Identify transmitter (Error in present)
HINT:
Refer to IDENTIFY TRANSMITTER (ERROR IN PRESENT) if the DTC is output currently. 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 TRANS-
MITTER (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.

Using hand–held tester, check the tire pressure data of each wheel.
PREPARATION:
(a)
Connect the hand–held tester to the DLC3.
(b)
Turn the ignition switch to the ON position, and push the hand–held tester main switch ON.
(c)
Select the item below in the DATA LIST, and read its value displayed on the hand–held tester.
