(k) Input the 30±digit±alphanumeric code with the hand±
held tester to register the compensation code to the ECM.
NOTICE:
Be careful not to register a wrong compensation code to
the ECM. The compensation code which stored in the ECM
must be consistent with the compensation code of the in-
jector assembly. If a wrong code was set to the ECM, rough
idling or engine rattling may result. In addition, it may be a
cause of the engine failure or short±life.
(l) After inputting, press the ºENTERº button.
(m) Press the ºENTERº button again.
(n) Confirm the injection compensation code which is dis-
played on the hand±held tester.
HINT:
The code shown in the illustration is an example.
NOTICE:

Make sure the correct compensation code is entered
on the hand±held tester before pressing YES button.

If a wrong compensation code was entered on the
hand±held tester, select the ºNOº button to correct
the error (Back to step (g)).
(o) Press the ºYESº button to set the code to the ECM.
(p) Wait until the next screen comes up.

HINT:

If you want to register other compensation code for other
cylinders, press the ºYESº button instead of ºNO.º

By pressing the ºNOº button, the hand±held tester returns
to the ºDIAGNOSTIC MENU ECDº screen.
BASIC INSPECTION
When the malfunction is not confirmed in the DTC check, troubleshooting shou\
ld be carried out in all the
possible circuits considered as causes of the problem. In many cases, by carrying out the basic engine check
shown in the following flow chart, the location causing the problem can be found quickly and efficiently.
Therefore, using this check is essential in the engine troubleshooting.
1CHECK BATTERY VOLTAGE
NOTICE:
Carry out this check with the engine stopped and ignition switch OFF.
OKNG
Voltage11 V or moreLess than 11 V
NGCHARGE OR REPLACE BATTERY
OK
2CHECK IF ENGINE WILL CRANK

3 CHECK AIR FILTER
(a) Visually check that the air filter is not excessively dirty or oily.
NOTICE:
If necessary, clean the filter with compressed air. First blow
from the inside thoroughly, then blow from the outside of
the filter.
NG CLEAN OR REPLACE
OK

PRECAUTION
1. Since each injector has a characteristic fuel injecting behavior, the ECM compensates such be-
havior by adjusting an injection time for each injector to optimize the fuel injection volume.
Compensating data for the optimum injection volume, which has converted into a 30±digit±al-
phanumeric value, has been imprinted on a head potion of the injector as the injection com-
pensation code.
2. The injection compensation code will be required to register to the ECM when replacing the in-
jectors or the ECM.
3. If an incorrect injection compensation value was registered to the ECM, the engine assembly
may rattle or the engine idling may be rough. In addition, it may be a cause of the engine failure
or short±life.

RANGE/PERFORMANCE PROBLEM
CIRCUIT DESCRIPTION
Refer to DTC P0115 on page 05±593.
DTC No.DTC Detection ConditionTrouble Area
P0116
When THW greater than ±40 \fC (±40 \fF) and less than 60 \fC
(140 \fF), and THA greater than ±6.7 \fC (20 \fF), and when start-
ing engine, conditions (a) and (b) continue (2 trip detection
logic):
(a)Vehicle speed is changing (Not stable)
(b)THW change is lower than 3 \fC (5.4 \fF) after engine was
started.

Engine coolant temperature sensor

Thermostat
In case that reading value of engine coolant temp. sensor will
not change more than 1 \fC (1.8 \fF) even after repeating 6 trips
(detection logic) of adjusting speed pattern with THW more
than 90 \fC (194 \fF) after engine was started.
INSPECTION PROCEDURE
HINT:

If DTCs ºP0115, P0116, P0117and P0118º are output simultaneously, engine coolant temperature
sensor circuit may be open or short. Perform the troubleshooting of DTC ºP0\
115, P0117 or P0118º first.

Read freeze frame data using \b
 . Freeze frame data records the engine conditions
when a malfunction is detected. When troubleshooting, it is useful for d\
etermining whether the vehicle
was running or stopped, the engine was warmed up or not, the air±fuel ra\
tio was lean or rich, etc. at
the time of the malfunction.
1CHECK OTHER DTC OUTPUT(BESIDES DTC P0116)
(a)Read the DTC using the hand±held tester. Result:

HINT:
If any other codes besides ºP0116º are output, perform the troubleshooting for those DTCs first.
