Wireless Control Module (Wcm) - Lancer: Other Mitsubishi Lancer X рестайлинг

TRANSMITTER

The transmitter button operation allows the system to operate as follows

TRANSMITTER OPERATIONS

CHECK OF FREEZE FRAME DATA

The freeze frame data can be checked by using the scan tool (Refer to HOW TO COPE WITH INTERMITTENT MALFUNCTIONS ).

When detecting fault and storing the DTC, the ECU connected to CAN bus line obtains the data before the determination of the DTC and the data when the DTC is determined, and then stores the ECU status of that time. By analyzing each data from scan tool, the troubleshooting can be performed more efficiently. The displayed items are as the table below.

DISPLAY ITEM LIST

WARNINGS/ALARMS - VEHICLES WITHOUT COLOR LIQUID CRYSTAL DISPLAY

If the TPMS fails or the tire pressure is low, the WCM warns the driver of that state by the TPMS warning light and the multi information display in the combination meter.

JUDGMENT CRITERIA

With the global coding counter value "0," if all the global coding data (vehicle information) are not stored, the WCM determines that a problem has occurred.

PROBABLE CAUSES

1. Malfunction of ETACS-ECU
2. Engine control module malfunction
3. ETACS-ECUs have been interchanged between two vehicles.
4. WCM malfunction
5. External noise interference
6. WCMs have been interchanged between two vehicles.

KEY SET IDENTIFICATION Door service key set (LH), Door service key set (RH) < Vehicles without keyless entry system > NOTE: Key (It can only be used for locking and unlocking, and it cannot start the engine.) Trunk lid service key set < Vehicles without keyless entry system (LANCER) > NOTE: Key (It can only be used for locking and unlocking, and it cannot start the engine.)

Note. When re-registering the key (key ID and keyless ID), all the keys (key ID and keyless ID) registered before must be re-registered because all of them will be erased. After registering the keys, make sure that the engine is started normally with all of the keys registered.

TPMS TRANSMITTER CHECK

Refer to ID codes registration procedure ON-VEHICLE SERVICE .

TPMS TRANSMITTER ID CHECK

Refer to ID codes registration procedure ON-VEHICLE SERVICE .

KEYLESS ENTRY SYSTEM CHECK

Check the keyless entry system as described below. If it does not work, perform troubleshooting. Refer to TROUBLE SYMPTOM CHART .

1. Operate the transmitter to check that the doors and liftgate < LANCER SPORTBACK > can be locked and unlocked.
2. Operate the transmitter to check that the answerback function works in response to doors and liftgate < LANCER SPORTBACK > locking/unlocking.

Note. The hazard answerback setting can be changed using the customization function. Confirm which setting is activated before performing these checks. Refer to CUSTOMIZATION FUNCTION .

CUSTOMIZATION FUNCTION

By operating the ETACS system or MMCS of scan tool MB991958, the following functions can be programmed. The programmed information is held even when the battery is disconnected.

CUSTOMIZATION FUNCTIONS

>> C << TIRE PRESSURE INFLATION/NUT RETIGHTENING

Inflate tire to required pressure, then retorque the valve nut to 8.0 ± 0.5 N.m (71 ± 4 in-lb).
