A: REMOVAL
1) Disconnect the ground cable from battery.
2) Remove the front pillar lower trim and console
side panel lower RH of passenger's side.
3) Detach the floor mat of passenger's seat.
4) Remove the protect cover.
5) Remove the nuts which hold the ECM to the
bracket.

Install in the reverse order of removal.
CAUTION:
•When replacing the ECM, be careful not to
use the wrong spec. ECM to avoid any damage
on the fuel injection system.
•When replacing the ECM, be careful not to
damage the harnesses and connectors.
•When replacing the ECM, immobilizer system
must be registered. To do so, all ignition keys
and ID cards need to be prepared. Refer to the
“IMMOBILIZER TEACHING OPERATION MANU-
AL”.

Diagnostic Trouble Code (DTC) Detecting Criteria
GENERAL DESCRIPTION
2. COMPONENT DESCRIPTION
The variable valve lift system optimizes the intake valve lift by switching between the low lift cam and the high
lift cam according to the engine RPM. The amount of intake valve lift is varied by controlling the oil switching
solenoid valve duty according to signals from the ECM.
3. ENABLE CONDITIONS
(A) When at low speed (B) When at high speed

(1) Oil switching solenoid valve
Secondary Parameters Enable Conditions
Battery voltage≥ 10.9 V
After engine starting≥ 6 sec.
Engine oil temperature≥ 0°C (0°F)

Diagnostic Trouble Code (DTC) Detecting Criteria
GENERAL DESCRIPTION
4. GENERAL DRIVING CYCLE
Perform the diagnosis continuously 6 seconds after engine start while variable valve lift is being controlled.
5. DIAGNOSTIC METHOD
Abnormality Judgment
Judge as NG when the continuous time is longer than the predetermined time when the following conditions
are established.
Time Needed for Diagnosis:
Low side 0.784 seconds
High side: 3.0 seconds
Malfunction Indicator Light: Illuminates as soon as a malfunction occurs.
Normality Judgment
When the continuous time is more than 3 seconds while the following conditions are established, judge as
OK and clear the NG.
6. DTC CLEAR CONDITION
•When the OK idling cycle is completed 40 times in a row
•When “Clear Memory” is performed
7. MALFUNCTION INDICATOR LIGHT CLEAR CONDITIONS
•When the OK driving cycle is completed 3 times in a row
•When “Clear Memory” is performed
