2. INSPECT IGNITION TIMING
(a) When using a hand±held tester.
(1) Connect a hand±held tester to the Controller Area
Network Vehicle Interface Module (CAN VIM). Then
connect the CAN VIM to the Date Link Connector 3
(DLC3).
(2) Please refer to the hand±held tester operator's
manual for further details.

INSPECTION
1. INSPECT LINES AND CONNECTIONS
Visually check for loose connections, sharp bends or damage.
2. INSPECT FUEL TANK
Visually check for deformation, cracks or fuel leakage.
3. INSPECT FUEL TANK CAP
Visually check if the cap and/or gasket are deformed or dam-
aged.
If necessary, repair or replace the cap.
4. INSPECT EVAP SYSTEM LINE
(a) Warm up the engine to normal operating temperature and
stop the engine.
(b) Install a vacuum gauge (EVAP control system test equip-
ment vacuum gauge) into the EVAP service port on the
purge line.
(c) When using a hand±held tester:
Operation of the VSV for EVAP.
(1) Connect a hand±held tester to the Controller Area
Network Vehicle Interface Module (CAN VIM). Then
connect the CAN VIM to the Date Link Connector 3
(DLC3).
(2) Start the engine.
(3) Turn the hand±held tester ON.

(d) When not using a hand±held tester:
Operation of the VSV for the EVAP.
(1) Disconnect the VSV for the EVAP connector.
(2) Connect leads from the positive (+) and negative (±)
battery terminals to the VSV for EVAP terminals.
(3) Start the engine.
(e) Check the vacuum when the engine idles.
Vacuum:
Maintain between 0.368 and 19.713 in.Hg (5 to 268
in.Aq) for over 5 seconds
HINT:
If the vacuum does not change, the hose connecting the VSV
and the service port is loose or blocked, or the VSV is malfunc-
tioning.
(f) When using a hand±held tester:
Conclude operation of the VSV for EVAP.
(1) Stop the engine.
(2) Disconnect the hand±held tester from the DLC3.
(g) When not using a hand±held tester:
Conclude operation of the VSV for EVAP.
(1) Stop the engine.
(2) Disconnect the positive (+) and negative (±) leads
of the battery from the VSV for EVAP terminals.
(3) Connect the VSV for EVAP connector.
(h) Disconnect the vacuum gauge from the EVAP service
port on the purge line.
(i) Connect a pressure gauge to the EVAP service port on
the purge line.
(j) Check the pressure.
(1) Prepare a rubber hose that has an inside diameter
of 15 to 18.5 mm.
(2) Disconnect the atmospheric side hose of the pump
module.
(3) Connect the prepared rubber hose to the pump
module, and pinch the rubber hose with the clip to
prevent air from entering into the canister passage.

(j) Check that there is any fuel leak after maintenance any-
where on the fuel system.
(1) Connect a hand±held tester to the Controller Area
Network Vehicle Interface Module (CAN VIM). Then
connect the CAN VIM to the Date Link Connector 3
(DLC3).
(2) Turn the ignition switch ON and push the hand±held
tester main switch ON.
NOTICE:
Do not start the engine.
(3) Enter the following menus: DIAGNOSIS / EN-
HANCED OBDII / ACTIVE TEST / FUEL PUMP /
SPD.
(4) Please refer to the hand±held tester operator's
manual for further details.
(5) Pinch the fuel return hose.
The pressure in the high pressure line will rise to
approx. 392 kPa (4 kgf/cm
2, 57 psi). In this state,
check to see that there are no leaks from any part
of the fuel system.
NOTICE:
Always pinch the hose. Avoid bending as it may cause the
hose to crack.
(6) Turn the ignition switch OFF.
(7) Disconnect the hand±held tester and CAN VIM
from the DLC3.
