CONTENTS
The preceding page contains the GROUP INDEX
which lists the group title and group number.
PAGE NUMBERS
All page numbers consist of two sets of digits
separated by a dash. The digits preceding the dash
identify the number of the group. The digits follow-
ing the dash represent the consecutive page
number within the group. The page numbers can
be found on the top left or right of each page.
TEXT
Unless otherwise specified, each service procedure
covers all models. Procedures covering specific
models are identified by the model codes, or similar
designation (engine type, transmission type, etc.).
A description of these designations is covered in
this unit under “VEHICLE IDENTIFICATION”.
SERVICE PROCEDURES
The service steps are arranged in numerical order
and attentions to be paid in performing vehicle ser-
vice are described in detail in SERVICE POINTS.
DEFINITION OF TERMS
STANDARD VALUE
Indicates the value used as the standard for judging
the quality of a part or assembly on inspection or the
value to which the part or assembly is corrected and
adjusted. It is given by tolerance.
LIMIT
Shows the standard for judging the quality of a part
or assembly on inspection and means the maximum
or minimum value within which the part or assembly
must be kept functionally or in strength. It is a value
established outside the range of standard value. Installation steps
Indicates incidental operation

Removal steps : The numbers before part names
correspond to numbers in the il-
lustration and indicate the order of
removal.
Disassembly steps : The numbers before part
names correspond to numbers
in the illustration, and indicate
the order of disassembly.
This is provided if installation
cannot be made in the reverse
order of “Removal steps”; omit-
ted if installation in the reverse
order of “Removal steps” is
possible.
.
Reassembly steps : I his IS provided It reassembly
cannot be made in the reverse
order of “Disassembly steps”;
omitted if reassembly in the
reverse order of “Disassembly
steps” is possible.

(7) Indication of shielded cables
A shielded cable used , for example, in an electronic control circuit for prevention of malfunctions that may
otherwise be caused by radio interference is indicated by a solid line sandwiched between dashed lines ( E).
(8) Indication of specification-dependent connectors
With regard to harness connectors, the inter-device and -harness connectors which vary in shape or position on
different vehicle specifications, such as those with rear wipers and turbocharger and those without turbo-
charger, are given a specification-dependent connector identification symbol (lower case alphabet) following the
connector symbol.
Example: A - Ola
Specification - dependent connector identification symbol
a : Vehicles with a manual transmission
b : Vehicles with an automatic transmission
c : Vehicles with a power window
d : Vehicles without a power window
(9) Shapes of connectors
The connector shapes are indicated by simplified symbolic marks. For distinction between male and female
connectors, refer to HOW TO IDENTIFY CONNECTORS.
Refer to Item (8)
The b at the end of the connector symbol
is a specification-dependent connector
identification
symbol and indicates that
the connector is used for vehicles with’
automatic transmission.
