NOTICE:
The ¯ow chart indicates work procedures required to diagnose
problems effectively. Observe the following instructions before
diagnosing.
1) Use the ¯ow chart after locating probable causes of a prob-
lem following the ``Preliminary Check'', the ``Symptom
Chart'' or the ``Work Flow''.
2) After repairs, re-check that the problem has been com-
pletely eliminated.
3) Refer to Component Parts and Harness Connector Loca-
tion for the Systems described in each section for
identi®cation/location of components and harness con-
nectors.
4) Refer to the Circuit Diagram for Quick Pinpoint Check.
If you must check circuit continuity between harness con-
nectors in more detail, such as when a sub-harness is
used, refer to Wiring Diagram in each individual section
and Harness Layout in EL section for identi®cation of har-
ness connectors.
5) When checking circuit continuity, ignition switch should
be ``OFF''.
6) Before checking voltage at connectors, check battery volt-
age.
7) After accomplishing the Diagnostic Procedures and Elec-
trical Components Inspection, make sure that all harness
connectors are reconnected as they were.

Work and diagnostic procedure
Start to diagnose a problem using procedures indicated in
enclosed blocks, as shown in the following example.
CHECK POWER SUPPLY.
1) Turn ignition switch ``ON''.
2) Check voltage between terminal
V1and ground.
Battery voltage should exist.
bCheck item being performed.

measurement results
Measurement results
Required results are indicated in bold type in the correspond-
ing block, as shown below:
These have the following meanings:
Battery voltage®11 - 14V or approximately 12V
Voltage: Approximately 0V®Less than 1V
Cross reference of work symbols in the text and
illustrations
Illustrations are provided as visual aids for work procedures.
For example, symbol
indicated in the left upper portion of
each illustration corresponds with the symbol in the ¯ow chart
for easy identi®cation. More precisely, the procedure under the
``CHECK POWER SUPPLY'' outlined previously is indicated by
illustration
.
Symbols used in illustrations
Symbols included in illustrations refer to measurements or pro-
cedures. Before diagnosing a problem, familiarize yourself with
each symbol.

For details regarding the terminal
arrangement, refer to the foldout page.Check after engine is warmed up suffi-
ciently.
Voltage should be measured with a volt-
meter.
Circuit resistance should be measured
with an ohmmeter.
Current should be measured with an
ammeter.

Lithium Battery Replacement
CONSULT contains a lithium battery. When replacing the battery obey the following:
WARNING:
Replace the lithium battery with SANYO Electric Co., Ltd., CR2032 only. Use of another battery may
present a risk of ®re or explosion. The battery may present a ®re or chemical burn hazard if mistreated.
Do not recharge, disassemble of dispose of in ®re.
Keep the battery out of reach of children and discard used battery conforming to the local regulations.
