TROUBLESHOOTING GUIDELINES
GENERAL00-6
TROUBLESHOOTING GUIDELINESM1001008800340
VERIFY THE COMPLAINT
Make sure the customer's complaint and the ser-
vice writer's work order description are under-
stood before starting work.
Make sure you understand the correct operation
of the system. Read the service manual descrip-
tion to verify normal system operation.
Operate the system to see the symptoms. Look
for other symptoms that were not reported by the
customer, or on the work order, that may be
related to the problem.
DETERMINE POSSIBLE CAUSES
Compare the confirmed symptoms to the diagnostic
symptom indexes to find the right diagnosis proce-
dure.
If the confirmed symptoms cannot be found on any
symptom index, determine other possible causes.
Analyze the system diagrams and list all possible
causes for the problem symptoms.
Rank all these possible causes in order of proba-
bility, based on how much of the system they
cover, how likely they are to be the cause, and
how easy they will be to check. Be sure to take
experience into account. Consider the causes of
similar problems seen in the past. The list of
causes should be ranked in order from general to
specific, from most-likely to least-likely, and from
easy-to-check to hard-to-check.
FIND THE PROBLEM
After the symptoms have been confirmed, and prob-
able causes have been identified, the next step is to
make step-by-step checks of the suspected system
components, junctions, and links in logical order.
Use the diagnostic procedures in the service manual
whenever possible. Follow these procedures care-
fully to avoid missing an important step in the diagno-
sis sequence. It might be the skipped step that leads
to the solution of the problem.
If the service manual doesn't have step-by-step pro-
cedures to help diagnose the problem, make a series
of checks based on the ranked list of probable
causes. Troubleshooting checks should be made in
the order that the list of causes was ranked:
general to specific
most-likely to least-likely
easy-to-check to hard-to-check
REPAIR THE PROBLEM
When the step-by-step troubleshooting checks find a
fault, perform the proper repairs. Make sure to fix the
root cause of the problem, not just the symptom. Just
fixing the symptom, without fixing the root cause, will
cause the symptom to eventually return.
VERIFY THE REPAIR
After repairs are made, recheck the operation of the
system to confirm that the problem is eliminated. Be
sure to check the system thoroughly. Sometimes
new problems are revealed after repairs have been
made.

TROUBLESHOOTING CONTENTSM1001013300062
During diagnosis, a DTC code associated with
other system may be set when the ignition
switch is turned on with connector(s) discon-
nected. On completion, confirm all systems
for DTC code(s). If DTC code(s) are set, erase
them all.
When the DIAGNOSTIC TOOL (MUT-III)
detects a diagnostic trouble code, its display
informs users whether a mechanical problem
currently exists (“current trouble”) or whether
it existed before but normal operation has
been restored (“past trouble”). However, if an
MPI, TPMS or SRS airbag-related DTC is set,
“Active DTC/Stored DTC” is not displayed. In
this case, follow the diagnosis procedure for
current trouble.
If a trouble, detected in a CAN communica-
tion-capable system, can be reproduced,
diagnose the CAN bus lines (Refer to GROUP
54C, Can Bus Line Diagnostics Chart
P.54C-15 or P.54C-15).
Troubleshooting of electronic control systems for
which the MUT -III can be used follows the basic out-
line described below. Even in systems for which the
MUT-III cannot be used, part of these systems still
follow this outline.

8. SERVICE DATA REFERENCE TABLE
Inspection items and normal judgment values have
been provided in this chart as reference information.
9. CHECK AT ECU TERMINALS
Terminal numbers for the ECU connectors, inspec-
tion items, and standard values have been provided
in this chart as reference information.
.
TERMINAL VOLTAGE CHECKS
1. Use correct tool to check each pin location on the
ENGINE-ECU Check harnes MB992044 and
measure with voltmeter.
Short-circuiting the positive (+) test probe
between a connector terminal and ground could
damage the vehicle wiring, the sensor, the ECU,
or all three. Use care to prevent this!
2. Insert the correct terminal tool into each of the
ENGINE-ECU check harness connector
terminals, and measure the voltage while referring
to the check chart.
NOTE: Measure voltage with the ECU connectors
connected.
You may find it convenient to pull out the ECU to
make it easier to connect the ENGINE-ECU check
harness.

Checks don't have to be carried out in the order
given in the chart.
3. If voltage readings differ from normal condition
values, check related sensors, actuators, and
wiring. Replace or repair as needed.
4. After repair or replacement, recheck with the
voltmeter to confirm that the repair has corrected
the problem.
.
TERMINAL RESISTANCE AND
CONTINUITY CHECKS
1. Turn the ignition switch to the “LOCK” (OFF)
position.
2. Disconnect the ECU connector.
If resistance and continuity checks are per-
formed on the wrong terminals, damage to the
vehicle wiring, sensors, ECU, and/or ohmmeter
may occur. Use care to prevent this!
3. Measure the resistance and check for continuity
between the terminals of the ENGIN-ECU check
harness MB992044 connector while referring to
the check chart.
NOTE: Checks don't have to be carried out in the
order given in the chart.
4. If the ohmmeter shows any deviation from the
Normal Condition value, check the corresponding
sensor, actuator and related electrical wiring, then
repair or replace.
5. After repair or replacement, recheck with the
ohmmeter to confirm that the repair has corrected
the problem.

HOW TO USE THE INSPECTION PROCEDURESM1001013500066
The causes of many of the problems occurring in electric circuitry are generally the connectors, components,
the ECU, and the harnesses between connectors, in that order. These inspection procedures follow this
order. They first try to discover a problem with a connector or a defective component.

HOW TO USE TROUBLESHOOTING/INSPECTION SERVICE POINTS
GENERAL00-10
CURRENT TROUBLE
Indicates that the trouble is currently present. Carry
out troubleshooting as described in the applicable
inspection procedure.
PAST TROUBLE
Indicates that the trouble is historic, but normal oper-
ation has been restored. Observe the applicable
inspection procedure with particular emphasis on
connector(s) and wiring harness.
HARNESS INSPECTION
Check for an open or short circuit in the harness
between the terminals which were faulty according to
the connector measurements. Carry out this inspec-
tion while referring to GROUP 00E, Harness Con-
nector Inspection P.00E-2. Here, “Check harness
between power supply and terminal xx” also includes
checking for blown fuse. For inspection service
points when there is a blown fuse, refer to "Inspec-
tion Service Points for a Blown Fuse P.00-16."

MEASURES TO TAKE AFTER
REPLACING THE ECU
If the trouble symptoms have not disappeared even
after replacing the ECU, repeat the inspection proce-
dure from the beginning.
CONNECTOR MEASUREMENT SERVICE POINTSM1001013600063
Turn the ignition switch to the "LOCK" (OFF) position when
connecting and disconnecting the connectors. Turn the ignition
switch to "ON" when measuring, unless there are instructions
to the contrary.
IF INSPECTING WITH THE CONNECTOR
CONNECTED
Be sure to use special tool. Never insert a test probe from the
harness side, as this will reduce the waterproof performance
and result in corrosion.
IF INSPECTING WITH THE CONNECTOR
CONNECTED CONNECTORS>
Check by inserting the multi-meter 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 be forced; use
the test probe tool for this purpose.
