5. DLC3 (Data Link Connector 3)
(a) The vehicle's ECM uses ISO 15765-4 for
communication protocol. The terminal arrangement
of the DLC3 complies with SAE J1962 and matches
the ISO 15765-4 format.
NOTICE:
*: Before measuring the resistance, leave the
vehicle as is for at least 1 minute and do not
operate the ignition switch, any other switches
or the doors.
HINT:
The DLC3 is the interface prepared for reading
various data from the vehicle's ECM. After
connecting the cable of an intelligent tester, turn the
ignition switch to the ON position and turn the tester
ON.
• If a communication failure message is displayed
on the tester screen (on the tester: UNABLE TO
CONNECT TO VEHICLE), a problem exists in
either the vehicle or tester. In order to identify the
location of the problem, connect the tester to
another vehicle.
• If communication is normal: Inspect the DLC3 on
the original vehicle.
• If communication is impossible: The problem is
probably in the tester itself. Consult the Service
Department listed in the instruction manual.
6. BATTERY VOLTAGE
Battery Voltage:
11 to 14 V
If the voltage is below 11 V, recharge the battery before
proceeding to the next step.
7. MIL (Malfunction Indicator Lamp)
(a) The MIL is illuminated when the ignition switch is
first turned to the ON position (the engine is not
running).

2GR-FE ENGINE CONTROL SYSTEM – SFI SYSTEMES–419
ES
Cut-off valve Located 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 is controlled by purge VSV duty cycle ratio
(current-carrying time). (Open: ON, Close: OFF)
Refueling valveControls 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 is purged, valve closes and restrictor prevents a large amount of vacuum from
affecting pressure in fuel tank. Valve is opened while refueling. When valve is open, adding fuel into
fuel tank is possible.
Roll-over valveLocated in fuel tank. Valve closes by its own weight when vehicle overturns to prevent fuel from
spilling out.
Service port Used for connecting vacuum gauge for inspecting EVAP system.
Soak timerBuilt into ECM. To ensure accurate EVAP monitor, measures 5 hours (+/- 15 min.) after ignition
switch is turned off. This allows fuel to cool down, stabilizing Fuel Tank Pressure (FTP). When
approx. 5 hours elapsed, ECM activates.
Canister pump module Consists of (a) to (d) below. Pump module cannot be disassembled.
(a) Vent valveVents and closes EVAP system. When ECM turns valve ON, EVAP system is closed. When ECM
turns valve OFF, EVAP system is vented. Negative pressure (vacuum) is created in EVAP system
to check for EVAP leaks by closing purge VSV and vent valve (closed), and operating vacuum
pump are turned on (refer to fig. 1).
(b) Canister 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 pump Creates negative pressure (vacuum) in EVAP system for leak check.
(d) 0.02 inch orificeHas an opening with 0.02 inch diameter. Vacuum is 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 a small leak of EVAP. Component Operation
