(c)Check the indicator.
(1)Turn the ignition switch to the ON position.
(2)Check that the CRUISE MAIN indicator light comeson when the main switch is ON, and that the indica-
tor light goes off when the main switch is OFF.
HINT:
If there is a problem with the indicator, inspect the cruise main
indicator light circuit (See page 05±1722).
(d)Check the DTC.
HINT:
If a malfunction occurs in the vehicle speed sensors or stop
lamp switch assy, etc. during cruise control driving, the ECU ac-
tuates AUTO CANCEL of the cruise control and then the
CRUISE MAIN indicator light will start to blink, informing the
driver of a malfunction. At the same time, data of the malfunc-
tion is stored as a diagnostic trouble code, or DTC.
(e)Output of the DTC using diagnosis check wire. (1)Using SST, connect terminals TC and CG
of DLC3.
SST09843±18040
(2)Turn the ignition switch to the ON position.
(3)Read the DTC on the CRUISE MAIN indicator light.
HINT:
If the DTC is not output, inspect the cruise main indicator light
circuit (See page 05±1722) and diagnosis circuit (See page
05±1729).
For example, the normal blinking pattern and the blinking pat-
tern for code 52 are shown in the illustration.

4. DTC CLEAR
(a) The following methods will erase the DTCs and freeze frame data.
(1) The hand±held tester can be used to erase the codes.
(2) Disconnecting the battery terminals or EFI No.1 fuse can also erase the codes (1AZ±FSE).
Disconnecting the battery terminals or EFI the fuse (1CD±FTV).
(b) After completing repairs, 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 to the OFF position.
(c) Check that the normal code is displayed after connecting the fuse.
5. PROBLEM SYMPTOM CONFIRMATION (ROAD TEST)
(a) Inspect the SET switch.
(1) Push the main switch button to ON.
(2) Drive at a desired speed (40 km/h (25 mph) or high-
er).
(3) Push down the control switch to the SET/COAST
position.
(4) After releasing the switch, check that the vehicle
cruises at the desired speed.
(b) Inspect the 'ACC' switch.
(1) Push the main switch button to ON.
(2) Drive at a desired speed (40 km/h (25 mph) or high-
er).
(3) Check that the vehicle speed increases when the
control switch is pushed up to RES/ACC, and that
the vehicle cruises at the set speed when the switch
is released.
(4) Push the control switch to RES/ACC, and then im-
mediately release it. Check that the vehicle speed
increases by about 1.6 km/h (Tap±up function).
