normal control,
idle control and start control. The ECM determines the appropriate fuel injection control. Under each control,
the amount of fuel injected is compensated to improve engine performance. The ECM performs duty control
on the electric governor (built into the fuel injection pump) according to sensor signals to compensate the
amount of fuel injected to the preset value.

When the ECM receives a start signal from the ignition switch, the
ECM adapts the fuel injection system for the start control. The
amount of fuel injected at engine starting is a preset program value
in the ECM. The program is determined by the engine speed and
engine coolant temperature.
For better startability under cool engine conditions, the lower the
coolant temperature becomes, the greater the amount of fuel
injected. The ECM ends the start control when the engine speed
reaches 400 rpm (for M/T models), 600 rpm (for A/T models) and
shifts the control to the normal or idle control.
