DTC CHECK/CLEAR
1. CHECK DTC WITH INTELLIGENT TESTER II
DTCs which are stored in the ECM can be displayed with the
Intelligent Tester II and generic OBD scantool.
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 Intelligent Tester II to the Data Link Connec-
tor 3 (DLC3).
(b) Turn the ignition switch ON.
(c) Enter the following menus: Enter/ Power train/ Engine and ECT/ DTC/ Current (or Pending).
(d) Confirm the DTCs and freeze frame data and then write
them down.
(e) See page 05–245 to confirm the details of the DTCs.
NOTICE:
When simulating a symptom with the scan tool to check the
DTCs, use normal mode. For codes on DIAGNOSTIC
TROUBLE CODE CHART subject to ”2–trip detection log-
ic”, 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 WITH INTELLIGENT TESTER II
(a) Connect the Intelligent Tester II to the DLC3.
(b) Turn the ignition switch ON.
(c) Enter the following menus: Enter/ Power train/ Engine and ECT/ DTC/ Clear.
3. CLEAR DTC WITHOUT INTELLIGENT TESTER II
Disconnecting the battery terminal or remove the EFI and
ETCS fuses from the engine room R/B for 60 seconds or more.
But if you disconnect the battery terminal, you should do the
”INITIALIZE” procedure.

MONITOR DRIVE PATTERN
1. MONITOR DRIVE PATTERN FOR ECT TEST
(a) Perform this drive pattern as one method to simulate the detection conditions of the ECT malfunctions.
(The DTCs may not be detected due the actual driving conditions. And some codes may not be de-
tected through this drive pattern).
HINT:
Preparation for driving

Warm up the engine sufficiently. (Engine coolant temperature is 60
C (140
F) or higher)

Drive the vehicle when the atmospheric temperature is –10
C (14
F) or higher. (Malfunction is not
detected when the atmospheric temperature is –10
C (14
F) or less)
Driving note

Drive the vehicle through all gears.
Stop → 1st → 2nd → 3rd → 4th → 4th (lock–up ON).

Perform engine brake test in the S position.
While driving in the 4(S) position and 4th gear lock–up, shift into the ”–” position and down–shift from
4th to 3rd, 3rd to 2nd, 2nd to 1st.
Check that the engine brake performs properly whenever down–shift takes place.

Repeat the above driving pattern three times or more.
NOTICE:

When using the intelligent tester II, monitor status can be found in the ”Power train / Engine and
ECT / Data List”.

In the event that the drive pattern must be interrupted (possibly due to traffic conditions or other
factors) the drive pattern can be resumed and, in most cases, the monitor can be completed.
CAUTION:
Perform this drive pattern on a level road as much as possible and strictly observe the posted speed
limits and traffic laws while driving.

PRE–CHECK
1. DIAGNOSIS SYSTEM
(a) Description
The ECM stores trouble codes when trouble occurs on
the vehicle.
The diagnosis system allows for reading of the trouble
codes from the DLC3. If the CRUISE main indicator light
does not come on after DTC check, it means a malfunc-
tion has occurred in the cruise control system.
Use the intelligent tester II to check and solve the prob-
lem.
(b) Check the DLC3.
The vehicle’s ECM uses ISO 9141–2 (Euro–OBD)/ISO
14230 (M–OBD) for communication protocol. The termi-
nal arrangement of the DLC3 complies with ISO 15031–3
and matches the ISO 9141–2/ISO 14230 format.

BAT(16) – Body groundBattery positiveAlways11 to 14 V
HINT:
If the display shows ”UNABLE TO CONNECT TO VEHICLE” af-
ter connecting the intelligent tester II to the DLC3 and turning
the ignition to the ON position, there is a problem with either the
vehicle or the tool. (Intelligent tester ll only)
If communication is normal when connecting the tool to
another vehicle, inspect the DLC3 on the original vehicle.
If communication is still not possible when connecting the
tool to another vehicle, it suggests the problem is the
tool’s own. In this case, consult Service Department listed
in the tool’s instruction manual.

(c) Check the indicator.
(1) Turn the ignition switch to the ON position.
(2) Check that the CRUISE main indicator light comeson when the cruise control main switch ON–OFF
button is pushed on, and that the indicator light
goes off when the ON–OFF button is pushed off.
HINT:
If there is a problem with the indicator light, inspect the CRUISE
main indicator light circuit ( see page 05–327).
HINT:
If a malfunction occurs in the vehicle speed sensors, stop lamp
switch assy or other related parts during cruise control driving,
the ECM actuates AUTO CANCEL of the cruise control. Then
the CRUISE main indicator light starts to blink, informing the
driver of the malfunction. At the same time, data of the malfunc-
tion is stored as a diagnostic trouble code (DTC).

(d) Output DTCs using diagnosis check wire. (1) Using SST, create a short–circuit between terminalsTC and CG of the DLC3.
(2) Turn the ignition switch to the ON position.
(3) Read and record DTCs from the CRUISE main indi- cator light on the combination meter. As examples,
refer to the chart below for the blinking patterns of
the normal system code and diagnosis trouble code
21 and 52.
HINT:
If the CRUISE main indicator light does not blink because of any
DTC or in the normal code blinking pattern, inspect the following
circuits.

4. DTC CLEAR
(a) The following methods will erase the DTCs and freeze frame data.
(1) The intelligent tester II can be used to erase the codes.
(2) Disconnecting the battery terminal or EFI No.1 fuse can also erase the codes.
(b) After completing repair, the DTC retained in the memory can be cleared by removing the EFI No.1 fuse
for 1 minute or more with the ignition switch off.
(c) Check that the normal system code is displayed after connecting the fuse.
5. PROBLEM SYMPTOM CONFIRMATION (ROAD TEST)
(a) Inspect the SET function.
(1) Push the ON–OFF button on.
(2) Drive at the required speed (40 km/h (25 mph) or
higher).
(3) Push down the cruise control main switch to SET/
COAST.
(4) After releasing the switch, check that the vehicle
cruises at the set speed.
(b) Inspect the ACC (ACCEL) switch.
(1) Push the ON–OFF button on.
(2) Drive at the required speed (40 km/h (25 mph) or
higher).
(3) Push down the cruise control main switch to SET/
COAST.
(4) Check that vehicle speed increases while the cruise
control main switch is pushed up to RES/ACC, and
that the vehicle cruises at the newly set speed when
the switch is released.
(5) Momentarily push up the cruise control main switch
to RES/ACC and then immediately release it.
Check that vehicle speed increases by approxi-
mately 1.6 km/h (1.0 mph) (Tap–up function).
(c) Inspect the COAST function.
(1) Push the ON–OFF button on.
(2) Drive at the required speed (40 km/h (25 mph) or
higher).
(3) Push down the cruise control main switch to SET/
COAST.
(4) Check that vehicle speed decreases while the
cruise control main switch is pushed down to SET/
COAST, and that the vehicle cruises at the newly
set speed when the switch is released.
(5) Momentarily push down the cruise control main
switch to SET/COAST, and then immediately re-
lease it.
Check that vehicle speed decreases by approxi-
mately 1.6 km/h (1.0 mph) (Tap–down function).
