GENERAL How to
The most important point in troubleshooting is to deterimine “Probable Causes”. Once the probable causes
are determined, parts to be checked can be limited to those associated with such ‘probable causes.
Therefore, unnecessary checks can be ‘eliminated. The determination of the probable causes must be
based on a theory and be supported by facts and must not be based on intuition only.
TROUBLESHOOTING STEPS
If an attempt is made to solve a problem without going through correct steps, for troubleshooting, the
problem symptoms could become more complicated, resulting in failure to determine the-causes correctly
Observation of Problem Symptoms
2 Determination of Probable Causes
Checking of Parts Associated with
Repair and Confirmation
I
In determining the probable causes, it is to check
the wiring diagram to understand the circuit system.
Knowledge of switches, relays and other parts is necessary
for accurate determination. The causes of
in the past must be taken into
Troubleshooting is carried out by making step by step checks
until the true cause is found. Always go through the proce-
dures considering what check is to be made where for the
best results.
After the problems are corrected, be sure to check that the
system operates correctly. Also check that new problems
have not been caused by the repair.
INFORMATION FOR DIAGNOSIS
This manual contains the cable diagrams as well as the individual circuit drawings, operational explanations,
and troubleshooting hints for each component required to facilitate the task of troubleshooting.
information is complied in the following manner:
(1) Cable diagrams show the connector positions, etc., on the actual vehicle as well as the harness
path.
(2) Circuit drawings show the configuration of the circuit with all switches in their normal positions.“.
(3) Operational explanations include circuit
of voltage flow when the is ‘operated and
how the component operates in reaction.
(4) Troubleshooting hints include numerous examples of problems which might occur,
in a common-sense manner to the origin of the trouble. Problems whose origins may not be found
in this manner are pursued through the various system circuits.
NOTE
Components of ECI, ETACS, ECS, etc. with ECU do not include 3 and 4 above. For this information,
refer to a manual which includes details of these components.
