DESCRIPTION


DTC No.
DTC Detecting Condition
Trouble Area
C2141/41
C2142/42
C2143/43
C2144/44
If an "ERROR" signal is received 3 times consecutively, the tire pressure monitor valve sub-assembly will be judged as defective and this DTC will be output.
This will happen in situations where the inflation pressure is outside the range 0 to 637.5 kPa (0 to 6.48 kgf/cm2, 0 psi to 92.2 psi), the temperature inside the tire is outside the specified range -40 to 215°C (-40 to 419 °F), or an error occurs in the tire pressure monitor valve sub-assembly or the area.
  1. Tire pressure monitor valve sub-assembly
  2. Tire pressure monitor ECU
  3. Tire pressure monitor receiver assembly

HINT:
It is necessary to perform the procedure to identify the tire pressure monitor valve sub-assembly that is malfunctioning because it cannot be identified by the output DTC.


INSPECTION PROCEDURE

NOTICE:
It is necessary to register an ID code after replacing the tire pressure monitor valve sub-assembly and/or the tire pressure monitor ECU (Click here).

HINT:
Set the tire pressure to the specified value.

1.CHECK TIRE PRESSURE WARNING LIGHT

  1. Check the tire pressure warning light.

    Result:

    Proceed to
    		Condition
    A
    		Does not blink
    B
    		Comes on and goes off repeatedly at 0.5 second intervals



B
Go to step 5

4.CHECK DTC

  1. Check for DTC.

    OK:
    DTC is not output.

    HINT:
    1. If the result is OK, replace the tire pressure monitor valve sub-assembly specified in STEP 2.
    2. Before installing a new tire pressure monitor valve sub-assembly, read and write down its transmitter ID.
    3. Register the transmitter ID after replacement, and then set the tire pressure to the specified value.

Go to step 9
OK

REPLACE TIRE PRESSURE MONITOR VALVE SUB-ASSEMBLY 

5.IDENTIFY TRANSMITTER CORRESPONDING TO RECORDED DTC

NEXT


6.REPLACE TIRE PRESSURE MONITOR VALVE SUB-ASSEMBLY

  1. Replace the identified tire pressure monitor valve sub-assembly with a new one.

    HINT:
    Before installing a new tire pressure monitor valve sub-assembly, read and write down its transmitter ID.


NEXT


7.REGISTRATION OF TRANSMITTER ID

  1. Register the transmitter ID for 4 wheels (Click here).

  1. Set the tire pressure to the specified value.
