TIMING CHAIN MAINTENANCE DISPLAY RESET INDEX

Scheme 4: Description
Scheme 4: Description

If the vehicle equipped with 2.0L turbocharged engine (4B11-T/C) is used for rough driving, like competitive running*, the amount of carbon mixed into the engine oil tends to increase. This can possibly cause the timing chain to gradually elongate. To prevent this, the function or logic monitoring the amount of elongation of the timing chain is integrated into the ECM. When the ECM detects the elongation of the timing chain, the warning is shown on the multi-information display of combination meter as shown in the illustration. This gives the driver the information that a visual check of the elongation of the timing chain is necessary. If this warning is continuously neglected, the timing chain can possibly interfere with the other engine components, resulting in the engine being damaged.

Note. * Competitive running means the engine constantly repeats the cycle of the full opened position of the accelerator pedal and the full closed position of the accelerator pedal (Fully floored and fully released pedal positions).

The ECM stores the timing chain conditions as the learning value when the timing chain is installed. The ECM stores the amount of elongation of the timing chain in the EEPROM as the current learning value, compared with the learning value. The ECM judges that the visual check of the elongation of the timing chain is necessary when the current learning value exceeds the specified value. Thus, use the scan tool MB991958 to always carry out the maintenance of the learning value related to the timing chain that is stored by the ECM after the following service.

ServiceMaintenance items by scan tool MB991958Maintenance purpose
ECM replacementLearned value Read&Save (1) Write learned value (Changed ECU) (1)The purpose is that the initial value regarding the amount of elongation of the timing chain stored by the current ECM is loaded in the scan tool MB991958, and then written into the new ECM. This allows the ECM to appropriately monitor the amount of elongation of the timing chain after the ECM replacement.
Visual check of elongation of timing chainLearned value resetThe purpose is that the initial value stored by the current ECM is initialized after the visual check of the elongation of the timing chain by illuminating the warning lamp, whether or not the timing chain is replaced. This allows the ECM to appropriately monitor the amount of elongation of the timing chain.
Timing chain or engine ASSY replacedLearned value resetThe purpose of this procedure is that the initial learning value stored by the current ECM is initialized when the timing chain or the engine ASSY (the timing chain is also replaced with a new one.) is replaced. This allows the ECM to appropriately monitor the amount of elongation of the timing chain.
Initializing learning value for MFI engineLearned value Read&Save Write learned value (Changed ECU)When learning value for MFI engine is initialized, initial learning value for timing chain elongation is also initialized. Thus, initial learning value for timing chain elongation must be stored before initializing learning value for MFI engine.
(1) The visual check of the elongation of the timing chain must be carried out using the scan tool MB991958 under the following conditions (Refer to TIMING CHAIN ELONGATION VISUAL CHECK ). When the initial value cannot be written into the new ECM because of the ECM malfunction.
(1)The visual check of the elongation of the timing chain must be carried out using the scan tool MB991958 under the following conditions (Refer to TIMING CHAIN ELONGATION VISUAL CHECK ). When the initial value cannot be written into the new ECM because of the ECM malfunction.

TPMS RESET - PROCEDURE 1

Note. If a TPM system tire pressure sensor, receiver, antenna or feeder cable(s) is replaced, the tire pressure sensors must be registered.

The following tools are used to register TPM system

  1. TPMS Magnet (MIT46716) or a strong magnet
  2. Scan Tool (MUT-III Sub Assembly) (MB991958)
  3. Vehicle Communication Interface (V.C.I.) (MB991824)
  4. MUT-III USB Cable (MB991827)
  5. MUT-III Main Harness A (MB991910)
CAUTIONTo prevent damage to Scan Tool (MB991958), always turn ignition switch to OFF position before connecting or disconnecting scan tool.
  1. Connect scan tool to Data Link Connector (DLC). see scheme 6
  2. Turn ignition switch to ON position.
  3. Select "INTERACTIVE DIAGNOSIS" from start-up screen.
  4. Select "SYSTEM SELECT".
  5. Choose "TPMS" from "CHASSIS" tab.
  6. Select "MITSUBISHI".
  7. Select "SPECIAL FUNCTION".
  8. Select "TIRE PRESSURE SENSOR ID REGISTRATION". NOTE: Register all tire pressure sensor ID's within 5 minutes.
  9. Select "5TIRES PRES SNSR ID REGISTRATION (NORMAL SPARE TIRE)" or "4TIRES PRES SNSR ID REGISTRATION (COMPACT SPARE TIRE)" and start tire pressure sensor ID registration.
  10. Emit signal from a tire pressure sensor as follows: Clean tire pressure sensor location on wheel rim. Position TPMS Magnet (MIT46716) or a strong magnet as shown, and hold it there for 5 seconds or more. see scheme 7 The reed switch (incorporated in tire pressure sensor) will activate sensor to send tire pressure sensor ID.
  11. Using scan tool, ensure sensor is activated.
  12. Repeat steps 8 - 10 for all sensor-fitted tires (including spare tire). NOTE: If the spare tire pressure sensor ID cannot be registered, bring the spare tire near one of the road tires. Then register the tire pressure sensor ID. There is no TPMS antenna for the spare tire, so this work helps the road tire TPMS antenna receive signal from the spare tire securely. NOTE: If the spare tire is removed, always reposition valve. see scheme 8 If valve is not positioned as shown, the system may determine the spare tire as a road tire incorrectly.
  13. Check completion of the tire pressure sensor ID registration (display on screen).
  14. After tire pressure sensor ID registration, turn ignition switch to OFF position. Remove scan tool. Ensure warning light does not illuminate or flash.

TPMS RESET - PROCEDURE 2

  1. Connect MUT III scan tool. Turn igntion switch to ON postion. From the "Special Functions" screen, select "Tire Pressure Sensor ID Registration".
  2. Select "4tires ID Reg. (Change tire PRS.)" and start the tire pressure sensor ID registration. NOTE: If the ID code registration is not finished within 20 minutes, all the ID codes registered in the TPMS transmitter before will be erased. For this reason, the ID codes need to be registered again.
  3. Decrease the tire pressure to 174 kPa (25.2 psi) or less by changing 20 kPa (2.9 psi) or more, and register the TPMS transmitter ID code of each wheel to KOS-ECU. NOTE: You can start out the operations from any TPMS transmitter. The tire pressure sensor ID registration has no order. On completion of the TPMS transmitter ID code registration, the TPMS transmitter ID code is displayed on the scan tool screen. Scan tool cannot identify which registered TPMS transmitter is used for each wheel. For this reason, write down the tire number for each wheel when the tire number and ID code is displayed on the scan tool during ID code registration. It may take approximately one minute for the ID code to be displayed on the scan tool screen after the tire pressure is reduced. If the ID code is not displayed, reduce the tire pressure another 20 kPa (2.9 psi) or more. If the ID code is not displayed yet, rotate the tire to displace the TPMS transmitter, and reduce the tire pressure 20 kPa (2.9 psi) or more again. If the ID code cannot be registered for all the four wheels, the KOS-ECU may be faulty, thus replace the KOS-ECU. If the ID code can be registered for one wheel or more, the TPMS transmitter in which the code cannot be registered may be faulty, thus replace that TPMS transmitter.
  4. "4 SNSR ID Registration Completed." is displayed. Then, select "OK".
  5. After one minute or more has passed, correct the tire pressure for all wheels with ignition switch "ON".
  6. Check the data list "Registered ID reception, Tire 1, 2, 3, 4" if "YES" is displayed for each tire. When "NO" is displayed, drive the vehicle for approximately 5 minutes, check the display again. If "NO" is still displayed, register the ID code again.
