GENERAL -How to Use Troubleshooting/Inspection Service Points00-10
HOW TO USE THE INSPECTION PROCEDURES
The causes of a high frequency of problems occurring in electronic circuitry are generally the connectors,
components, the ECU and the harnesses between connectors, in that order. These inspection procedures
follow this order, and they first try to discover a problem with a connector or a defective component.

mode switch is pressed.

2. Indicates inspection carried out using the
MUT-II.
Indicates the operation and inspection proce-
dures.
Indicates the OK judgement conditions.
3. Detailed inspection procedures (methods)
such as component inspection and circuit
inspection are listed on a separate page, and
are given here for reference.
5. Inspect the contact condition at each connector terminal.
(Refer to Connector Inspection Service Points.)
The connector position can be located in the wiring diagram in the
electrical wiring manual by means of this symbol.
Caution
After carrying out connector inspection, always be sure to
reconnect the connector as it was before.
6. Confirm that there are trouble symptoms. If trouble symptoms have
disappeared, the connector may have been inserted incorrectly and the
trouble symptom may have disappeared during inspection.
If it seems that trouble symptoms still remain, proceed to the next page of
instructions.
7. If trouble symptoms still remain up to this stage, there is a possibility that there is an
open or short circuit in the harness between the connectors, so check the harness.
Alternatively, the cause may be a defective ECU, so try replacing the ECU and check
if the trouble symptom disappears.

The connector position can be located in the wiring diagram in the
electrical wiring manual by means of this symbol.
Indicates operation and inspection procedures, inspection terminals
and inspection conditions.
Indicates the OK judgement conditions.
HARNESS INSPECTION
Check for an open or short circuit in the harness between the terminals which were defective according
to the connector measurements. Carry out this inspection while referring to the electrical wiring manual.
Here, “Check harness between power supply and terminal xx” also includes checking for blown fuses.
For inspection service points when there is a blown fuse, refer to “Inspection Service Points for a Blown
Fuse.”
MEASURES TO TAKE AFTER REPLACING THE ECU
If the trouble symptoms have not disappeared even after replacing the ECU, repeat the inspection procedure
from the beginning.

SPARK PLUG CHECK, CLEANING AND REPLACEMENT
SPARK PLUG GAP CHECK
Caution
1. Do not adjust the gap of the iridium plug.
2. Cleaning of the iridium plug could damage the tip of the electrode. Thus, if the plug must
be cleaned because of soot, etc., use a plug cleaner and clean within a short time of 20 seconds
or less to protect the electrode. Do not use a wire brush, etc.
3. Even when the functions of the iridium plug are normal, the electrode section may be blackened.
However, the adhered carbon has properties that easily burned off compared to the conventional
type, so there is no problem. Check the quality of the spark plug by checking the insulation
resistance.
Check the plug gap, and replace if the checked value is more than the limit value.
Standard value, limit value:
MakerModelStandard value (mm)Limit value (mm)
NGKIGR7A-G0.6 - 0.70.75
DENSOVW22PR-DA70.6 - 0.70.75
SPARK PLUG INSULATION RESISTANCE CHECK
Measure the insulation resistance of the spark plug, and
replace if the measured value is less than the limit value.
Limit value: 1 MΩ
CAMSHAFT POSITION SENSOR CHECK
Refer to GROUP 13A - Troubleshooting.
CRANK ANGLE SENSOR CHECK
Refer to GROUP 13A - Troubleshooting.

NOTE
For information concerning the self-diagnosis codes, refer
to GROUP 13A - Troubleshooting.
