Precautions for Multiport Fuel Injection System
or Engine Control System
1. Before connecting or disconnecting any harness connector forthe multiport fuel injection system or ECM (Engine Control
Module):
Turn ignition switch to ªOFFº position.
Disconnect negative battery terminal.
Otherwise, there may be damage to ECM.
2. Before disconnecting pressurized fuel line from fuel pump to injectors, be sure to release fuel pressure to eliminate danger.
3. Be careful not to jar components such as control unit and air flow meter.
Precautions for Catalyst
If a large amount of unburned fuel enters the converter, the con-
verter temperature will rise to excessively high values. To prevent
this, follow the procedure below:
1. Use unleaded gasoline only. Leaded gasoline will seriouslydamage the catalytic converter.
2. When checking for ignition spark or measuring engine compression, perform tests quickly and only when necessary.
3. Do not run engine when the fuel tank level is low, as a result the engine may misfire causing damage to the converter.
4. Do not place the vehicle on inflammable material. Keep inflam- mable material off the exhaust pipe.
Precautions for Turbocharger
The turbocharger turbine revolves at extremely high speeds and
becomes very hot. Therefore, it is essential to maintain a clean
supply of oil flowing through the turbocharger and to follow all
required maintenance instructions and operating procedures.
For proper operation of the system, follow the procedure below:
1. Always use the recommended oil. Follow the instructions forproper time to change the oil and proper oil level.
2. Avoid accelerating engine to a high rpm immediately after start- ing.
3. If engine had been operating at high rpm for an extended period of time, let it idle for a few minutes prior to shutting it off.

DETECTABLE LINES AND NON-DETECTABLE LINES
In some wiring diagrams, two kinds of lines, representing wires,
with different weight are used.
IA line with regular weight (wider line) represents a ªdetectable
line for DTC (Diagnostic Trouble Code)º. A ªdetectable line for
DTCº is a circuit in which ECM (Engine Control Module) can
detect its malfunctions with the on board diagnostic system.
I A line with less weight (thinner line) represents a ªnon-detect-
able line for DTCº. A ªnon-detectable line for DTCº is a circuit
in which ECM cannot detect its malfunctions with the on board
diagnostic system.

How to Probe Connectors
Connector damage and an intermittent connection can result from
improperly probing of the connector during circuit checks.
The probe of a digital multimeter (DMM) may not correctly fit the
connector cavity. To correctly probe the connector, follow the pro-
cedures below using a ªTº pin. For the best contact grasp the ªTº
pin using an alligator clip.
PROBING FROM HARNESS SIDE
Standard type (not waterproof type) connector should be probed
from harness side with ªTº pin.
IIf the connector has a rear cover such as a ECM connector,
remove the rear cover before probing the terminal.
I Do not probe waterproof connector from harness side.
Damage to the seal between wire and connector may
result.
PROBING FROM TERMINAL SIDE
Female terminal
IThere is a small notch above each female terminal. Probe each
terminal with the ªTº pin through the notch.
Do not insert any object other than the same type male termi-
nal into female terminal.
I Some connectors do not have a notch above each terminal. To
probe each terminal, remove the connector retainer to make
contact space for probing.
Male terminal
Carefully probe the contact surface of each terminal using a ªTº pin.
Do not bend terminal.

stopped.Depress brake pedal.
Start engine, or check with engine run-
ning.Release brake pedal.
Apply parking brake.Depress accelerator pedal.
Release parking brake.Release accelerator pedal.
Check after engine is warmed up suffi-
ciently.
Pin terminal check for SMJ type connec-
tor (e.g. ECM and TCM, etc.)
For details regarding the terminal
arrangement, refer to the foldout page.
Voltage should be measured with a volt-
meter.

Nickel Metal Hydride Battery Replacement
CONSULT-II contains a nickel metal hydride battery. When replacing the battery obey the following:
WARNING:
Replace the nickel metal hydride battery with genuine CONSULT-II battery only. Use of another battery
may present a risk of fire or explosion. The battery may present a fire or chemical burn hazard if mis-
treated. Do not recharge, disassemble of dispose of in fire.
Keep the battery out of reach of children and discard used battery conforming to the local regulations.

Trouble diagnosis of turbocharger
Preliminary check:
Check that the VNT control valve system has no malfunction. Refer
to EC section, ªECM Terminals and Reference Valueº in ªTROUBLE
DIAGNOSIS Ð GENERAL DESCRIPTIONº.
ICheck that the engine oil level is between MIN and MAX of the
dipstick. (When the engine oil amount is more than MAX, the
oil flows into the inlet duct through the blow-by gas passage,
and the turbocharger is misjudged failure.)
I Ask the customer if he/she always runs the vehicle in idle
engine speed to cool the oil down after driving.
I Replace the turbocharger assembly when any malfunction is
found after unit inspections specified in the table below.
I If no malfunction is found after the unit inspections, judge that
the turbocharger body has no failure. Check the other parts
again.
