Operations
CanisterContains activated charcoal to absorb EVAP (Evaporative Emissions) generated in fuel tank.
Cut±off valveLocated in fuel tank. Valve floats and closes when fuel tank is 100 % full.
Purge VSV (Vacuum
Switching Valve)Opens or closes line between canister and intake manifold. ECM uses purge VSV to control EVAP purge flow. In order
to discharge EVAP absorbed by canister to intake manifold, ECM opens purge VSV. EVAP discharge volume to intake
manifold controlled by purge VSV duty cycle ratio (current±carrying time). (Open: ON, Close: OFF)
Refueling valve
Controls EVAP pressure from fuel tank to canister. Valve consists of diaphragm, spring and restrictor (diameter: 0.08
inch). When fuel vapor and pressure inside fuel tank increase, valve opens. While EVAP purged, valve closes and re-
strictor prevents large amount of vacuum from affecting pressure in fuel tank. Valve opened while refueling. When valve
open, adding fuel into fuel tank possible.
Roll±over valveLocated in fuel tank. Valve closes by its own weight when vehicle overturns to prevent fuel from spilling out.
Service portUsed for connecting vacuum gauge for inspecting EVAP system.
Soak timerBuilt into ECM. To ensure accurate EVAP monitor, measures 5 hours* after ignition switch turned to OFF. This allows
fuel to cool down, stabilizing Fuel Tank Pressure (FTP). When approx. 5 hours
* elapsed, ECM activates.
Pump moduleConsists of (a) to (d) below. Pump module cannot be disassembled.
(a) Vent valve
Vents and closes EVAP system. When ECM turns valve ON, EVAP system closed. When, ECM turns valve OFF, EVAP
system vented. Negative pressure (vacuum) created in EVAP system to check for EVAP leaks by closing purge VSV,
turning on vent valve (closed) and operating vacuum pump (refer to fig. 1).
(b) Pressure sensorIndicates pressure as voltages. ECM supplies regulated 5 V to pressure sensor, and uses feedback from sensor to
monitor EVAP system pressure (refer to fig 2).
(c) Vacuum pumpCreates negative pressure (vacuum) in EVAP system for leak check.
(d) 0.02 inch orificeHas opening with 0.02 inch diameter. Vacuum produced through orifice by closing purge VSV, turning off vent valve and
operating vacuum pump, to monitor 0.02 inch leak pressure. 0.02 inch leak pressure indicates small leak of EVAP.
HINT:
*:If the engine coolant temperature is not below 35C after 5 hours after the ignition switch is turned off, the
monitor check starts 2 hours later. If it is still not below 35C 7 hours after the ignition switch is turned off,
the monitor check starts 2.5 hours later.

3. DESCRIPTION OF OCCUPANT CLASSIFICATION SYSTEM
(a) GENERAL DESCRIPTION.
(1) In the occupant classification system, the occupant classification ECU calculates the weight of
the occupant based on a signal from the occupant classification sensor. This system recognizes
the occupant to be a child if it detects a weight of less than 36 kg (79.37 lb), and disables the
front and side airbags.
(2) This system is mainly comprised of 4 occupant classification sensors that detect the load on the
front passenger seat. The occupant classification ECU controls the system, and the passenger
airbag ON/OFF indicator indicates the ON/OFF condition of the front passenger airbag assembly
and side airbag assembly (passenger side).
(b) OCCUPANT CLASSIFICATION SENSOR.
The occupant classification sensors are installed on 4 brackets connecting the seat rail and seat frame.
Accordingly, when load is applied to the passenger seat by an occupant sitting in it, the occupant classi-
fication sensors register a distortion.

(5) Perform the sensitivity check by following the
prompts on the tester screen shown in 2 pages lat-
er.
(6) Confirm that the beginning sensor reading is within
the standard value.
OK:
Standard value: ±3.2 to 3.2 kg (±7 to 7 lb)
(7) Place a 30 kg (66.14 lb) weight (eg. a 30 kg (66.14
lb) of lead mass) onto the passenger seat.
(8) Confirm that the sensitivity is within the standard
value.
OK:
Standard value: 27 to 33 kg (59.52 to 72.75 lb)
HINT:

When performing the sensitivity check, use a solid metal
weight (the check result may not appear properly if the
weight made from liquid is used).

When the sensitivity deviates from the standard value, re-
tighten the bolts of the passenger seat taking care not to
deform the seat rail. After performing this procedure, if the
sensitivity is not within the standard value, replace the
front seat assembly RH.

When zero point calibration has not finished normally, re-
place the front seat assembly RH.

INSPECTION
1. INSPECT RELIEF VALVE
Coat the valve with engine oil and check that it falls smoothly
into the valve hole by its own weight.
If it doesn't, replace the relief valve. If necessary, replace the oil
pump assembly.
2. INSPECT DRIVE AND DRIVEN ROTORS
(a) Place the drive and driven rotors into the oil pump body.
(see page LU±14)
(b) Inspect the rotors for the body clearance.
Using a feeler gauge, measure the clearance between
the drive and driven rotor tips.
Standard tip clearance:
0.060 to 0.180 mm (0.0024 to 0.0071 in.)
Maximum tip clearance: 0.18 mm (0.0071 in.)
If the tip clearance is greater than maximum, replace the rotors
as a set.
(c) Inspect the rotors for the side clearance.
Using a feeler gauge and precision straight edge, mea-
sure the clearance between the rotors and precision
straight edge.
Side clearance:
0.030 to 0.090 mm (0.0012 to 0.0035 in.)
Maximum body clearance: 0.09 mm (0.0035 in.)
If the side clearance is greater than maximum, replace the ro-
tors as a set. If necessary, replace the oil pump assembly.
(d) Inspect the rotor for the body clearance.
Using a feeler gauge, measure the clearance between
the driven rotor and body.
Standard body clearance:
0.250 to 0.325 mm (0.0098 to 0.0128 in.)
Maximum body clearance: 0.325 mm (0.0128 in.)
If the body clearance is greater than maximum, replace the ro-
tors as a set. If necessary, replace the oil pump assembly.
(e) Remove the drive and drive rotors.
