due to receiving external noise, degraded operation of ICs,
etc.
IKeep ECM parts and harnesses dry.
IBefore replacing ECM, perform Terminals and Reference
Value inspection and make sure ECM functions properly.
Refer to EC-69.
IIf MI (MIL) illuminates or blinks irregularly when engine is
running, water may have accumulated in fuel filter. Drain
water from fuel filter. If this does not correct the problem,
perform specified trouble diagnostic procedures.
IAfter performing each TROUBLE DIAGNOSIS, perform
ªDTC Confirmation Procedureº or ªOverall Function
Checkº.
The DTC should not be displayed in the ªDTC Confirmation
Procedureº if the repair is completed. The ªOverall Func-
tion Checkº should be a good result if the repair is com-
pleted.
IWhen measuring ECM signals with a circuit tester, never
allow the two tester probes to contact.
Accidental contact of probes will cause a short circuit and
damage the ECM power transistor.
IDo not use ECM ground terminals when measuring input/
output voltage. Doing so may result in damage to the
ECM's transistor. Use a ground other than ECM terminals,
such as the ground.

Crankcase Ventilation System
DESCRIPTION
In this system, blow-by gas is sucked into the air inlet pipe after oil
separation by oil separator in the rocker cover.
INSPECTION
Ventilation hose
1. Check hoses and hose connections for leaks.
2. Disconnect all hoses and clean with compressed air. If any
hose cannot be freed of obstructions, replace.
