If the vehicle has both cruise control and VSC, when
replacing ECM, perform VSC recognition as follows:
(a) Turn the ignition switch ON.
(b) After waiting approximately 5 seconds, turn the
cruise control main switch ON.
(c) Keep the cruise control main switch ON for
approximately 5 seconds or more.
HINT:
The VSC recognition will not be reflected in the
cruise control system until the ignition switch is
turned OFF and ON.

TERMINALS OF ECM
1. CHECK ECM
(a) Disconnect the A9 and B30 connectors.
(b) Measure the voltage and resistance of the wire
harness side connectors.
If the result is not as specified, there may be a
malfunction on the wire harness side.

DIAGNOSIS SYSTEM
1. DESCRIPTION
The ECM controls the function of cruise control on this
vehicle. Data of the cruise control or DTC can be read
from the DLC3 of the vehicle. When trouble occurs with
cruise control, check that the CRUISE main indicator
does not come on but DTC inspection is performed.
Therefore, when there seems to be a problem with the
cruise control, use the intelligent tester (with CAN VIM)
or SST to check and troubleshoot it.
2. CHECK DLC3
(a) The ECM uses ISO 15765-4 for communication.
The terminal arrangement of the DLC3 complies
with SAE J1962 and matches the ISO 15765-4
format.
NOTICE:
*: Before measuring the resistance, leave the
vehicle as is for at least 1 minute and do not
operate the ignition switch, other switches or
doors.
If the result is not as specified, the DLC3 may have
a malfunction. Repair or replace the harness and
connector.

HINT:
Connect the cable of the intelligent tester (with CAN
VIM) to the DLC3, turn the ignition switch ON and
attempt to use the tester. If the display indicates that
a communication error has occurred, there is a
problem either with the vehicle or with the tester.
• If communication is normal when the tester is
connected to another vehicle, inspect the DLC3
of the original vehicle.
• If communication is still not possible when the
tester is connected to another vehicle, the
problem may be in the tester itself. Consult the
Service Department listed in the tester's
instruction manual.
3. CHECK INDICATOR
(a) Turn the ignition switch ON.
(b) Check that the CRUISE main indicator light
illuminates when the cruise control main switch is
turned ON, and that the indicator light goes off when
the main switch is turned OFF.
HINT:
• If the indicator check result is not normal,
proceed to troubleshooting for the combination
meter section (see page ME-15).
• If a malfunction occurs in the speed sensor or
stop light switch, etc. during cruise control
driving, the ECM activates the AUTO CANCEL of
the cruise control and the CRUISE main indicator
light blinks to inform the driver of a malfunction.
At the same time, the malfunction is stored in
memory as a diagnostic trouble code.
DTC CHECK / CLEAR
1. CHECK DTC (USING INTELLIGENT TESTER)
(a) Connect the intelligent tester (with CAN VIM) to the
DLC3.
(b) Turn the ignition switch ON.
(c) Read the DTCs by following the directions on the
tester screen.
HINT:
Refer to the intelligent tester operator's manual for
further details.

2. CHECK DTC (USING SST CHECK WIRE)
(a) Using SST, connect terminals 13 (TC) and 4 (CG) of
the DLC3.
SST 09843-18040
(b) Turn the ignition switch ON.
(c) Read the DTC on the CRUISE main indicator light.
HINT:
• If the DTC is not output, inspect the diagnosis
circuit.
• As an example, the blinking patterns of a normal
code and code 52 are shown in the illustration.
3. CLEAR DTC (USING INTELLIGENT TESTER)
(a) Connect the intelligent tester (with CAN VIM) to the
DLC3.
(b) Turn the ignition switch ON.
(c) Read the DTCs by following the directions on the
tester screen.
HINT:
Refer to the intelligent tester operator's manual for
further details.
4. CLEAR DTC (USING SST CHECK WIRE)
(a) Read and record DTCs from the CRUISE main
indicator light. Turn the ignition switch OFF.
(b) If DTCs are indicated, repair the relevant circuits
using the DTC Chart (see page CC-18).

(c) Clear the DTCs according to one of the following
procedures.
• Disconnect the negative (-) battery cable for
more than 1 minute.
• Remove the EFI NO. 1 and ETCS fuses from the
engine room relay block (located inside the
engine compartment) for more than 1 minute.
(d) Recheck for DTCs.

DATA LIST / ACTIVE TEST
1. READ DATA LIST
HINT:
Using the intelligent tester's DATA LIST allows switch,
sensor, actuator and other item values to be read without
removing any parts. Reading the DATA LIST early in
troubleshooting is one way to save time.
(a) Connect the intelligent tester (with CAN VIM) to the
DLC3.
(b) Turn the ignition switch ON.
(c) Read the DATA LIST according to the display on the
tester.
