(c) Prepare the hand-held tester.
(d) Connect the hand-held to DLC3.
(e) Turn the ignition switch ON and the hand-held tester
main switch ON.
(f) Use the hand-held tester to check the DTCs, note them
down. (For opening instructions, see the hand-held tes-
ter 's intrusion book).
10. DATA LIST
HINT:
By the DATA LIST displayed on the Hand-held tester, you can read the value of the switch, sensor, actuator
and so on without removing any parts. Reading the DATA LIST as a first step of troubleshooting is one of
the method to shorten the labor time.
(a) Turn the ignition switch OFF.
(b) Connect the hand-held tester to DLC3.
(c) Turn the ignition switch ON.
(d) According to the display on the tester, read the ºDATA LISTº.

11. ACTIVE TEST
HINT:
Performing ACTIVE TEST using the Hand-held tester allows the relay, and so on to operate without remov-
ing any parts. Performing ACTIVE TEST as a first step of troubleshooting is one of the method to shorten
the labor time.
DATA LIST can be displayed during ACTIVE TEST.
(a) Turn the ignition switch OFF.
(b) Connect the Hand-held tester to DLC3.
(c) Turn the ignition switch ON.
(d) According to the display on tester, perform the ºACTIVE TESTº.

(4) While holding the air inlet port closed, apply vacuum
(3.43 kPa, 25.7 mmHg, 1.01 in Hg) to the EVAP port
and check that air flows into the purge port.
If operation is not as specified, replace the charcoal canister.
(5) Remove the cap from the vent port.

6. TROUBLESHOOTING
HINT:
If the CO/HC concentration does not comply with the regula-
tions, perform troubleshooting in the order given below.
See the table below for possible causes, and then inspect and
correct the applicable causes if necessary.
COHCProblemsCauses
NormalHighRough idle1. Faulty ignitions:

Incorrect timing

Fouled, shorted or improperly gapped plugs
2. Incorrect valve clearance
3. Leaky intake and exhaust valves
4. Leaky cylinders
LowHighRough idle
(fluctuating HC reading)1. Vacuum leaks:

PCV hoses

Intake manifold

Throttle body

Brake booster line
2. Lean mixture causing misfire
HighHighRough idle
(Black smoke from exhaust)1. Restricted air filter
2.Faulty SFI systems:

Faulty pressure regulator

Defective ECT sensor

Faulty ECM

Faulty injectors

Faulty throttle position sensor

Faulty MAF meter
