DTC CHECK / CLEAR
1. DTC CHECK (USING SST CHECK WIRE)
(a) Check DTCs.
(1) Using the SST, connect terminals TC and CG of
DLC3.
SST 09843±18040
(2) Turn the ignition switch to the ON position.
(3) Read and record any DTCs from the tire pressure
warning lamp on the combination meter. Refer to
the illustration on the left for examples of a normal
system code and codes 13 and 33.
HINT:

If the tire pressure warning lamp does not blink any DTCs
or the normal system code, inspect the tire pressure
warning lamp circuit or TC terminal circuit.

If 2 or more malfunctions are indicated at the same time,
the lowest numbered DTC is displayed first.
(4) Refer to the Diagnostic Trouble Code Chart (see
page DI±825) for DTC information.
(5) After completing the check, turn the ignition switch
off and remove the SST from DLC3.

HINT:

If no abnormality is found when the parts are inspected, inspect the tire pressure monitor ECU.

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

CIRCUIT DESCRIPTION
The tire pressure monitor valve sub±assy stops transmitting signals when receiving specific signals. The
ECU stores the DTCs when the tire pressure monitor valve sub±assy receives the signals, for some reason,
and stops transmitting signals. As this is not a system malfunction, the DTCs are erased when signal trans-
mission is resumed.
HINT:
The electric wave is stopped at assembly plant, because the strength of the electric wave emitting from the
tire pressure sensing transmitter does not comply with the Japan Wireless Telegraphy Act.

HINT:
It is necessary to perform the procedure to identify the tire pressure monitor valve sub±assy that is malfunc-
tioning 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±assy and/or
the tire pressure monitor ECU (see page DI±805).
HINT:
Set the tire pressure to the specified value.
1 Forcibly transmit transmitter ID of all wheels.
PREPARATION:
Remove the valve cores of the all wheels to rapidly reduce the pressure of all tires to 120 kPa (1.2 kgf/cm2,
17 psi respectively).
HINT:
The transmitter ID can be transmitted forcibly by rapidly reducing tire air pressure.
NEXT
2 Check DTC (See page DI±820).
CHECK:
Check for a DTC.
OK:
DTC is not output.
OK Set tire pressure to normal value (Transmitter
stop condition is completely reset).
NG
3 Set tire pressure to normal value.
PREPARATION:
Set the tire pressure back to the specified normal value.
