Mitsubishi Outlander: CVT

General Information

F1CJA, W1CJA model has been established.

Mitsubishi Outlander. CVT

TRANSAXLE

The transaxle consists of the torque converter and gear train. The three-element, one-stage, two-phase type torque converter with a built-in torque converter clutch has been adopted. The gear train of F1CJA, W1CJA transaxle consists of 1 set of multi-disc type clutches, 1 set of multi-disc type brakes, and 1 set of planetary gears which are composed of a sun gear, carrier, annulus gear, 2 sets of pulleys and 1 set of steel belts.

ELECTRONICALLY-CONTROLLED SYSTEM

INVECS-III CONTROL

INVECS-III has been newly developed based on INVECS-II utilizing continuous variable characteristics of CVT.

Mitsubishi Outlander. CVT

To select the pulley ratio which can provide the driving force corresponding to the driver's intention and vehicle conditions, TCM selects the optimal pulley ratio and determines the shift strategy to obtain it by detecting the vehicle driving conditions such as the vehicle speed, accelerator angle. Then, it outputs the command to the stepper motor, controls in/out flow of the line pressure to/from the primary pulley, positions the movable pulley of the primary pulley, and controls the gear ratio.

ENGINE BRAKE FEATURE ON THE DESCENDING SLOPE

Pulley ratio is controlled to obtain the engine brake suitable for the driver's feelings.

Engine brake learning feature on the descending slope

Mitsubishi Outlander. CVT

Learning compensation is made to meet the tastes of a driver by judging the amount of the engine brake from the application of the accelerator or the brake.

DRIVING FEATURE ON THE ASCENDING SLOPE

Mitsubishi Outlander. CVT

If the foot leaves the accelerator pedal during driving on the ascending slope (called lift foot), driving capability is secured by preventing excessive upshifting.

Learning feature corresponding to tastes and habits of drivers

Mitsubishi Outlander. CVT

Ratio patterns are continuously switched according to the driving method of a driver.

RATIO PATTERN

<D RANGE>

The shift change is performed in the entire shift range from the lowest to the highest pulley ratio.

<SPORT MODE>

Mitsubishi Outlander. CVT

When the sport mode is switched ON with the selector lever or paddle shift, the fixed shifting line is determined. The upshift/downshift operation enables to shift in steps according to the predetermined shifting line, providing M/T-like shifting. The 6-speed transmission which is suitable for sporty driving is adopted.

DIRECT CONTROL (TORQUE CONVERTER CLUTCH CONTROL)

Mitsubishi Outlander. CVT

By carefully controlling the direct operating pressure depending on the driving conditions, the shock-free direct operation from low speed has been achieved.

Diagnosis

DIAGNOSTIC TROUBLESHOOTING FLOW

Mitsubishi Outlander. CVT

INTRODUCTION TO CVT DIAGNOSIS

The CVT can exhibit any of the following symptoms: noise or vibration is generated, Transmission fluid leaks, the vehicle does not move forward or backward.

The causes of these symptoms could come from: Incorrect mounting, the Transmission fluid may be low, or a component of the transaxle may be faulty.

The following items are suspected as causes for the INVECS-III troubles: malfunction of the TCM, the sensors, the switches, the harness or connectors.

CVT DIAGNOSTIC TROUBLESHOOTING STRATEGY

Use these steps to plan your diagnostic strategy. If you follow them carefully, you will find most CVT malfunctions.

1. Gather as much information as possible about the complaint from the customer.

2. Verify that the condition described by the customer exists.

3. Check the vehicle for any CVT Diagnostic Trouble Codes (DTCs).

4. If you can not verify the condition and there are no DTCs, the malfunction is intermittent. For information on how to cope with intermittent malfunctions, refer to GROUP 00, How to Use Troubleshooting/Inspection Service Points − How to Cope with Intermittent Malfunction.

5. If you can verify the condition but there are no DTCs, or the system can not communicate with scan tool, refer to the Symptom Chart.

6. If there is a DTC, record the number of the code, then erase the code from memory using scan tool.

7. Reconfirm the symptom with a Road Test.

8. If a DTC is set again, go to the Inspection Chart for Diagnostic Trouble Codes.

9. If a DTC is not set again, the malfunction is intermittent. For information on how to cope with intermittent malfunctions, refer to GROUP 00, How to Use Troubleshooting/Inspection Service Points − How to Cope with Intermittent Malfunction.

10.After repairs are completed, conduct a Road Test duplicating the complaint conditions to confirm the malfunction has been eliminated.
