Error in Past When Identifying Transmitter
HINT:
- Refer to IDENTIFY TRANSMITTER (ERROR IN PRESENT) if the DTC is output currently. Identify Transmitter (Error In Present) Refer to IDENTIFY TRANSMITTER (ERROR IN PAST) if a previously output DTC is not output now. Even when DTCs C2165/65 to C2169/69 are output both as present and past codes, refer to IDENTIFY TRANSMITTER (ERROR IN PAST).
- 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 procedures must be followed to confirm the ID No. and tire location.
- The following are the procedures to identify which wheel's transmitter ID1 is resulting from when assuming that either of the DTCs C2141/41 (Transmitter ID1 error) or C2165/65 (Abnormal temperature inside ID1 tire) is detected. Identify the corresponding transmitter using the same procedures when DTCs C2142/42 to C2145/45, C2166/66 to C2169/69 are detected.
