I The open circle shows current flow in, and the shaded circle shows current flow
out.
q3Fusible link/fuse location I
This shows the location of the fusible link or fuse in the fusible link or fuse box.
For arrangement, refer to EL section (ªPOWER SUPPLY ROUTINGº).
q4Fuse I
The single line shows that this is a fuse.
I The open circle shows current flow in, and the shaded circle shows current flow
out.
q5Current rating IThis shows the current rating of the fusible link or fuse.
q6Connectors I
This shows that connector
E3is female and connectorM1is male.
I The G/R wire is located in the 1A terminal of both connectors.
I Terminal number with an alphabet (1A, 5B, etc.) indicates that the connector is
SMJ connector. Refer to GI-18.
q7Optional splice IThe open circle shows that the splice is optional depending on vehicle application.
q8Splice IThe shaded circle shows that the splice is always on the vehicle.
q9Page crossing I
This arrow shows that the circuit continues to an adjacent page.
I The A will match with the A on the preceding or next page.
q10Common connector I
The dotted lines between terminals show that these terminals are part of the same
connector.
q11Option abbreviation IThis shows that the circuit is optional depending on vehicle application.
q12Relay I
This shows an internal representation of the relay. For details, refer to EL section
(ªSTANDARDIZED RELAYº).
q13Connectors I
This shows that the connector is connected to the body or a terminal with bolt or
nut.
q14Wire color I
This shows a code for the color of the wire.
B = Black BR = Brown
W = White OR = Orange
R = Red P = Pink
G = Green PU = Purple
L = Blue GY = Gray
Y = Yellow SB = Sky Blue
LG = Light Green CH = Dark Brown
DG = Dark Green
When the wire color is striped, the base color is given first, followed by the stripe
color as shown below:
Example: L/W = Blue with White Stripe
q15Option description IThis shows a description of the option abbreviation used on the page.

When engine coolant temperature is more than approximately 75ÉC
(167ÉF), the glow relay turns off, inactivating the quick-glow control
until coolant temperature drops below approximately 55ÉC (131ÉF).
When coolant temperature is lower than approximately 75ÉC
(167ÉF):
I
Ignition switch ON
After ignition switch has turned to ON, the glow relay turns ON
for a certain period of time in relation to engine coolant
temperature, allowing current to flow through glow plug.
I Cranking
The glow relay turns ON, allowing current to flow through glow
plug.
I Starting
After engine has started, current continues to flow through glow
plug (after-glow mode) for a certain period in relation to engine
coolant temperature.
When engine speed exceeds approximately 4,800 rpm, current
flow through glow plug is interrupted.
The glow indicator lamp turns ON for a certain period of time in
relation to engine coolant temperature at the time glow relay is
turned ON.
COMPONENT DESCRIPTION
Glow plug
I The glow plug is provided with a ceramic heating element to
obtain a high-temperature resistance. It glows in response to a
signal sent from the ECM, allowing current to flow through the
glow plug via the glow relay.
I This engine uses two types of glow plugs.
Type A has a blue or yellow paint mark.
Type B has no paint mark.
The location of the paint mark is shown in the figure.
WARNING:
Do not use two types of glow plugs at the same time.

HFC-134a (R-134a) Service Tools and
Equipment
It is important to understand that HFC-134a (R-134a) refrigerant, and the specified lubricant which must be
used with HFC-134a (R-134a), must never be mixed with CFC-12 (R-12) refrigerant and/or the CFC-12 (R-12)
lubricant.
This means that separate and non-interchangeable service equipment must be used for handling each type
of refrigerant/lubricant.
To prevent the mixing of refrigerants/lubricants, refrigerant container fittings, service hose fittings, and service
equipment fittings (equipment which handles refrigerant and/or lubricant) are different between CFC-12 (R-12)
and HFC-134a (R-134a).
Adaptors to convert from one size of fitting to another must never be used: refrigerant/lubricant contamination
will occur and compressor failure will result.
