DTC C2126/26 Transmitter ID not Received in Main Mode

DESCRIPTION

After all IDs are registered, DTC C2126/26 is stored in the tire pressure warning ECU and receiver and the tire pressure warning light blinks for 1 minute and then illuminates.

When the tire pressure warning ECU and receiver successfully receives radio waves from all the transmitters whose IDs are stored in the ECU, DTC C2126/26 is cleared and the tire pressure warning light goes off.

DTC No.	DTC Detection Condition	Trouble Area
C2126/26	After ID registration is completed, ECU does not receive radio waves from transmitters whose IDs are stored in ECU.	ID registration failure Tire pressure warning valve and transmitter Tire pressure warning antenna (for Rear Side) Tire pressure warning antenna (for Front Side) Harness or connector Tire pressure warning ECU and receiver

NOTICE:

For the ID switching function, (Main) is displayed on the DTC screen for the DTCs even when the 2nd set of tires is selected.

HINT:

The purpose of this DTC is to help prevent delivering a vehicle that has incorrectly registered IDs. After all IDs are registered, DTC C2126/26 is detected and the tire pressure warning light blinks for 1 minute and then illuminates. If the tire pressure warning light does not turn off after a little while, IDs may be incorrectly registered.

INSPECTION PROCEDURE

NOTICE:

When replacing the tire pressure warning ECU and receiver, read the transmitter IDs stored in the old ECU using the GTS and write them down before removal.

It is necessary to perform initialization () after registration () of the transmitter IDs into the tire pressure warning ECU and receiver if the ECU and/or one of the valve and transmitters has been replaced.

1.CHECK TEST MODE DTC (C2195/95)

Turn the engine switch off.

Connect the GTS to the DLC3.

Turn the engine switch on (IG).

Turn the GTS on.

Enter the following menus: Chassis / Tire Pressure Monitor / Utility / Signal Check.

Perform the test mode inspection ().

Result:
Result Proceed to
DTC C2195/95 is cleared A
DTC C2195/95 is not cleared B

GO TO DTC C2195/95 ()

2.IDENTIFY TRANSMITTER NOT RECEIVED

Set the tire pressure to the specified value ().

Turn the engine switch off.

Connect the GTS to the DLC3.

Turn the engine switch on (IG).

Turn the GTS on.

Enter the following menus: Chassis / Tire Pressure Monitor / Data List.

Check the values by referring to the table below.

HINT:

*: It may take a few minutes until the values are displayed.

The wheel position cannot be determined from ID1 through ID5 on the Data List.

Rapidly reduce the tire pressure for each wheel at least 40 kPa (0.4 kgf/cm², 5.8 psi) within 30 seconds.

Check the Data List.

NOTICE:

It may take a few minutes to display the updated tire pressure data.

When the "ID Tire Inflation Pressure" data has not changed, reset the tire pressure to the appropriate specified value and rotate the tire 90 to 270 degrees. Then rapidly release the tire pressure and recheck the data.

Record the "ID Tire Inflation Pressure" data transmitter ID that corresponds to each tire.

After confirming that the "ID Tire Inflation Pressure" data for one tire has changed, repeat this procedure one by one. Identify the transmitter not received.

Result:

3.CHECK TRANSMITTER ID

Turn the engine switch off.

Connect the GTS to the DLC3.

Turn the engine switch on (IG).

Turn the GTS on.

Enter the following menus: Chassis / Tire Pressure Monitor / Data List.

Check the values by referring to the table below.
