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):
IIgnition 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.
ICranking
The glow relay turns ON, allowing current to flow through glow
plug.
IStarting
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
IThe 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.
IThis 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.

Number Item Description
q1Power conditionIThis shows the condition when the system receives battery positive voltage (can
be operated).
q2Fusible linkIThe double line shows that this is a fusible link.
IThe open circle shows current flow in, and the shaded circle shows current flow
out.
q3Fusible link/fuse locationIThis 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).
q4FuseIThe single line shows that this is a fuse.
IThe open circle shows current flow in, and the shaded circle shows current flow
out.
q5Current ratingIThis shows the current rating of the fusible link or fuse.
q6ConnectorsIThis shows that connector
E3is female and connectorM1is male.
IThe G/R wire is located in the 1A terminal of both connectors.
ITerminal number with an alphabet (1A, 5B, etc.) indicates that the connector is
SMJ connector. Refer to GI-18.
q7Optional spliceIThe open circle shows that the splice is optional depending on vehicle application.
q8SpliceIThe shaded circle shows that the splice is always on the vehicle.
q9Page crossingIThis arrow shows that the circuit continues to an adjacent page.
IThe A will match with the A on the preceding or next page.
q10Common connectorIThe dotted lines between terminals show that these terminals are part of the same
connector.
q11Option abbreviationIThis shows that the circuit is optional depending on vehicle application.
q12RelayIThis shows an internal representation of the relay. For details, refer to EL section
(ªSTANDARDIZED RELAYº).
q13ConnectorsIThis shows that the connector is connected to the body or a terminal with bolt or
nut.
q14Wire colorIThis 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 descriptionIThis shows a description of the option abbreviation used on the page.
q16SwitchIThis shows that continuity exists between terminals 1 and 2 when the switch is in
the A position. Continuity exists between terminals 1 and 3 when the switch is in
the B position.
q17Assembly partsIConnector terminal in component shows that it is a harness incorporated assem-
bly.
q18Cell codeIThis identifies each page of the wiring diagram by section, system and wiring dia-
gram page number.

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.
