DTC Troubleshooting
NOTE
• When measuring circuit voltage, resistance and/or pulse signal at ECM connector, connect the
special tool to ECM and/or the ECM connectors re ferring to “Inspection of ECM and Its Circuits”.
• Upon completion of inspection and repair work, perform “DTC Confirmation Procedure” and confirm that the trouble has been corrected.

DTC P2111 / P2112: Throttle Actuator Control System - Stuck Open / ClosedS7RS0B1104070
DTC Detecting Condition and Trouble Area
DTC Confirmation Procedure
1) With ignition switch turned OFF, connect scan tool.
2) Turn ON ignition switch and clear DTC using scan tool.
3) Ignition switch turned OFF for 20 sec. or more.
4) Turn ON ignition switch and check DTC.
Step Action Yes No
1 Was “Engine and Emission Control System Check”
performed? Go to Step 2. Go to “Engine and
Emission Control
System Check”.
2 Throttle actuator cont rol relay circuit check
1) Remove throttle actuator co ntrol relay from individual
circuit fuse box No.1 with ignition switch turned OFF.
2) Check for proper connection to throttle actuator control relay “BLK/RED”, “YEL/BLU”, “BLU/ORN” and “RED/
YEL” wire terminals.
3) Turn ON ignition switch.

Front Wheel Alignment ConstructionS7RS0B2201002
Among factors for front wheel alignment, only toe setting
can be adjusted. Camber and caster are not adjustable.
Therefore, should camber or caster be out of
specification due to the damage caused by hazardous
road conditions or collision, whether the damage is in
body or in suspension should be determined and
damaged body should be repaired or damaged
suspension should be replaced.
Preliminary Checks Prior to Adjustment Front Wheel
Alignment
Steering and vibration complaints are not always the
result of improper wheel alignment. An additional item to
be checked is the possibility of tire lead due to worn or
improperly manufactured tires. “Lead” is the vehicle
deviation from a straight path on a level road without
hand pressure on the steering wheel. Refer to “Radial
Tire Lead / Pull Description in Section 2D” in order to
determine if the vehicle has a tire lead problem. Before
making any adjustment affecting wheel alignment, the
following checks and inspections should be made to
ensure correctness of alignment readings and alignment
adjustments:
• Check all tires for proper inflation pressures and approximately the same tread wear. • Check for loose of ball join
ts. Check tie-rod ends; if
excessive looseness is noted, it must be corrected
before adjusting.
• Check for run-out of wheels and tires.
• Check vehicle trim heights; if it is out of limit and a
correction is needed, it must be done before adjusting
toe.
• Check for loose of suspension control arms.
• Check for loose or missin g stabilizer bar attachments.
• Consideration must be given to excess loads, such as
tool boxes. If this excess load is normally carried in
vehicle, it should remain in vehicle during alignment
checks.
• Consider condition of equipment being used to check alignment and follow manufa cturer’s instructions.
• Regardless of equipment used to check alignment, vehicle must be placed on a level surface.
NOTE
To prevent possible incorrect reading of toe,
camber or caster, vehicle front and rear end
must be moved up and down a few times
before inspection.

Repair Instructions
Front Wheel Alignment Inspection and
Adjustment
S7RS0B2206001
Toe Inspection and Adjustment
Preparation for toe inspection and adjustment.
• Place vehicle in unloaded state on level surface.
• Set steering wheel in straight state.
• Check that inflation pressure of each tire is adjusted properly and wheel is free from deflection.
• Check that each suspension part is free from bend, dent, wear or damage in any other form.
• Check that ground clearance at the right and left is just about the same.
Inspection
Measure toe using toe-in gauge (1).
If toe is out of specified value, adjust it at the tie-rod. Front toe (total) “b”-“a”
: 0 + 1.0 / – 0.5 mm (0 + 0.0394 / – 0.0197 in.)
