Scan Tool Data Definitions
COOLANT TEMP (ENGINE COOLANT
TEMPERATURE, °C, °F)
It is detected by engine coolant temp. sensor.
INTAKE AIR TEMP. (°C, °F)
It is detected by intake air temp. sensor.
ENGINE SPEED (rpm)
It is computed by reference pulses from the camshaft
position sensor.
DESIRED IDLE (DESIRED IDLE SPEED, rpm)
The Desired Idle Speed is an ECM internal parameter
which indicates the ECM requested idle. If the engine is
not running, this number is not valid.
MAF (MASS AIR FLOW RATE, g/s, lb/min.)
It represents total mass of air entering intake manifold
which is measured by mass air flow sensor.
CALC LOAD (CALCULATED LOAD VALUE, %)
Engine load displayed as a percentage of maximum
possible load. Value is calculated mathematically using
the formula: actual (current) intake air volume ÷
maximum possible intake air volume × 100%
MAP (MANIFOLD ABSOLUTE PRESSURE, in.Hg,
kPa)
This value indicates how much correction is necessary
to keep the air/fuel mixture stoichiometrical.
It is detected by manifold absolute pressure sensor.
THROTTLE POS (RELATIVE THROTTLE POSITION,
%)
When throttle position sensor is at fully closed position,
throttle opening is indicated as 0 – 12% and 90 – 100%
full open position.
BAROMETRIC PRESS (kPa, in.Hg)
This parameter represents a measurement of barometric
air pressure and is used for altitude correction of the fuel
injection quantity.
FUEL TANK LEVEL (%)
This parameter indicates approximate fuel level in fuel
tank. As detectable range of fuel level sensor is set as 0
to 100%, however, with some models whose fuel tank
capacity is smaller, indicated fuel level may be only 70%
even when fuel tank is full.
BATTERY VOLTAGE (V)
This parameter indicates battery positive voltage
inputted from main relay to ECM.
BRAKE SW (ON/OFF)
This parameter indicates the state of the brake switch.FUEL SYSTEM B1 (FUEL SYSTEM STATUS)
Air/fuel ratio feedback loop status displayed as one of
the followings.
OPEN: Open-loop has not yet satisfied conditions to go
closed loop.
CLOSED: Closed-loop using oxygen sensor(s) as
feedback for fuel control.
OPEN-DRIVE COND: Open-loop due to driving
conditions (Power enrichment, etc.).
OPEN SYS FAULT: Open-loop due to detected system
fault.

exhaust manifold (pre-catalyst.)
O2S SENSOR B1 S2 (HEATED OXYGEN SENSOR-2,
V)
It indicates output voltage of HO2S-2 installed on
exhaust pipe (post-catalyst). It is used to detect catalyst
deterioration.
SHORT FT B1 (SHORT TERM FUEL TRIM, %)
Short term fuel trim value represents short term
corrections to the air/fuel mixture computation. A value
of 0 indicates no correction, a value greater than 0
means an enrichment correction, and a value less than 0
implies an enleanment correction.
LONG FT B1 (LONG TERM FUEL TRIM, %)
Long term fuel trim value represents long term
corrections to the air/fuel mixture computation. A value
of 0 indicates no correction, a value greater than 0
means an enrichment correction, and a value less than 0
implies an enleanment correction.
TOTAL FUEL TRIM B1 (%)
The value of Total Fuel Trim is obtained by calculating
based on values of Short Term Fuel Trim and Long Term
Fuel Trim. This value indicates how much correction is
necessary to keep the air/fuel mixture stoichiometrical.

Engine Cooling System
General Description
Cooling System DescriptionS6RW0D1601001
The cooling system consists of the radiator cap, radiator,
coolant reservoir, hoses, water pump, cooling fan and
thermostat. The radiator is of tube-and-fin type.
Coolant DescriptionS6RW0D1601002
WARNING!
• Do not remove radiator cap to check
engine coolant level; check coolant
visually at the see-through coolant
reservoir. Coolant should be added only to
reservoir as necessary.
• As long as there is pressure in the cooling
system, the temperature can be
considerably higher than the boiling
temperature of the solution in the radiator
without causing the solution to boil.
Removal of the radiator cap while engine is
hot and pressure is high will cause the
solution to boil instantaneously and
possibly with explosive force, spewing the
solution over engine, fenders and person
removing cap. If the solution contains
flammable anti-freeze such as alcohol (not
recommended for use at any time), there is
also the possibility of causing a serious
fire.
• Check to make sure that engine coolant
temperature is cold before removing any
part of cooling system.
• Also be sure to disconnect negative cable
from battery terminal before removing any
part.

The coolant recovery system is standard. The coolant in
the radiator expands with heat, and the coolant is
overflowed to the reservoir.
When the system cools down, the coolant is drawn back
into the radiator.
The cooling system has been filled with a quality coolant
that is a 50/50 mixture of water and ethylene glycol
antifreeze.
This 50/50 mixture coolant solution provides freezing
protection to –36 °C (–33 °F).
• Maintain cooling system freeze protection at –36 °C (–
33 °F) to ensure protection against corrosion and loss
of coolant from boiling. This should be done even if
freezing temperatures are not expected.
• Add ethylene glycol base coolant when coolant has to
be added because of coolant loss or to provide added
protection against freezing at temperature lower than
–36 °C (–33 °F).
NOTE
• Alcohol or methanol base coolant or plain
water alone should not be used in cooling
system at any time as damage to cooling
system could occur.
• Coolant must be mixed with demineralized
water or distilled water.

Charging System
General Description
Battery DescriptionS6RW0D1A01001
The battery has three major functions in the electrical
system.
• It is a source of electrical energy for cranking the
engine.
• It acts as a voltage stabilizer for the electrical system.
• It can, for a limited time, provide energy when the
electrical load exceeds the output of the generator.
Carrier and Hold-Down
The battery carrier should be in good condition so that it
will support the battery securely and keep it level. Before
installing the battery, the battery carrier and hold-down
clamp should be clean and free from corrosion and
make certain there are no parts in carrier.
To prevent the battery from shaking in its carrier, the
hold-down bolts should be tight enough but not over-
tightened.
Electrolyte Freezing
The freezing point of electrolyte depends on its specific
gravity. Since freezing may ruin a battery, it should be
protected against freezing by keeping it in a fully
charged condition. If a battery is frozen accidentally, it
should not be charged until it is warmed.
Sulfation
If the battery is allowed to stand for a long period in
discharged condition, the lead sulfate becomes
converted into a hard, crystalline substance, which will
not easily turn back to the active material again during
the subsequent recharging. “Sulfation” means the result
as well as the process of that reaction. Such a battery
can be revived by very slow charging and may be
restored to usable condition but its capacity is lower than
before.Built-In Indicator (If Equipped)
The battery has a built-in temperature compensated
indicator in the top of the battery. This indicator is to be
used with the following diagnostic procedure. When
checking the indicator, make sure that the battery has a
clean top. A light may be needed in some poorly-lit
areas.
Three types of indication available under normal
operation are as follows.
•Green dot
Battery is sufficiently charged for testing.
•Dark
Battery must be charged before testing. If there is a
cranking complaint, battery should be tested as
described in “Battery Inspection”. Charging and
electrical systems should also be checked at this time.
•Clear or light yellow
This means that fluid level is below the bottom of
hydrometer. Its possible cause is excessive or
prolonged charging, a broken case, excessive tipping
or normal battery deterioration. When the battery is
found in such condition, it is possible that high
charging voltage is caused by the faulty charging
system and therefore, charging and electrical systems
need to be checked. If there is a trouble in cranking
and its cause lies in the battery, it should be replaced.
