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.

CHECK AT ENGINE-ECU TERMINAL

M1172002701936

Use special tool power plant ECU check harness
(MB992291), check the engine-ECU terminal volt-
age.
1. Remove the engine-ECU (Refer to GROUP 13A

−

Engine-ECU ).

2. Connect special tool MB992291 between the

engine-ECU and the body-side harness
connector.

3. Measure the voltages between the check

connector terminals of special tool MB992291 and
earth terminals No.116, 117 or 145.

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

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

the cruise control indicator lamp within the
combination meter goes out.

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

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.
