3. CAUTIONS FOR DI ENGINE
1) Cautions for DI Engine
This chapter describes the cautions for DI engine equipped vehicle. This includes the water separation
from engine, warning lights, symptoms when engine malfunctioning, causes and actions.
DI Engine 1.
Comparatively conventional diesel engines, DI engine controls the fuel injection and timing electrically,
delivers high power and reduces less emission.
System Safety Mode 2.
When a severe failure has been occurred in a vehicle, the system safety mode is activated to protect
the system. It reduces the driving force, restricts the engine speed (rpm) and stops engine operation.
Refer to "Diagnosis" section in this manual.
Engine CHECK Warning Lamp 3.
The Engine CHECK warning lamp on the instrument cluster comes on when the fuel or
major electronic systems of the engine are not working properly. As a result, the
engine’s power output may decrease or the engine may stall.
Water Separator Warning Lamp
4.
When the water level inside water separator in fuel filter exceeds a certain level (approx.
45 cc), this warning light comes on and buzzer sounds.
Also, the driving force of the vehicle decreases (torque reduction). If these conditions
occur, immediately drain the water from fuel filter.

2. CHECKING CABLES AND WIRES
Check for loose connection or rust.
Check terminals and wires for corrosion due to electrolyte leakage.
Check terminals and wires for open circuit.
Check the wire insulation and coat for damage, cracks or deterioration.
Check if the conductive parts of the terminals do not contact with vehicle body or other metal
parts.
Check that the grounding part has continuity with mounting bolts and vehicle body.
Check that wires are properly routed.
Make sure that wires are securely fixed to avoid contact with sharp body parts and hightemperature
parts, such as the exhaust manifold and exhaust pipes.
The rotating parts, such as fan pulley and fan belt, perturbative parts and wiring should be
secured tightly at regular intervals.
Secure the wiring between the fixed parts, such as the vehicle body, and vibrating parts, such
as the engine, after slackening it slightly to prevent it from being damaged. -
