INSPECTION
1. INSPECT VACUUM REGULATING VALVE ASSY
(a) Inspect E±VRV for open circuit
(1) Using an ohmmeter, measure resistance between
the terminals.
Resistance:
10 to 14
at 20
C (68
F)
(b) Inspect E±VRV for ground
(1) Using an ohmmeter, check that there is no continu-
ity between each terminal and the body.
Specified condition : No continuity
(c) Inspect E±VRV for air tightness
(1) Apply vacuum to the vacuum output port. Check
that the needle of vacuum pump indicates an in-
crease of 66.7 kPa (500 mmHg, 19.7 in.Hg) or
more.
If the air tightness is not as specified, replace the E±VRV.
(d) Inspect E±VRV operation
(1) Apply about 4 dry batteries of 1.5V in series.
(2) Check that the need does not move when vacuum
is applied to the vacuum outlet port.
If operation is not as specified, replace the E±VRV.

EGR SYSTEM (1CD±FTV)
ON±VEHICLE INSPECTION
HINT:
In a malfunction where the EGR system is always on, black smoke or white smoke may be emitted from the
exhaust pipe. If this occurs, inspect the EGR system as well.
1. INSPECT SEATING OF EGR VALVE
(a) Start the engine and check that it starts and runs at idle.
2. INSPECT HOT ENGINE CONDITION (WHEN USING HAND±HELD TESTER)
(a) Connect the hand±held tester to the DLC3.
(b) Start the engine and run it at idle.
(c) Select the ACTIVE TEST mode on the hand±held tester.
HINT:
Refer to the hand±held tester operator's manual for further details.
(d) Warm up the engine, the coolant temperature should be above 75
C (109
F) and bellow 90
C
(194
F).
(e) Check that the AFM reading is 5
ega
8 g/s with the engine idling.
(f) Operate the EGR valve with a hand±held tester. Regulate the valve opening angle to 0, and check that
the AFM reading is 11
ega
17 g/s..
If the AFM reading is out of range in either (e) or (f), replace the EGR valve.
If the AFM is out of range in both (e) and (f), replace the air flow meter (air cleaner) and check the EGR valve
operation again.
3. INSPECT HOT ENGINE CONDITION (WHEN NOT USING HAND±HELD TESTER)
(a) Install the vacuum gauge.
(1) Using a 3±way connector, connect a vacuum gauge to the hose between the intake manifold and
the turbo pressure sensor.
(b) Warm up the engine, the coolant temperature should be above 75
C (109
F) and bellow 90
C
(194
F).
(c) Check that the vacuum gauge indicates about more than 2.5 kPa (19 mmHg 0.7 in Hg).
(d) Stop the engine (IG OFF), remove the EGR valve connector, restart the engine, and check that load
under idling is less than 2.5 kPa (19 mmHg 0.7 in Hg).
If the load pressure exceeds the above value, replace the EGR valve.

(8) Oil or water should not be put on the front seat outer belt and the front seat outer belt should be
cleaned with the appropriate detergents.
(i) AIRBAG SENSOR ASSEMBLY
(1) Never reuse the airbag sensor assembly involved in a collision where the SRS has deployed.
(2) The connectors to the airbag sensor assembly should be connected or disconnected with the
sensor mounted on the floor. If the connectors are connected or disconnected while the airbag
sensor assembly is not mounted to the floor, it could cause an undesired ignition of the supple-
mental restraint system.
(3) Work must be started after 90 seconds from the time the ignition switch is turned to the ºLOCKº
position and the negative (±) terminal cable is disconnected from the battery, even if only loosen-
ing the set bolts of the airbag sensor assembly.
(j) WIRE HARNESS AND CONNECTOR
(1) The SRS wire harness is integrated with the instrument panel wire harness assembly. All connec-
tors in the system are a standard yellow color. If the SRS wire harness becomes disconnected
or the connector becomes broken due to an accident, etc., repair or replace it.
3. ELECTRONIC CONTROL
(a) REMOVAL AND INSTALLATION OF BATTERY TERMI-
NAL
(1) Before performing electronic work, disconnect the
battery negative (±) terminal cable beforehand in
order to prevent it from shorting and burning out.
(2) When disconnecting and installing the terminal
cable, turn the ignition switch and lighting switch
OFF, and loosen the terminal nut completely. Per-
form these operations without twisting or prying the
terminal.
(3) When the battery terminal cable is removed, the
memories of the clock, radio, DTCs, etc. are erased.
So before removing it, check them and make a note
of their settings.
(4) When the battery negative (±) terminal cable is dis-
connected, memories of various systems are
erased. Therefore, refer to the PRE±CHECK for
each system to make sure whether or not the sys-
tem needs to be initialized after the battery negative
