CHECK BATTERY VOLTAGE
Battery voltage: 11 to 14 V
If voltage is below 11 V, replace the battery before proceeding.
CHECK MIL
(a) Check that the MIL illuminates when turning the ignition
switch ON.
If the MIL does not illuminate, there is a problem in the MIL cir-
cuit (refer to MIL CIRCUIT on page DI±512)
(b) When the engine is started, the MIL should turn off.
ALL READINESS
For this vehicle, using the hand±held tester allows readiness
codes corresponding to all DTCs to be read. When diagnosis
(normal or malfunctioning) has been complete, readiness
codes are set. Enter the following menus: ENHANCED OBD II
/ MONITOR STATUS on the hand±held tester.

DTC CHECK / CLEAR
1. CHECK DTC
DTCs which are stored in the ECM can be displayed with the
hand±held tester or generic OBD II scan tool.
These scan tools can display pending DTCs and current DTCs.
Some DTC aren't stored if the ECM doesn't detect a malfunc-
tion during consecutive driving. However, the detected mal-
function during once driving is stored as pending DTC.
(a) Connect the hand±held tester to the Controller Area Net-
work Vehicle Interface Module (CAN VIM). Then connect
the CAN VIM to the Data Link Connector 3 (DLC3).
(b) Turn the ignition switch ON.
(c) Enter the following menus: DIAGNOSIS / ENHANCED
OBD II / DTC INFO / CURRENT CODES (or PENDING
CODE).
(d) Confirm the DTCs and freeze frame data and then write
them down.
(e) See page DI±573 to confirm the details of the DTCs.
NOTICE:
When simulating a symptom with the scan tool to check for
DTCs, use normal mode. For codes on DIAGNOSTIC
TROUBLE CODE CHART subject to º2±trip detection log-
icº, perform the following actions.
Turn the ignition switch OFF after the symptom is simulated
once. Then repeat the simulation process again. When the
problem has been simulated twice, the MIL illuminates and the
DTCs are recorded in the ECM.
2. CLEAR DTC
(a) Connect the hand±held tester to the CAN VIM. Then con-
nect the CAN VIM to the DLC3.
(b) Turn the ignition switch ON.
(c) Enter the following menus: DIAGNOSIS / ENHANCED
OBD II / DTC INFO / CLEAR CODES and press YES.

CHECK MODE PROCEDURE
DESCRIPTION
Check mode has a higher sensitivity to malfunctions and can
detect malfunctions that normal mode cannot detect. Check
mode can also detect all the malfunctions that normal mode can
detect. In check mode, DTCs are detected with 1±trip detection
logic.
CHECK MODE PROCEDURE
(a) Make sure that the items below are true:
(1) Battery positive voltage 11 V or more
(2) Throttle valve fully closed
(3) Transmission in the P or N position
(4) A/C switched OFF
(b) Turn the ignition switch OFF.
(c) Connect the hand±held tester together with the Controller
Area Network Vehicle Interface Module (CAN VIM) to the
DLC3.
(d) Turn the ignition switch ON.
(e) Enter the following menus: DIAGNOSIS / ENHANCED
OBD II / CHECK MODE.
(f) Change the ECM to check mode. Make sure the MIL
flashes as shown in the illustration.
NOTICE:
All DTCs and freeze frame data recorded will be erased if:
1) the hand±held tester is used to change the ECM from
normal mode to check mode or vice±versa; or 2) during
check mode, the ignition switch is turned from ON to ACC
or LOCK.
Before check mode, make notes of the DTCs and freeze
frame data.
(g) Start the engine. The MIL should turn off after the engine
starts.
(h) Perform ºMONITOR DRIVE PATTERNº for the ECT test
(See page DI±551).
(Or, simulate the conditions of the malfunction described
by the customer).
(i) After simulating the malfunction conditions, use the
hand±held tester diagnosis selector to check the DTC
and freeze frame data.

DIAGNOSIS SYSTEM
1. BUS CHECK
HINT:
The ECUs that are properly connected to the CAN communica-
tion system can be displayed using the hand±held tester via
CAN VIM.
(a) Select ºBUS CHECKº from the ºOBD/MOBD MENUº
screen.
(b) Press ºENTERº on the hand±held tester via CAN VIM.
(c) The screen displays the ECUs and sensors that are prop-
erly connected to the CAN communication system.
HINT:
There is a communication stop in the system of any properly
connected ECUs or sensors that are not displayed
(see page DI±1067).
