Identify transmitter (Error in past)
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.

The following are the procedures to identify which wheel's transmitter ID1 is resulting from when as-
suming 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.
IDENTIFICATION PROCEDURE

DIAGNOSTIC TROUBLE CODE CHART
NOTICE:

When removing parts, turn the ignition switch OFF.

When replacing the master cylinder, yaw rate and deceleration sensors and/or the ECU, make
sure to perform master cylinder, yaw rate and deceleration sensors' zero point calibration (See
page DI±897).
HINT:

Using SST 09843±18040, connect terminals Tc and CG.

If no abnormality is found when inspecting parts, inspect the ECU.

If a trouble code is displayed during the DTC check, check the circuit listed for that code. For details
of each code, turn to the page referred to under the ºSee pageº for respective ºDTC No.º in the DTC
chart.

DTC C1337 / 37 Some Tire Are Different in Size From
the Other Tires
CIRCUIT DESCRIPTION
Skid control ECU measure the speed of each wheel by receiving signals from speed sensor. These signals
are used for recognizing all 4 wheels are operating properly. Therefore, all wheel signals must be equal.
DTC No.DTC Detecting ConditionTrouble Area
C1337 / 371 or 2 tires of different size are used for driving.Tire size
INSPECTION PROCEDURE
1 Check tire size.
CHECK:
Check tire size and condition of all 4 wheels.
NG Replace tires so that all 4 tires are the same in
size.
OK
2 Check speed sensor (See page DI±925).
NG Replace speed sensor.
OK
3 Check speed sensor rotor (See page DI±925).
