OPERATION
The engine-ECU detects "ON/OFF" switch ON signal 
to illuminate the cruise control indicator lamp on the 
combination meter.

COMMENT
The combination meter or engine-ECU may also be 
defective.

PROBABLE CAUSE

• Damaged harness or connector.

• Malfunction of the combination meter.

• Malfunction of the engine-ECU.

DIAGNOSIS PROCEDURE

STEP 1. Check the cruise control indicator lamp.
(1) Disconnect engine-ECU connector C-105 and 

check at the harness side connector.

(2) Turn the ignition switch to the "ON" position.
(3) Check the illumination condition of the cruise 

control indicator lamp when engine-ECU 
connector C-105 terminal No.45 is earthed.

OK: The cruise control indicator lamp 
illuminates.

Q: Is the check result normal?

YES : 

Go to Step 5.

NO : 

Go to Step 2.

STEP 2. Connectors check: C-111 combination 
meter connector, C-105 engine-ECU connector 
and C-53 <LHD> or C-35 <RHD> intermediate 
connector.

Q: Is the check result normal?

YES : 

Go to Step 3.

NO : 

Repair or replace the damaged connector. 
Then go to Step 6.

STEP 3. Check the harness wire between 
combination meter connector C-111 terminal 
No.53 and engine-ECU connector C-105 terminal 
No.45.

• Check harness wire for open/short circuit and 

damage.

Q: Is the check result normal?

YES : 

Go to Step 4.

NO : 

Repair or replace the damaged harness 
wire. Then go to Step 6.

STEP 4. Check the combination meter.
Refer to GROUP 54A 

− Combination Meter, Trouble-

shooting, Check at ECU Terminals .

Q: Is the check result normal?

YES : 

Go to Step 5.

NO : 

Replace the combination meter (Refer to 
GROUP 54A 

− Combination Meter ). Then 

go to Step 6.

STEP 5. Check the symptom.

Q: When the "ON/OFF" switch is turned ON, is the 

cruise control indicator lamp illuminated?
YES : 

It can be assumed that this malfunction is 

intermittent (Refer to GROUP 00 

− How to 

Use Troubleshooting/Inspection Service 
Points, How to Cope with Intermittent 
Malfunctions ).

NO : 

Replace the engine-ECU (Refer to GROUP 
13A 

− Engine-ECU ). Then go to Step 6.

STEP 6. Check the symptom.

Q: When the "ON/OFF" switch is turned ON, is the 

cruise control indicator lamp illuminated?
YES : 

The procedure is complete.

NO : 

Return to Step 1.

2. Push the "ON/OFF" switch of the cruise control 

switch, and check that the cruise control indicator 
lamp within the combination meter illuminates.

3. Push the "ON/OFF" switch again, and check that

CRUISE CONTROL SETTING

1. Turn the ignition switch to "ON" position.
2. Push the "ON/OFF" switch (cruise control system: 

ON, cruise control indicator lamp: illuminated).

3. Drive at the desired speed within the range of 

approximately 40 

− 200 km/h.

4. Push the "COAST/SET" switch.
5. Check to be sure that when the "COAST/SET" 

switch is released the speed is the desired 
constant speed.

NOTE: If the vehicle speed decreases to approxi-
mately 15 km/h below the set speed because of 
climbing a hill for example, it is normal for the 
cruise control to be cancelled. When the vehicle 
speed is decelerated to the low speed limit 
(approximately 40 km/h) or less, the constant 
speed driving will be cancelled even if the vehicle 
speed is not decelerated 15 km/h or more from 
the set speed.

SPEED-INCREASE SETTING

1. Turn the ignition switch to "ON" position.
2. Push the "ON/OFF" switch (cruise control system: 

ON, cruise control indicator lamp: illuminated).

3. Set to the desired speed within the range of 

approximately 40 

− 200 km/h.

4. Push the "ACC/RES" switch.
5. Check to be sure that acceleration continues 

while the "ACC/RES" switch is pushed, and that 
the speed at the time it was released becomes the 
constant driving speed.
NOTE: When the vehicle speed reaches the high 
speed limit (approximately 200 km/h) during 
acceleration, the vehicle is driven at a constant 
speed of the high speed limit (approximately 200 
km/h).

SPEED-REDUCTION SETTING

1. Turn the ignition switch to "ON" position.
2. Push the "ON/OFF" switch (cruise control system: 

ON, cruise control indicator lamp: illuminated).

3. Set to the desired speed within the range of 

approximately 40 

− 200 km/h.

4. Press the "COAST/SET" switch.
5. Check to be sure that deceleration continues 

while the "COAST/SET" switch is pushed, and 
that the speed at the time it was released 
becomes the constant driving speed.
