GENERAL INFORMATION

The is a system that integrates the keyless entry function with which remote operation (opening/closing of all doors, opening of trunk lid < LANCER >, liftgate < LANCER SPORTBACK > and warning function to warn a person who intends to damage the vehicle*) can be performed by operating the lock/unlock/trunk lid button or panic button on the ignition key (transmitter). Also, WCM incorporates the immobilizer function, which prohibits the starting of engine using an unauthorized key, and the tire pressure monitoring system (TPMS), which issues a warning to a driver by illuminating or flashing the warning light if an abnormality to the tire pressure or system is detected. WCM has the following features

  1. The ignition key has an indicator light that enables the driver to check if the signal is transmitted correctly or if the battery in the key is discharged.
  2. Each vehicle is provided with two ignition keys, and up to eight ignition keys can be registered.
  3. Settings of the keyless entry function can be adjusted using a customization function. NOTE: *: Horn sounds, and headlights and taillights flash.

Parts nameFunctional description
Wireless control module (WCM)Controls the keyless entry functions, TPMS functions and starting of the engine by using the following communications. Communications with ETACS-ECU, ECM, ASC-ECU and combination meter via CAN Wire communication with the steering lock unit Wireless communication with the ignition key Wireless communication with the TPMS transmitter
Ignition keyThe ignition key receives signals sent from WCM, certifies the key ID, calculates the key ID, and sends the reply data signal to WCM. The ignition key also sends signals to WCM when the lock/unlock/trunk lid < LANCER > button and panic button on it are operated.
Combination meter (Multi information display, TPMS warning light)Communicates with WCM via CAN. Send ignition switch status. Receives the warning request or warning information from WCM, activates (1) the TPMS warning light. Warning symbol and message is additionally displayed on the Multi information display.
ETACS-ECUCommunicates with WCM via CAN. By the door lock/unlock request, trunk lid open request, or panic alarm request from WCM, ETACS-ECU outputs the lock/unlock signal, trunk lid open signal, or panic alarm signal. When the door lock/unlock signal is output, ETACS-ECU flashes or illuminates the turn signal light and dome light to notify that the lock/unlock operation is performed.
ASC-ECUCommunicates with WCM via CAN. Sends the vehicle speed data.
Engine control module (ECM)Communication with WCM via CAN. Send atmospheric pressure data.
TPMS transmitterMeasure tire pressure directly, then send radio frequency signal to WCM.

"Tire Pressure Sensor ID Registration" METHOD

  1. Select "4tires ID Reg. (Change tire PRS.)" and start the tire pressure sensor ID registration. CAUTION: Register all tire pressure sensor IDs within twenty minutes.
  2. "4 SNSR ID Registration Do you want to start? Note Finish ID Registration within 20 minutes." is displayed. Then, press "OK." 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 WCM. 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 WCM may be faulty, thus replace the WCM. 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." NOTE: The TPMS indicator illuminates for tire pressure alarm.
  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.

"TPMS transmitter check" METHOD

According to the following procedures, identify which registered TPMS transmitter corresponds to which wheel, and check the tire pressure and acceleration value of each TPMS transmitter.

  1. Check the data list "Air Pressure, Tire1, 2, 3, 4" and write down the tire pressure for all wheels. NOTE: The display at this time is the data received most recently.
  2. Perform the following procedures for four wheels in order, identify the wheel by checking the tire pressure of each wheel. Change the pressure of tire for 20 kPa (2.9 psi) or more so that the TPMS transmitter sends the latest sensor data (The tire pressure can either be decreased or increased). Check the data list screen to determine which tire number corresponds to the wheel whose tire pressure has changed. NOTE: It may take approximately one minute that the data of tire pressure change is displayed on the scan tool screen. If the data of tire pressure change is not displayed on the scan tool screen, the most possible cause is that the radio wave sent from the TPMS transmitter cannot be received. In this case, the radio wave may be received by performing the procedures from (1) again after turning the tire to change the TPMS transmitter position. If the tire pressure change is still not displayed on the scan tool screen, the TPMS transmitter in which the ID code is not registered may be installed, or the TPMS transmitter may be faulty. Therefore, perform ID code registration or replace the TPMS transmitter according to the instructions of troubleshooting for DTCs. (At this time, do not register the ID codes or replace the TPMS transmitter.)
  3. Check the tire pressure or acceleration value shown in the screen (if needed).
  4. After checking by the tire pressure change, adjust the checked tire pressure to the proper value.

"Tire Pressure Sensor ID Check" METHOD

  1. Select "Tire Pressure Sensor ID Check".
  2. Check the registered TPMS transmitter IDs on the scan tool screen.

  1. Install the valve to housing as shown in the figure.
  2. Insert the seal washer up to the base of the TPMS transmitter, making sure to secure the valve base with a thumb as shown in the figure. Wipe the seal and threading. CAUTION: Visually check that TPMS transmitter is not deformed or damaged. When installing the TPMS transmitter, be sure the rim, seal valve and nut are clean. Ensure the grommet is located inside the valve hole before installing the nut. While installing the nut, push the TPMS transmitter to maintain the lower lip of the transmitter case is in contact with the rim without clearance. While installing the valve nut, ensure the tool is kept aligned to the valve and the valve hole.
  3. Install the valve, in the valve hole, without modifying the angle of the stem (retain position of delivery). The laser marking should be visible at the operator.
  4. When the valve is completely inserted, maintain the TPMS transmitter in contact with the rim, then screw manually the nut until the contact with the wheel.
  5. While maintaining the TPMS transmitter contact with the rim by applying pressure to the back of the valve, slightly press on the cap to wards the center of the wheel in order to adapt the angle of the valve/TPMS transmitter to the profile of the rim. It is mandatory to guarantee the contact of the housing unit on the rim drop center.
  6. While maintaining the TPMS transmitter and valve in position, screw the nut with a torque wrench. Take care that the wrench socket is correctly inserted on the nut. Specified torque: 8.0 ± 0.5 N.m (71 ± 4 in-lb)

  1. Prepare the tire and fix the rim as usual.
  2. Put the tire on the rim, so that the cross point of the belt with the rim is approximately 20 cm (7.9 inch) away from the valve.
  3. Engage the shoe and make sure that 20 cm (7.9 inch) is maintained between the cross point and the valve. The arrow shows the direction of rotation of the wheel.
  4. Turn the wheel in order to engage all the first side of the tire. NOTE: The standard shoes can pass over the sensor without damaging it.
  5. Put the second side of the tire in position, so that the cross point of the belt with the rim is approximately 20 cm (7.9 inch) away from the valve. The curved arrow shows the direction of rotation of the wheel.
  6. Turn the wheel in order to engage all of the second side of the tire. NOTE: The standard shoes can pass over the sensor without damaging it.

>> C << TIRE PRESSURE INFLATION/NUT RETIGHTENING

CAUTIONAfter tire inflation, retighten the valve nut to 8.0 ± 0.5 N.m (71 ± 4 in-lb). This is necessary, because the TPMS transmitter is secured to the wheel with the valve nut and rubber grommet. The rubber grommet will be depressed by tire pressure or deteriorate over a period of time, which requires the valve nut to be retightened.

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