(14F) to 50C (122F) and ºHotº is from 50C (122F) to 100C (212F).
1. INSPECT IGNITION COIL AND SPARK TEST
(a) Check the DTCs.
NOTICE:
If a DTC is present, perform troubleshooting in accordance with a procedure for that DTC.
(b) Check that a spark occurs.
(1) Remove the 6 ignition coils (see page 18-7).
(2) Using a spark plug wrench 16 mm, remove the 6 spark plugs.
Torque: 25 NVm (250 kgfVcm, 18 ftVlbf)
(3) Install the spark plugs to each ignition coil, then connect the ignition coil connectors.
(4) Disconnect the 6 fuel injector connectors.
(5) Ground the spark plugs.
(6) Check that the spark plug occurs at each spark plug while the engine is being cranked.
NOTICE:
Be sure to ground the spark plugs when checking.
Replace the ignition coil if physical impact is felt.
Do not crank the engine for more than 2 seconds.
If a spark does not occur, perform the following test.
1 SPARK TEST
NG
2 CHECK CONNECTION OF IGNITION COIL CONNECTOR
NG CONNECT SECURELY
OK
3 REPLACE IT WITH NORMAL IGNITION COIL AND PERFORM SPARK TEST AGAIN
OK REPLACE IGNITION COIL ASSY
(See page 18-7)

4 CHECK POWER SUPPLY TO IGNITION COIL
(a) Turn the ignition switch ON.
(b) Check that there is battery voltage at the ignition coil positive (+) terminal.

ADJUSTMENT
1. INSPECT TIRE (See page 26-5)
2. MEASURE VEHICLE HEIGHT
Vehicle height:
FrontA - B: 120 mm (4.72 in.)
RearD - C: 52 mm (2.05 in.)
Measuring points:
A: Ground clearance of front wheel center
B: Ground clearance of lower suspension arm No. 2 set bolt
center
C: Ground clearance of strut rod set bolt center
D: Ground clearance of rear wheel center
NOTICE:
Before inspecting the wheel alignment, adjust the vehicle
height to the specified value.
HINT:
Bounce the vehicle at the corners up and down to stabilize the
suspension and inspect the vehicle height.
3. INSPECT TOE-IN
Toe-in:
Toe-in
(total)A + B: 0° ± 12' (0° ± 0.2°)
C - D: 0 ± 2 mm (0 ± 0.08 in.)
If the toe-in is not within the specified value, adjust it at the rack
ends.
4. ADJUST TOE-IN
(a) Remove the rack boot set clips.
(b) Loosen the tie rod end lock nuts.
(c) Turn the right and left rack ends by an equal amount to
adjust the toe-in.
HINT:
Try to adjust the toe-in to the center of the specified value.
(d) Make sure that the lengths of the right and left rack ends
are the same.
(e) Torque the tie rod end lock nuts.
Torque: 74 N´m (755 kgf´cm, 55 ft´lbf)
(f) Place the boots on the seats and install the clips.
HINT:
Make sure that the boots are not twisted.
(g) Perform VSC system calibration. (See page 05-471)

(e) Adjust the camber by pushing or pulling the lower side of
the shock absorber in the direction in which the camber
adjustment is required.
(f) Tighten the nuts.
Torque: 210 NVm (2,141 kgfVcm, 155 ftVlbf)
NOTICE:
When installing the nuts, keep the bolts from rotating and
then torque the nut.
(g) Install the front wheel.
Torque: 103 N´m (1,050 kgf´cm, 76 ft´lbf)
(h) Check the camber.
HINT:
Try to adjust the camber to the center of the specified val-
ue.
Adjusting value for the set bolts is 6' to 30' (0.1° to 0.5°).
If the camber is not within the specified valve, estimate how
much additional camber adjustment will be required, and select
the camber adjusting bolt.
NOTICE:
Tighten the adjusting bolt with a new nut.
(i) Do the steps mentioned above again. At step (b), replace
1 or 2 selected bolts.
HINT:
When replacing the 2 bolts, replace 1 bolt for each time.
