HOW TO DIAGNOSE
L;The most important point in troubleshooting is to determine “Probable Causes”. Once the probable causes
are determined, parts to be checked can be limited to those associated with such probable causes. Thereforeunnecessary checks can be eliminated. The determination of the probable causes must be based
ona theory and be supported by facts and must not be based on intuition only.
TROUBLESHOOTING STEPSIf 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
and making incorrect repairs. The four steps below should be followed in troubleshooting.
I i
,;zirvation of Problem Symp-Determination of Probable
CausesI
Observe the symptom carefully.
Check if there are also other problems.
In determining the probable causes, it is necessary to check
the wiring diagram to understand the circuit as a system.
Knowledge of switches, relays and other parts is necessary
for accurate determination. The causes of similar problems
in the past must be taken into account.
After the problems are corrected, be sure to check that
the system operates correctly. Also, check that new prob-
lems have not been caused by the repair.
INFORMATION FOR DIAGNOSIS
Troubleshooting is carriedout by making step by step

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. The information
is compiled 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 drawings of voltage flow when the switch is operated and
how the component operates in reaction.
(4) Troubleshooting hints include numerous examples of problems which might occur, traced backwardin 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 MFI, 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.
