INSPECTION PROCEDURE
TOYOTA hand±held tester
1 Connect TOYOTA hand±held tester and check operation of VSV for ACIS.
PREPARATION:
(a) Remove the fuse cover on the instrument panel.
(b) Connect the TOYOTA hand±held tester to the DLC3.
(c) Turn the ignition switch ON and push the TOYOTA hand±
held tester main switch ON.
(d) Select the ACTIVE TEST mode on the TOYOTA hand±
held tester.
CHECK:
Check operation of VSV when VSV is operated by the TOYOTA
hand±held tester.
OK:
VSV is ON:
Air from pipe E is flowing out through pipe F.
VSV is OFF:
Air from pipe E is flowing out through the air filter.
OK Check for vacuum tank (See page SF±51).
NG
2 Check VSV for ACIS (See page SF±60).
NG Replace VSV for ACIS.

INSPECTION
1. INSPECT EGR SYSTEM
(a) Inspect and clean the filter in the EGR vacuum modulator.
(1) Remove the cap and filter.
(2) Check the filter for contamination or damage.
(3) Using compressed air, clean the filter.
(4) Reinstall the filter and cap.
HINT:
Install the filter with the coarser surface facing the atmospheric
side (outward).
(b) Using a 3±way connector, connect a vacuum gauge to the
hose between the EGR valve and VSV.
(c) Inspect seating of the EGR valve.
Start the engine and check that the engine starts and runs
at idle.
(d) Using SST, connect terminals TE1 and E1 of the DLC1.
SST 09843±18020
(e) Inspect the VSV operation with the cold engine.
(1) The engine coolant temperature should be below
55°C (131°F).
(2) Check that the vacuum gauge indicates zero at
2,500 rpm.
(f) Inspect the operation of the VSV and EGR vacuum modu-
lator with the hot engine.
(1) Warm up the engine to above 60°C (140°F).
(2) Check that the vacuum gauge indicates low vacu-
um at 2,500 rpm.
(3) Disconnect the vacuum hose port R of the EGR vac-
uum modulator and connect port R directly to the in-
take manifold with another hose.
(4) Check that the vacuum gauge indicates high vacu-
um at 2,500 rpm.
