TIRE PRESSURE MONITORING SYSTEM INITIALIZATION PROCEDURE

id021200204000

―  Tire pressures have been adjusted

―  Tires or wheels have been replaced

―  Tires have been rotated

―  DSC HU/CM replaced

―  DSC HU/CM connector disconnected

―  Battery replaced

―  Negative battery cable is disconnected

Note

•  The tire pressure monitoring system initialization can be performed using two types of procedures.

Using Tire Pressure Monitoring System Set Switch

1.  Park the vehicle on safe, level ground.

2.  Adjust all four tire pressures to the specification while the tires are cold. (See WHEEL AND TIRE SPECIFICATION.)

Caution

•  Cold tires means leaving the vehicle for 1 h or, if the vehicle is driven, do so within 1.6 km {0.99 mile}.

3.  Switch the ignition ON (engine off or on).

4.  Press and hold the tire pressure monitoring system set switch.

5.  Press and hold the tire pressure monitoring system set switch until the tire pressure monitoring system warning light flashes 1 or 2 times and the indicator alarm sounds 1 time.

Note

•  When the tire pressure monitoring system initialization is performed, learning initiates. Learning is completed by driving the vehicle for approx. 20 min.

•  While the tire pressure monitoring system is undergoing learning, its primary functions do not operate.

Using M-MDS

Note

•  When performing the initialization procedure using the M-MDS, there are vehicles in which the mis-use prevention logic becomes ineffective and those which do not depending on the DSC HU/CM specification.

•  The DSC HU/CM specification can be verified by the part number indicated on the label adhered to the DSC HU/CM.

DSC HU/CM part number in which mis-use logic prevention will not become ineffective

―  K011 43 7A0A or B

―  K0Y1 43 7A0A or B

DSC HU/CM part number in which mis-use logic prevention will become ineffective

―  KJ01 43 7A0A or B

―  KJY1 43 7A0A or B

―  K0Y1 43 7A0C

1.  Park the vehicle on safe, level ground.

2.  Adjust all four tire pressures to the specification while the tires are cold. (See WHEEL AND TIRE SPECIFICATION.)

Caution

•  Cold tires means leaving the vehicle for 1 h or, if the vehicle is driven, do so within 1.6 km {0.99 mile}.

3.  Connect the M-MDS (IDS) to DLC-2.

4.  After the vehicle is identified, select the following items from the initial screen of the IDS.

(1)  Select “Chassis”

(2)  Select “ABS/DSC”

(3)  Select “TPMS Reset”

Note

•  When the tire pressure monitoring system initialization is performed, learning initiates. Learning is completed by driving the vehicle for approx. 20 min.

•  While the tire pressure monitoring system is undergoing learning, its primary functions do not operate.
