PRE±CHECK
1. DIAGNOSIS SYSTEM
(a) Check the indicator.
(1) Turn the ignition switch ON.
(2) Check that the CRUISE MAIN indicator light comes
ON 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 trouble-
shooting (See page BE±2) for the combination meter section.
(b) Check the DTC.
HINT:
If a malfunction occurs in the No. 1 vehicle speed sensor or ac-
tuator, etc. during cruise control driving, the ECU actuates
AUTO CANCEL of the cruise control and turns on and off the
CRUISE MAIN indicator light to inform the driver of a malfunc-
tion. At the same time, the malfunction is stored in memory as
a DTC.
(c) Output of DTC using diagnosis check wire.
(1) Turn the ignition switch ON.
(2) Using SST, connect terminals Tc and E
1 of DLC2.
SST 09843±18020
(3) Read the DTC on the CRUISE MAIN indicator light.

5. INPUT SIGNAL CHECK
HINT:
(1) For check No.1 ~ No.3

Turn ignition switch ON.
(2) For check No.4

Jack up the vehicle.

Start the engine.

Shift to D position.
(a) Pull the control switch to SET/COAST or RES/ACC posi-
tion and hold it down or up (1).
(b) Push the main switch ON (2).
(c) Check that the CRUISE MAIN indicator light blinks twice
or 3 times repeatedly after 3 seconds.
(d) Turn the SET/COAST or RES/ACC switch OFF.
(e) Operate each switch as listed in the table below.
(f) Read the blinking pattern of the CRUISE MAIN indicator
light.
(g) After performing the check, turn the main switch OFF.
HINT:
When 2 or more signals are input to the ECU, the lowest num-
bered code will be displayed first.
