Mitsubishi Outlander: Diagnostic Function

WARNING INDICATOR

When any malfunction occurs in the items related to the CVT system, which are described below, the symbol (A) continues being displayed in the information screen in the multi information display.

Check if the diagnostic trouble code is set when the symbol (A) continues being displayed in the information screen in the multi information display.

NOTE: When the symbol (B) is displayed in the information screen in the multi information display, the transmission fluid temperature is high. (Symbol (B) is turned on when the fluid temperature is approximately 140ºC (284ºF) or higher and turned off automatically when the fluid temperature drops below approximately 137ºC (279ºF).)

ON-BOARD DIAGNOSTICS

The transaxle control module (TCM) monitors its input/output signals (some signals all the time and others under specified conditions). When an irregular signal is initially monitored, the TCM decides that a malfunction has occurred and records the occurrence as a diagnostic trouble code. There are 33 diagnostic items. The diagnostic results can be read with scan tool. Diagnostic trouble codes are kept in memory by direct battery feed. The codes are retained in memory even if the ignition switch is in the "LOCK" (OFF) position. DTCs are not erased even after the battery terminals and the TCM connector are disconnected. In addition, the diagnostic trouble code can also be erased by scan tool.

NOTE: If a sensor is disconnected when the ignition switch is in the "ON" position, a diagnostic trouble code is stored in memory. In this case, erase the DTC using scan tool.

The 33 diagnostic items are displayed in numeric order.

HOW TO INITIALIZE CVT LEARNED VALUE

PURPOSE

After the CVT assembly, engine assembly, and valve body assembly are replaced, their learned value must be initialized. The initialization procedure is as below.

INITIALIZATION PROCEDURE

1. Move the selector lever to the "P" range and turn the ignition switch to the "LOCK" (OFF) position.

Then, connect scan tool to the data link connector.

2. Turn the ignition switch to the "ON" position, and then move the selector lever to the "R" range.

3. Depress the accelerator pedal while depressing the brake pedal. (Engine is not running.) Using the M.U.T.-III, execute the clear DTC function for the CVT-ECU (even if no code is set).

NOTE: Performing initialization of the learned value will also erase the diagnostic trouble code.

LEARNING PROCEDURE FOR CVT HYDRAULIC CONTROL

PURPOSE

After initialization, the TCM does not have any learned value. This may degrade the shifting operation quality. The learning procedure is described below.

FAIL-SAFE FUNCTION/BACKUP FUNCTION

If abnormality occurs in signals from various sensors, switches, or solenoids, this function allows controlling them with the minimum adverse effect to the driving performance. The following shows the fail-safe controls when an abnormal signal is input to TCM from each sensor.

TORQUE CONVERTER STALL TEST

This test measures the maximum engine speed at the time the torque converter stalls with the selector lever in the "D" or "R" position. With this test, the holding abilities of the clutch and brake that are incorporated in the transaxle can be checked.

WARNING For safety, operators must not stand in front of and at the rear of the vehicle during this test.

1. Check the transmission fluid level, transmission fluid temperature, and engine coolant temperature.

NOTE: Use scan tool MB991958 to measure the transmission fluid temperature.

2. Raise the vehicle.

3. Pull the parking brake lever, and then fully depress the brake pedal.

4. Start the engine.

CAUTION

5. Move the selector lever to the "D" range and fully depress the accelerator pedal. Quickly read the maximum engine speed at this time.

Standard value − Stall speed: 2,400 − 2,900 r/min

6. Move the selector lever to the "R" range, and then repeat the previous step.

Standard value − Stall speed: 2,400 − 2,900 r/min

JUDGMENT OF TORQUE CONVERTER STALL TEST RESULTS

1. Stall speed is high when selector lever is in both "D" and "R" ranges.

2. Stall speed is high only when selector lever is in the "D" range.

3. Stall speed is high only when the selector lever is in the "R" range.

4. Stall speed is low when selector lever is in both "D" and "R" ranges.

HYDRAULIC PRESSURE TEST

CAUTION The transmission fluid temperature should be between 70 − 80ºC (158 − 176ºF) during the test.

1. Check the transmission fluid level and temperature. Check engine coolant temperature.

2. Raise the vehicle so that the wheels are free to turn.

3. Connect the special tools (3.0 MPa (427 psi) oil pressure gauge [MD998330] and joint [MD998331, MB992127] ) to each pressure discharge port.

NOTE:
DR: Torque converter output pressure port
PRI: Primary pressure port
PL: Line pressure port
FWD: Forward clutch pressure port
REV: Reverse brake pressure port

4. Restart the engine.

5. Check that there are no leaks around the special tool port adapters.

WARNING For safety, operators must not stand in front of and at the rear of the vehicle during this test.

6. Measure the hydraulic pressure at each port under the conditions given in the standard hydraulic pressure table, and check that the measured values are within the standard value ranges.

7. If the pressure is not within the standard value, stop the engine and refer to the hydraulic pressure test diagnosis table.

8. Remove the O-ring from the port plug and replace it.

9. Remove the special tool, and install the plugs to the hydraulic pressure ports.

10.Start the engine and check that there are no leaks around the plugs.
