DESCRIPTION
After all transmitter 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.

C2126/26 |
Transmitter ID not Received in Main Mode |
After transmitter ID registration is completed, ECU does not receive radio waves from transmitters whose IDs are stored in ECU. |

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

PROCEDURE
1. |
IDENTIFY TRANSMITTER NOT RECEIVED |
(a) Set the tire pressure to the specified value (See page
).
(b) Turn the ignition switch off.
(c) Connect the Techstream to the DLC3.
(d) Turn the ignition switch to ON.
(e) Turn the Techstream on.
(f) Enter the following menus: Chassis / Tire Pressure Monitor / Data List.
(g) Display the "ID Tire Inflation Pressure" value for each wheel using the Techstream.
(h) Rapidly reduce the tire pressure for each wheel at least 40 kPa (0.4 kg/cm2, 5.8 psi) within 30 seconds. If the "ID Tire Inflation Pressure" value displayed on the Techstream does not change, the tire pressure warning valve and transmitter corresponding to the unchanged "ID Tire Inflation Pressure" value was the cause of the output DTC.

Rear Airbag Sensor LH Circuit Malfunction (B1635/24)
DESCRIPTION
The airbag sensor LH consists of parts such as the safing sensor, the diagnostic
circuit and the lateral deceleration sensor.
When the airbag sensor assembly receives signals from the lateral deceleration
sensor, it determines whether or not the SRS should be activated.
