TIRE PRESSURE WARNING SYSTEM - Error in Present While Identifying Transmitter


INSPECTION PROCEDURE

HINT:
  1. Refer to this section if a DTC is currently output. If a DTC in the range C2165/65 to C2168/68 is output previously and currently or any other DTC was output previously but not currently, refer to "Error in Past When Identifying Transmitter".
  2. DTCs relevant to the transmitters are corresponding to each transmitter ID. It is impossible to identify which tire is malfunctioning according to each transmitter ID. Therefore the following procedure must be done to confirm the ID No. and tire location.
1.SET THE PRESSURE OF 4 TIRES TO THE SPECIFIED VALUE
