HINT:
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.
(e) Push the ºONº button of Hand-held tester.

PROBLEM SYMPTOMS TABLE
If a normal code is displayed during the diagnostic trouble code check although the trouble still occurs, check
the electrical circuits for each symptom in the order given in the charts on the following pages and proceed
to the page given for troubleshooting.
The Matrix Chart is divided into 3 chapters.
Chapter 1: Electronic Circuit Matrix Chart
Chapter 2: On-vehicle Repair Matrix Chart
Chapter 3: Off-vehicle Repair Matrix Chart
If the instruction ºProceed to next circuit inspection shown on matrix chartº is given in the flow chart
for each circuit, proceed to the circuit with the next highest number in the table to continue the check.
If the trouble still occurs even though there are no abnormalities in any of the other circuits, then check
and replace the ECM.

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.

2. USING HAND-HELD TESTER
(a) Hook up the hand-held tester to the DLC3.
(b) Monitor the ECU data by following the prompts on the tes-
ter screen.
HINT:
Hand-held tester has a ºSnapshotº function which records the
monitored data.
Please refer to the hand-held tester operator's manual for fur-
ther details.
3. DTC CLEARANCE
(a) The following actions will erase the DTCs and freeze
frame data.
(1) Operating the hand-held tester to erase the codes
(See the hand-held tester instruction book for oper-
ating instructions.).
(2) Disconnecting the battery terminals or EFI fuse.
(b) After completing repairs, the DTC retained in memory can
be cleared by removing the EFI fuse for 10 seconds or
more with the ignition switch off.
(c) Check that the normal code is displayed after connecting
the fuse.
4. DATA LIST
HINT:
According to the DATA LIST displayed by the 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 of the method to shorten the labor
time.
(a) Connect the hand-held tester to the DLC3.
(b) Turn the ignition switch ON.
(c) According to the display on tester, read the ºDATA LISTº.
