DTC CHECK / CLEAR
NOTICE:
When the diagnosis system is changed from normal
mode to check mode or vice versa, all DTCs and freeze
frame data recorded in normal mode are erased. Before
changing modes, always check and make a note of any
DTCs and freeze frame data.
HINT:
• DTCs which are stored in the ECM can be displayed on
the intelligent tester. The intelligent tester can display
current and pending DTCs.
• Some DTCs are not set if the ECM does not detect the
same malfunction again during a second consecutive
driving cycle. However, such malfunctions, detected on
only one occasion, are stored as pending DTCs.
1. CHECK DTC (Using intelligent tester)
(a) Connect the intelligent tester to the DLC3.
(b) Turn the ignition switch ON.
(c) Turn the tester ON.
(d) Select the following menu items: DIAGNOSIS /
ENHANCED OBD II / DTC INFO / CURRENT
CODES or PENDING CODES.
(e) Check the DTC(s) and freeze frame data, and then
write them down.
(f) Check the details of the DTC(s) (see page ES-56).
2. CLEAR DTC (Using intelligent tester)
(a) Connect the intelligent tester to the DLC3.
(b) Turn the ignition switch ON.
(c) Turn the tester ON.
(d) Select the following menu items: DIAGNOSIS /
ENHANCED OBD II / DTC INFO / CLEAR CODES.
(e) Press the YES button.
3. CLEAR DTC (Without using intelligent tester)
(a) Perform either of the following operations.
(1) Disconnect the cable from the negative (-)
battery terminal for more than 1 minute.
(2) Remove the EFI and ETCS fuses from the
engine room relay block (located inside the
engine compartment) for more than 1 minute.

ON-VEHICLE INSPECTION
HINT:
It is normal for the cooling fan to sometimes rotate when the
ignition switch is turned from ACC to ON.
1. CHECK COOLING FAN OPERATION AT LOW
TEMPERATURES (Below 94
C (201F))
(a) Turn the ignition switch ON with the A/C switch OFF.
(b) Check that the cooling fan stops.
If it does not, check the cooling fan relays and
engine coolant temperature sensor, and then check
for disconnection of the connector or wire breaks
between the cooling fan relay and engine coolant
temperature sensor.
(c) Disconnect the engine coolant temperature sensor
connector.
(d) Check that the cooling fan rotates.
If it does not, check the fuses, cooling fan relays,
ECM and cooling fan, and then check for an open
circuit between the cooling fan relay and engine
coolant temperature sensor.
(e) Reconnect the engine coolant temperature sensor
connector.
2. CHECK COOLING FAN OPERATION AT HIGH
TEMPERATURES (Above 96
C (205F))
(a) Start the engine, and then raise the coolant
temperature to above 96
C (205F).
HINT:
Coolant temperature is the value detected by the
engine coolant temperature sensor on the cylinder
head.
(b) Check that the A/C switch is OFF.
