S Freeze frame data
Freeze frame data records the engine conditions when a
malfunction is detected. When troubleshooting, freeze
frame data can help determine if the vehicle was running
or stopped, if the engine was warmed up or not, if the air −
fuel ratio was lean or rich, and other data from the time the
malfunction occurred.
2. CHECK DLC3
(a) The v ehicle’s ECM uses t he I SO 9 1 41− 2( Eur o −OBD)
communication protocol. The terminal arrangement of
the DLC3 complies with ISO 1503 1− 03 and matches the
ISO 9 141− 2 format.

HINT:
Connect the cable of the hand −held tester to the DLC3, turn the
ignition switch to ON and attempt to use the hand −held tester.
If the screen displays UNABLE TO CONNECT TO VEHICLE,
a problem exists in the vehicle side or the tester side.
S If the communication is normal when the tool is connected
to another vehicle, inspect the DLC3 on the original ve-
hicle.
S If the communication is still impossible when the tool is
connected to another vehicle, the problem is probably in
the tester itself, so consult the Service Department listed
in its instruction manual.
3. INSPECT BATTERY VOLTAGE Battery voltage: 11 to14V
If voltage is below 11 V, recharge the battery before proceeding.
4. CHECK CHK ENG
(a) The CHK ENG comes on when the ignition switch is turned to the ON position and the engine is not running.
HINT:
If the CHK ENG is not illuminated, troubleshoot the combination
meter circuit (see page 05 −299).
(b) When the engine is started, the CHK ENG should turn off. If the CHK ENG illuminates again, the diagnosis system
has detected a malfunction or abnormality in the system.

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.
