DIAGNOSTICS - CRUISE CONTROL SYSTEM
056BJ-06
PRE-CHECK
1. DIAGNOSIS SYSTEM
(a) Description
ECM controls of the cruise control the function on a ve-
hicle.
Data stored in the cruise control memory and on the DTC
can be read from the DLC3 on the vehicle. If CRUISE
MAIN indicator light does not come on after the DTC
check, there is a malfunction of the cruise control.
Use the hand-held tester or SST to check and solve the
problem.
(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.
DLC3
C52361
Terminal No. Connection/Specified Condition Condition
4 Chassis Ground Body Ground / 1 or less Always
7 Bus Line / Pulse Generation During Communication
16 Battery Positive Body Ground / 9 - 14 V Always
HINT:
If the display shows "UNABLE TO CONNECT TO VEHICLE" af-
ter connecting the hand-held tester to the DLC3 and turning the
ignition ON, there is a problem either with the vehicle or with the
tool.
S If communication is normal when connecting the tool to
another vehicle, inspect the DLC3 on the original vehicle.
S If communication is still not possible when connecting the
tool to another vehicle, the problem is probably in the tool
itself. Consult the Service Department listed in the tool's
instruction manual.

DIAGNOSTICS - CRUISE CONTROL SYSTEM
CRUISE MAIN Indicator Light (c) Check the indicator.
(1) Turn the ignition switch ON.
(2) Check that the CRUISE MAIN indicator light comes
on when the main switch button is turned ON, and
that the indicator light goes off when the main switch
is turned OFF.
HINT:
If there is a problem with the indicator, inspect the cruise main
I34744 indicator lamp circuit (See page 05-1981 ).
(d) Check the DTC.

CRUISE MAIN indicator light will start to blink, informing the
driver of a malfunction. At the same time, data of the malfunc-
OFF tion is stored as a diagnostic trouble code, or DTC.

2. USING HAND-HELD TESTER
(a) Connect the hand-held tester to DLC3.
(b) Monitor the ECU data by following the prompts on the tester screen.
HINT:
Hand-held tester has a "Snapshot" function which records the monitored data.
Refer to the hand-held tester operator's manual for further details.
3. DATA LIST
HINT:
From the DATA LIST displayed on the the hand-held tester, you can read the value of the switch, the sensor
and so on without removing parts. Reading the DATA LIST as the first step to troubleshooting is one way
to shorten labor time.
(a) Connect the hand-held tester to DLC3.
(b) Turn the ignition switch ON.
(c) According to the display on the tester, read the "DATA LIST".

fuse for 1 minute or more with the ignition switch OFF.
(c) Check that the normal code is displayed after connecting the fuse.
