(3) When operating an OBD II scan tool (complying
with SAE J1978) or hand-held tester to erase the
codes, the DTCs and freeze frame data will be
erased. (See the OBD II scan tool's instruction book
for operating instructions.)
(c) When not using the OBD II scan tool or hand-held tester:
Clearing the DTCs.
(1) Disconnecting the battery terminal or remove the
EFI and ETCS fuse from engine room J/B for 60 se-
conds or more.
4. DATA LIST
HINT:
According to the DATA LIST displayed by the OBD II scan tool or Hand-held tester, you can read the value
of the switch, sensor, actuator and so on without parts removal. Reading the DATA LIST as a first step of
troubleshooting is one method to shorten labor time.
(a) Warm up the engine.
(b) Turn the ignition switch OFF.
(c) Connect the OBD II scan tool or Hand-held tester to the DLC3.
(d) Turn the ignition switch ON.
(e) Push the ºONº button of OBD ll scan tool or Hand-held tester.
(f) Select the item º/DIAGNOSIS/ENHANCED OBD ll/DATA LIST/ALL (or ATM)º.
(g) According to the display on tester, read the ºDATA LISTº.

Performing the ACTIVE TEST using the Hand-held tester allows the relay, VSV, actuator and so on to oper-
ate without parts removal. Performing the ACTIVE TEST as a first step of troubleshooting is one method
to shorten labor time.
It is possible to display the DATA LIST during the ACTIVE TEST.
(a) Warm up the engine.
(b) Turn the ignition switch OFF.
(c) Connect the Hand-held tester to the DLC3.
(d) Turn the ignition switch ON.

17. RESET MEMORY
CAUTION:
Perform the RESET MEMORY (AT initialization) when replacing the automatic transmission assy, en-
gine assy or the ECM.
NOTICE:
Hand-held tester only
HINT:
The ECM memorizes the condition that the ECT controls the automatic transmission assy and engine assy
according to those characteristics. Therefore, when the automatic transmission assy, engine assy, or ECM
has been replaced, it is necessary to reset the memory so that the ECM can memorize the new information.
Reset procedure is as follows.
(a) Turn the ignition switch off.
(b) Connect the hand-held tester to the DLC3.
(c) Turn the ignition switch to the ON position and push the hand-held tester main switch on.
(d) Select the item ºDIAGNOSIS/ENHANCED OBD IIº.
(e) Perform the reset memory procedure from the ENGINE menu.
CAUTION:
After performing the RESET MEMORY, be sure to perform the ROAD TEST described earlier.

PRE-CHECK
1. DIAGNOSIS SYSTEM
(a) Description
ECM controls the function of cruise control on this vehicle.
Data of the cruise control or DTC can be read from DLC3
of the vehicle. When a trouble occurs on cruise control,
Check CRUISE MAIN indicator does not light up but DTC
inspection is performed.
Therefore when there seems to be a trouble on cruise
control, use hand-held tester or SST to check and trou-
bleshoot it.
(b) Check the DLC3.
The vehicle's ECM uses ISO 9141-2 for communication.
The terminal arrangement of DLC3 complies with SAE
J1962 and matches the ISO 9141-2 format.
Terminal No.Connection/Specified ConditionCondition
4Chassis Ground e Body Ground/1 or lessAlways
13TC e Body Ground/9 - 14 VAlways
HINT:
If your display shows ºUNABLE TO CONNECT TO VEHICLEº
when you have connected the cable of the hand-held tester to
DLC3, turned the ignition switch ON and operated the hand-
held tester, there is a problem on the vehicle side or tool side.
If communication is normal when the tool is connected to
another vehicle, inspect DLC3 on the original vehicle.
If communication is still not possible when the tool is con-
nected to another vehicle, the problem is probably in the
tool itself, so consult the Service Department listed in the
tool's instruction manual.
