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.
