2005 SEQUOIA (RM1146U)
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.

4 Forcibly transmit transmitter ID.
PREPARATION:
(a) Forcibly transmit the transmitter ID by performing the following:
(1) Set the tire pressure to the specified value.
(2) Rotate the tire 90 to 270 degrees.
(3) Rapidly reduce the pressure of all tires to 120 kPa (1.2 kgf/cm
2, 17 psi respectively).
(4) Perform the steps mentioned above to all tires including the spare tire.

5 Check DTC (See page DI±820).
CHECK:
Check for a DTC.
OK:
DTC is not output.
HINT:
A system error is probable if NG. If any DTC other than C2111/21, C2112/22, C2113/23, C2114/24 and
C2115/25, is output, perform troubleshooting according to that DTC.
OK Set tire pressure to normal value (Transmitter
stop condition is completely reset).
NG
6 Check DTC (See page DI±820).
CHECK:
Check if DTCs C2111/21, C2112/22, C2113/23, C2114/24 and C2115/25 are all output.
No Go to step 12.
