REGISTRATION
NOTICE:
S The injector compensation code will be required to register with the ECM when replacing injec-
tors or the ECM.
S If an incorrect injector compensation code was registered with the ECM, it may rattle the engine
assembly or the engine idling may become rough. In addition, it may become a cause of engine
failure or shorten the life of the engine.
1 . If you replace the ECM with a new one, register all the injector compensation codes with the
new ECM as follows:
(a) Prior to replacing the ECM, read all the compensation codes stored in the existing ECM using the hand−held tester, and then write them down (see page 05 −273).
(b) After replacing the ECM, enter the written compensation codes into the ECM using the hand −held tes-
ter (see page 05 −277).
(c) Turn the ignition switch to OFF and turn the hand −held tester OFF, then wait for 30 seconds or more.
(d) Turn the ignition switch to ON and turn the hand −held tester ON, then clear DTC P 160 1using the
hand −held tester (see page 05 −290).
HINT:
SIn order to optimize the injector’s fuel injection characteristic, the ECM compensates the injection dura-
tion by each cylinder. The ECM stores and uses compensating data in the form of a 30 −digit −alphanu-
meric value that is imprinted on the head portion of each injector as the injector compensation code.
SIf you installed a new injector, its own injector compensation code is needed to register with the ECM.
Also, if you replaced the ECM, the compensation codes of all the injectors are needed to register be-
cause the new ECM dose not have the codes until they are registered.
SOnce the ECM is replaced, DTC P 160 1will be present when turning the ignition switch to ON. This
is to inform you that the injector compensation codes are required to register with the ECM. In order
to clear the DTC, register the compensation codes first, then turn the ignition switch to OFF and wait
for 30 seconds or more.

2. SET INJECTOR COMPENSATION CODE
(a) Connect the hand−held tester to the DLC 3.
(b) Turn the ignition switch to ON.
(c) Turn the hand−held tester ON.
NOTICE:
Do not start the engine in this operation.
HINT:
Injector compensation code is imprinted on the head portion of
the injector.

(d) Enter ”DIAGNOSIS / OBD/MOBD / DIAGNOSTIC MENU
ECD” and select the item ”INJECTOR COMP”.
(e) Press the ”ENTER” button on the hand−held tester.
(f) Press the ”Enter” button again.
(g) Select ”SET COMP VALUE” and press the ”ENTER” but-
ton.
(h) Press the ”ENTER” button.
(i) Select a cylinder number which you want to register the
compensation code.
(j) Press the ”ENTER” button.

(k) Input the compensation code (30−digit−alphanumeric
value).
(l) After inputting, press the ”ENTER” button.
(m) Press the ”ENTER” button again.
(n) Confirm the injection compensation code displayed on
the hand−held tester.
NOTICE:
Be careful not to register a wrong compensation code to
the ECM. If a wrong code is set to the ECM, rough idling or
engine rattling may result. In addition, it may become a
cause of engine failure or shorten the life of the engine.
HINT:
SThe code shown in the illustration is an example.
SIf a wrong compensation code was entered on the hand−
held tester, select the ”NO” button to correct the error
(Back to step [g]).
(o) Press the ”YES” button to set the code to the ECM.
(p) Wait until the next screen comes up.

(q) Press the ”NO” button to complete the registration.
HINT:
SIf you want to register other compensation codes for the
other cylinders, press the ”YES” button instead of ”NO”.
SBy pressing the ”NO” button, the hand−held tester returns
to the ”DIAGNOSTIC MENU ECD” screen.
(r) Turn the ignition switch to OFF and wait for 30 seconds
or more.

hand −held tester (see page 05 −290).
2. If you replace the injector with a new one, register its compensation code of the new injector as follows:
(a) Replace an injector.
(b) Read a new injector ’s compensation code which is imprinted on the head portion of the injector.
(c) Enter the compensation code into the ECM using the hand −held tester (see page 05 −277).
(d) Turn the ignition switch to OFF and turn the hand −held tester OFF, then wait for 30 seconds or more.
