Number Item Description
1 Power conditionThis shows the condition when the system receives battery positive voltage (can be
operated).
2 Fusible linkThe double line shows that this is a fusible link.
The open circle shows current flow in, and the shaded circle shows current flow out.
3Fusible link/fuse loca-
tionThis shows the location of the fusible link or fuse in the fusible link or fusebox.For
arrangement, refer to EL-12, “POWER SUPPLY ROUTING”.
4FuseThe single line shows that this is a fuse.
The open circle shows current flow in, and the shaded circle shows current flow out.
5 Current rating This shows the current rating of the fusible link or fuse.
6 ConnectorsThis shows that connector E3 is female and connector M1 is male.
The G/R wire is located in the 1A terminal of both connectors.
Terminal number with an alphabet (1A, 5B, etc.) indicates that the connector is SMJ con-
nector. Refer to GI-20.
7 Optional splice The open circle shows that the splice is optional depending on vehicle application.
8 Splice The shaded circle shows that the splice is always on the vehicle.
9 Page crossingThis arrow shows that the circuit continues to an adjacent page.
The A will match with the A on the preceding or next page.
10 Common connectorThe dotted lines between terminals show that these terminals are part of thesamecon-
nector.
11 Option abbreviation This shows that the circuit is optional depending on vehicle application.
12 RelayThis shows an internal representation of the relay. For details, refer to EL-9, “STAN-
DARDIZED RELAY”.
13 Connectors This shows that the connector is connected to the body or a terminal with bolt or nut.
14 Wire colorThis shows a code for the color of the wire.
B=Black
W = White
R = Red
G = Green
L = Blue
Y = Yellow
LG = Light GreenBR = Brown

15 Option description This shows a description of the option abbreviationused on the page.
16 SwitchThis shows that continuity exists between terminals 1 and 2 when the switchis in the A
position. Continuity exists between terminals 1 and 3 when the switch is inthe B posi-
tion.
17 Assembly parts Connector terminal in component shows that it is a harness incorporated assembly.

CAMSHAFT
Valve Lifter Hole Diameter
●Using inside micrometer, measure diameter of valve lifter hole of
cylinder head.
Calculation of Valve Lifter Clearance
(Valve lifter clearance) = (hole diameter of valve lifter) – (outer diam-
eter of valve lifter).
●When out of specified range, referring to each specification of outer and inner diameter, replace either or
both valve lifter and cylinder head.
Valve ClearanceEBS00LQC
INSPECTION
●The following procedure is applicable when: Components related to camshafts or valves are removed,
installed, or replaced. Drivability concerns (poor starting, poor idling, noise) are caused by valve clearance
aging.
1. Warm up engine, and stop.
2. Remove RH splash cover (integrated with undercover).
3. Remove rocker cover. Refer to EM-29, "
ROCKER COVER" .
4. Turn crankshaft pulley clockwise (viewed from front) to align yel-
low paint with timing indicator.
5. At this point, confirm that both intake and exhaust cam noses on
No. 1 cylinder face outward. (No. 1 cylinder is at TDC of its com-
pression stroke.)
●If not, turn crankshaft pulley more.
NOTE:
Or, valves to be checked when No. 4 cylinder is at TDC of its
compression stroke can be checked first following step 8.
6. Referring to figure, measure valve clearances of valves with × in
table below using a thickness gauge.Standard (Intake and exhaust)
: 30.000 - 30.021 mm (1.1811 - 1.1819 in) dia.
Standard (Intake and exhaust)
: 0.025 - 0.061 mm (0.0010 - 0.0024 in)
