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/cm 2 , 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. |

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
