GENERAL How to Use Troubleshooting/Inspection Service Points
4.After repair or replacement, recheck the voltmeter to confirm the repair
the problem.
Terminal Resistance and Continuity Checks
1. Turn the ignition switch to off.
2. Disconnect the ECU connector.
3.Measure the resistance and check for continuity bet ween the terminals of the ECU
connector while referring to the check chart.
NOTE
Checks don’t have to be carried out in the order gi ven in the chart.
Cautlon
If resistance and continuity checks are performed the wrong terminals, damage
vehicle wiring, sensors, ECU, and/or ohmmeter may o ccur.
Use care to prevent this!
4.If the ohmmeter shows any deviation from the Normal Condition value, check the corresponding
5.
sensor, actuator and related electrical wiring, then repair or replace.
After repair or replacement, recheck with the ohmme ter to confirm that the repair
the problem.
10. INSPECTION PROCEDURES USING AN OSCILLOSCOPE
When there are inspection procedures using an oscil loscope, these are listed here.

GENERAL How to Use Troubleshooting/Inspection Service ‘Points
CONNECTOR
Turn the ignition switch to when connecting and discon-
necting the connectors, and turn the ignition switch to ON
when measuring if there are no instructions to the contrary.
IF INSPECTING WITH THE CONNECTOR
CONNECTED
(WITH CIRCUIT IN A CONDITION OF
Waterproof Connectors
Be sure to use the special tool (harness connector) . Never
insert a test probe from the. harness side, because to do
so will reduce the waterproof performance and result in corro-
sion.
Ordinary (non-waterproof) Connectors
Check by inserting the test probe from’. the harness side.
Note that if the connector (control unit, etc.) is too small to
permit insertion of the test probe, it should not b e forced;
use a special tool (the extra-thin probe in the har ness set
for checking) for this purpose.
IF INSPECTING WITH THE CONNECTOR DISCONNECTED,

Use the special tool (inspection harness for
pin
contact pressure in the harness set, for ‘inspectio n).
The inspection harness for connector pin contact pr essure’
should be used. The test probe
be forcibly in-
serted, as it may cause a defective contact.
Touch the pin directly with the test bar.
Caution. .
At time, be careful not to short the connector
with the test probes. To do so may damage the
inside the ECU.

GENERAL Precautions before Service . .
Caution
1.Before connecting or disconnecting the negative
be sure to turn off the ignition and
the lighting switch.
(if this is not done, the possibility semi-
conductor parts being damaged.)
2.After completion of the work steps [when the bat-
tery’s negative terminal is connected], warm
up the engine and allow it for approximately
five minutes under the conditions be-
low, in order to stabilize the engine condi-
tions, and then check to be sure that idling’ is
satisfactory.
Engine temperature:
Lights, electric fans, accessories: OFF
Transaxle: Neutral position
(A/T models: “N” or “P”)
Steering
neutral (center) position
mm (in.)
Scan tool
ROM pack
VEHICLE WASHING
If high-pressure car-washing equipment or steam car -washing
equipment is used to wash the vehicle, be maintain
the spray nozzle at a distance of at ‘least 300 mm (12 in.)
from any plastic parts and all opening parts (doors , luggage
compartment, etc.).
APPLYING ANTI-CORROSION
OTHER UNDERCOAT AGENTS.,
Be careful not to adhere oil or grease to the heate d oxygen
sensor. If adhered, the sensor may malfunction.
Protect the heated oxygen sensor with a cover befor e applying
anti-corrosion agent, etc.
SCAN TOOL
To operate the scan tool, refer to the “MUT-II OPER ATING
INSTRUCTIONS”.
Caution
Turn the ignition switch off befoie connecting and discon-
necting the scan tool.

GENERAL Maintenance

5. SPARK PLUGS
1.Spark plugs must spark properly to assure proper engine
performance and reduce exhaust emission
Therefore, they should be periodically with new
ones.
2. The new plugs should be checked gap.

6. IGNITION CABLES (Replace)
The ignition cables should. be replaced periodicall y with new
ones. After replacing, make sure that the ignition cables are
routed properly and fully seated.
NOTE
When disconnecting an ignition cable; be sure to ho ld the
cable boot. If the cable is disconnected by pulling on the
cable alone, an open circuit might result.
7. TIMING BELT (Replace)
00100220027
Replace the belt with a new one periodically to ass ure proper
engine performance.
For disassembly and assembly procedures; Refer to GROUP
Timing Belt.
Refer to GROUP
Timing Belt.
Refer to GROUP 11
Timing Belt.
8. DRIVE BELT (For Generator, Water Pump, Power Steering Pump) (Check condition)
Check the tension of the drive belt. Check the driv e belt
for evidence of cuts and cracks, and replace it if defective.

“SRS” WARNING LIGHT CHECK,
Turn the ignition key to the “ON” position. the
warning light illuminate for about 7 seconds, turn “OFF” and
then remain extinguished for at least 45 seconds? I f yes,
SRS system is functioning properly. If not, refer t o GROUP
Troubleshooting.
SRS COMPONENTS VISUAL CHECK
1.Turn the ignition key to position, disconnect the
negative battery cable and tape the ‘terminal.
Caution
Wait at least 60 seconds
disconnecting the bat-
tery cable before doing any further
The SRS system is designed to enough voltage
to deploy the air bag for a short after the
battery has been disconnected, so serlous
result from unintended air bag deployment
is done on the SRS system immediately the
tery cable is disconnected. ,
2. Remove the floor console assembly. (Refer GROUP
