NO : Repair the combination meter system (Refer to GROUP 54A, Combination Meter, Troubleshooting, Symptom Procedures − Inspection Procedure 5: The combination meter light does not illuminate normally or the multi information display is not displayed normally). Then go to Step 6.

STEP 5. Check the symptom.

Q: When the "ON/OFF" switch is turned ON, is the "CRUISE" indicator light 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 ECM [Refer to GROUP 13A, Engine Control Module (ECM) ] <2.4L Engine> or [Refer to GROUP 13B, Engine Control Module (ECM) ] <3.0L Engine>. Then go to Step 6.

STEP 6. Check the symptom.

Q: When the "ON/OFF" switch is turned ON, is the "CRUISE" indicator light illuminated?

YES : The procedure is complete.

NO : Return to Step 1.

DATA LIST REFERENCE TABLE

CAUTION

• Driving tests always need two persons: one driver and one observer.
• When shifting the selector lever to "D" range apply the brakes should be applied so that the vehicle does not move forward.

ECM TERMINAL VOLTAGE REFERENCE CHART FOR CRUISE CONTROL SYSTEM OPERATION

Required Special Tool:

• MB992110: Power plant ECU check harness

Use special tool MB992110, check the ECM terminal voltage.

1. Disconnect the all ECM connectors, and connect special tool (MB992110) in between [Refer to GROUP 13A, Engine Control Module (ECM) ] <2.4L Engine> or [Refer to GROUP 13B, Engine Control Module (ECM) ] <3.0L Engine>.

2. Measure the voltages between the check connector terminals of special tool (MB992044) and ground terminals (ECM connector B-11 terminal 81 or 93).

SPECIAL TOOLS

ON-VEHICLE SERVICE

CRUISE CONTROL SYSTEM OPERATION CHECK

CRUISE CONTROL "ON/OFF" SWITCH CHECK

1. Turn the ignition switch to the "ON" position.

2. Check that the "CRUISE" indicator light within the combination meter illuminates when the "ON/OFF" switch is pressed (cruise control system: ON).

3. Press the "ON/OFF" switch again (cruise control system: OFF), and check that the "CRUISE" indicator light within the combination meter goes out.

CRUISE CONTROL SETTING

1. Start the engine.

2. Press the "ON/OFF" switch (cruise control system: ON, "CRUISE" indicator light: illuminated).

3. Drive at the desired speed, above approximately 40 km/h (25 mph).

4. Press the "COAST/SET" switch.

5. Check to be sure that when the "COAST/SET" switch is released the speed is the constant speed.

NOTE: If the vehicle speed decreases to approximately 15 km/h (9 mph) 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 becomes low-speed limit [approximately 40 km/h (25 mph) ] or less, driving at constant speed will be cancelled even if the vehicle speed does not decrease 15 km/h (9 mph) or more.

SPEED-INCREASE SETTING

1. Start the engine.

2. Press the "ON/OFF" switch (cruise control system: ON, "CRUISE" indicator light: illuminated).

3. Set to the desired speed, above approximately 40 km/h (25 mph).

4. Press the "ACC/RES" switch.

5. Check to be sure that acceleration continues while the "ACC/RES" switch is pressed, and that the speed at the time it was released becomes the constant driving speed.

NOTE: Acceleration can be continued even if the vehicle speed has passed the high-speed limit [approximately 160 km/h (100 mph) ]. But the constant driving speed when the "ACC/RES" switch is released will be recorded as the high-speed limit.

SPEED-REDUCTION SETTING

1. Start the engine.

2. Press the "ON/OFF" switch (cruise control system: ON, "CRUISE" indicator light: illuminated).

3. Set to the desired speed, above approximately 40 km/h (25 mph).

4. Press the "COAST/SET" switch.

5. Check to be sure that deceleration continues while the "COAST/SET" switch is pressed, and that the speed at the time it was released becomes the constant driving speed.

NOTE: When the vehicle speed reaches the low limit [approximately 40 km/h (25 mph) ] during deceleration, the cruise control will be cancelled.

RETURN TO THE SET SPEED BEFORE CANCELLATION AND CRUISE CONTROL CANCELLATION

1. Start the engine.

2. Press the "ON/OFF" switch (cruise control system: ON, "CRUISE" indicator light: illuminated).

3. Set to the desired speed, above approximately 40 km/h (25 mph).

4. When any of the following operations are performed while at constant speed during cruise control, check if normal driving is resumed and deceleration occurs.

1. The "CANCEL" switch is pressed.
2. The brake pedal is depressed.

5. At a vehicle speed of approximately 40 km/h (25 mph) or higher, check if when the "ACC/RES" switch is pressed, the vehicle speed returns to the speed before cruise control driving was cancelled, and constant speed driving occurs.

6. When the "ON/OFF" switch is pressed again (cruise control system: OFF) while driving at constant speed, check if normal driving is resumed and deceleration occurs.

CRUISE CONTROL SYSTEM COMPONENT CHECK

CRUISE CONTROL SWITCH CHECK

1. Remove the cruise control switch.

2. Measure the resistance between terminal number 2 and terminal number 3 when each of the "ON/OFF", "CANCEL", "COAST/SET" and "ACC/RES" switches is pressed. If the values measured at the time each switch is pressed correspond to those in the table below, the resistance values are correct.

3. Check that the cruise control switch illuminates when a positive battery terminal is connected to the connector terminal number 4, and terminal number 1 is grounded.

STOPLIGHT SWITCH CHECK

Refer to GROUP 35A, Brake Pedal, Inspection − Stoplight Switch Check.

TRANSMISSION RANGE SWITCH CHECK

Refer to GROUP 23A, On-vehicle Service − Essential Service <2.4L Engine>.

Refer to GROUP 23C, On-vehicle Service − Essential Service <3.0L Engine>.

THROTTLE ACTUATOR CONTROL MOTOR CHECK

Refer to GROUP 13A, On-vehicle Service − Throttle Actuator Control Motor Check <2.4L Engine>.

Refer to GROUP 13B, On-vehicle Service − Throttle Actuator Control Motor Check <3.0L Engine>.
