Toyota Tacoma (2015-2018) Service Manual: Acceleration Sensor Internal Circuit (C1419,C1435)

Toyota Tacoma (2015-2018) Service Manual / Brake Control / Dynamic Control Systems / Vehicle Stability Control System(for Hydraulic Brake Booster) / Acceleration Sensor Internal Circuit (C1419,C1435)

DESCRIPTION

The skid control ECU (master cylinder solenoid) receives signals from the yaw rate and acceleration (airbag sensor assembly) via the CAN communication system.

The airbag sensor assembly has a built-in yaw rate and acceleration sensor and detects the vehicle's condition using 2 circuits (GL1, GL2).

If there is trouble in the bus lines between the yaw rate and acceleration sensor (airbag sensor assembly) and the CAN communication system, DTCs U0123 (yaw rate sensor communication trouble) and U0124 (acceleration sensor communication trouble) are stored.

These DTCs are also output when calibration has not been completed.

DTC Code	DTC Detection Condition	Trouble Area
C1419	A data malfunction signal is received from the acceleration sensor.	Yaw rate and acceleration sensor (airbag sensor assembly)
C1435	A data malfunction signal is received from the yaw rate and acceleration sensor.	Yaw rate and acceleration sensor (airbag sensor assembly)

WIRING DIAGRAM

Refer to DTCs C1232, C1243 and C1245 (See page CAUTION / NOTICE / HINT ).

CAUTION / NOTICE / HINT

NOTICE:

When replacing the yaw rate and acceleration sensor (airbag sensor assembly), perform calibration (See page PROCEDURE ).

PROCEDURE

1.	CHECK CAN COMMUNICATION SYSTEM

(a) Check for DTCs (See page Result ).
