Final Inspection for Maintenance ServiceS7RS0B0206034
WARNING!
When carrying out road tests, select a safe
place where no man or no running vehicle is
seen so as to prevent any accident.

Seats
Check that seat slides smoot hly and locks securely at
any position. Also check that reclining mechanism of
front seat back allows it to be locked at any angle.
Seat Belt
Inspect belt system including webbing, buckles, latch
plates, retractors and anchors for damage or wear.
Check that seat belt is securely locked. If “REPLACE
BELT” label on seat belt is visible, replace belt.
Battery Electrolyte Level Check
Check that the electrolyte le vel of all battery cells is
between the upper and lower level lines on the case. If
battery is equipped with built-in indicator, check battery
condition by the indicator. Accelerator Pedal Operation
Check that pedal operates
smoothly without getting
caught or interfered by any other part.
Engine Start
Check engine start for readiness.
WARNING!
Before performing th e following check, be
sure to have enough room around the
vehicle. Then, firmly apply both the parking
brake and the regular brakes. Do not use the
accelerator pedal. If the engine starts, be
ready to turn off the ignition promptly. Take
these precautions because the vehicle could
move without warning and possibly cause
personal injury or property damage.

On automatic transaxle vehicles, try to start the engine in
each select lever position. The starting motor should
crank only in “P” (Park) or “N” (Neutral).
On manual transaxle vehicles, place the shift lever in
“Neutral,” depress clutch pedal fully and try to start.
On Automated Manual Transaxl e vehicles, try to start
the engine in each select le ver position. The starting
motor should crank only when select lever is in “N”
(Neutral) and brake pedal is depressed.
Exhaust System Check
Check for leakage, cracks or loose supports.
Clutch (for Manual Transaxle)
Check for the following.
• Clutch is completely released when depressing clutch pedal,
• No slipping clutch occurs when releasing pedal and accelerating.
• Clutch itself is free fr om any abnormal condition.
Gearshift or Select Lever (Transaxle)
Check gear shift or select lever for smooth shifting to all
positions and for good performance of transaxle in any
position.
With automatic transaxle or Automated Manual
Transaxle equipped vehicle, also check that shift
indicator indicates properly according to which position
select lever is shifted to.
With automatic transaxle equipped vehicle, make sure
that vehicle is at complete stop when shifting select lever
to “P” range position and release all brakes.

Scan Tool DataS7RS0B1104007
As the data values are standard values estimated on the basis of values obtained from the normally operating vehicles
by using a scan tool, use them as re ference values. Even when the vehicle is in good condition, there may be cases
where the checked value does not fall within each specified data range. Therefore, judgment as abnormal should not
be made by checking with these data alone.
Also, conditions that can be checked by the scan tool are those detected by ECM and output from ECM as commands
and there may be cases where the engine or actuator is not operating (in the condition) as indicated by the scan tool.
Be sure to use the timing light to check the ignition timing.
NOTE
• There are two types of OBD system depending on the vehicle specification.
For details, refer to “Precaution on On-Board Diagnostic (OBD) System”.
• With the generic scan tool, only star (*) marked data in the following table can be read.
• When checking the data with the engine running at idle or racing, be sure to shift M/T gear to the neutral position and A/T gear to the “Park” position and pull the parking brake fully. Also, if nothing
or “no load” is indicated, turn O FF A/C (if equipped with A/C), all electric loads, P/S and all the other
necessary switches.

DTC P1603: TCM Trouble Code DetectedS7RS0B1104061
Wiring Diagram
DTC Detecting Condition
When ECM receives a trouble code from TCM, which indicates that some problem occurred in sensor circuits and its
calculated values used for operations such as idle speed control, engine power control, and so on by TCM, ECM sets
DTC P1603. (TCM outputs the trouble code to ECM when TCM can not compute the engine control signal due to
malfunctions of sensor circuits used for gear shift control.) 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 Battery voltage supply circuit check
1) Turn OFF ignition switch.
2) Remove ECM from its br acket with ECM connectors
connected.

Electric Throttle Body Assembly On-Vehicle
Inspection
S7RS0B1306003
WARNING!
Never touch throttle valve with finger while
ignition switch is turned ON and accelerator
pedal is depressed. Otherwise, injury may
result by pinching the finger between throttle
valve and throttle body housing.

CAUTION!
• Do not disassemble electric throttle body assembly.
• Do not expose electric throttle body assembly to excessive shock like a
dropping it. If electric throttle body
assembly has been exposed to excessive
shock, it should be replaced.
• Be careful not to accurate a foreign material (like dust and/ or metallic particle)
to the throttle body housing and/or throttle
valve.
Otherwise, the throttle body assembly is
breaking down by throttle valve accretion.
• Do not apply excessive moving force to throttle valve for thro ttle valve operation
check and/or TP sensor performance
check.
Otherwise, the throttle body assembly is
breaking down by damaging the internal
resinous gear of throttle valve actuator.

NOTE
After replacing electric throttle body
assembly, perform calibration of electric
throttle body assembly referring to “Electric
Throttle Body System Calibration”.

Throttle Valve Visual Check
1) Remove air cleaner outlet hose.
2) Check that there isn’t any foreign matter caught between throttle valve and throttle body housing. If
there is, take it out after removing throttle body
referring to “Electric Th rottle Body Assembly
Removal and Installation in Section 1D” and clean
inside of throttle body thoroughly.
