Title: TIRE AND WHEEL: TIRE PRESSURE WARNING SYSTEM: C2126/26; Transmitter ID not Received in Main
Mode; 2015 MY Tundra [08/2014 - ]
DTC
C2126/26 Transmitter ID not Received in Main Mode
DESCRIPTION
After all IDs are registered, DTC C2126/26 is set in the tire pressure warning ECU and the tire pressure warning
light blinks for 1 minute and then comes on.
When the tire pressure waning ECU successfully receives radio waves from all the transmitters whose IDs are
stored in the ECU, DTC C2126/26 is deleted and the tire pressure warning light goes off.
DTC NO.
DTC DETECTION CONDITION
TROUBLE AREA

INSPECTION PROCEDURE
NOTICE:
When replacing the tire pressure warning ECU, read the IDs stored in the old ECU using the Techstream
and write them down before removal.
It is necessary to perform initialization
after registration
PROCEDURE
1.
IDENTIFY TRANSMITTER NOT RECEIVED
(a) Set the tire pressure to the appropriate specified value(s)
.
(b) Turn the ignition switch off.
(c) Connect the Techstream to the DLC3.

A
It takes about 5 to 6 minutes to display the updated tire pressure data.
When no "ID Tire Inflation Pressure" data has changed, reset the tire pressure to the appropriate specified
value and rotate the tire 90 to 270°. Then rapidly release the tire pressure and recheck it.
Record the "ID Tire Inflation Pressure" data transmitter ID that corresponds to each tire.
(i) After confirming that the "ID Tire Inflation Pressure" data for one tire (ID1 to ID4) has changed,
repeat this procedure one by one. Identify the transmitter not received.
