Title: BRAKE CONTROL: VEHICLE STABILITY CONTROL SYSTEM (for Vacuum Brake Booster): C1436; Yaw Rate
Sensor Malfunction; 2016 MY Tacoma [08/2015 - ]
DTC C1436 Yaw Rate Sensor Malfunction
DESCRIPTION
The skid control ECU (brake actuator assembly) receives signals from the yaw rate and acceleration sensor
(airbag sensor assembly) via the CAN communication system.
The airbag sensor assembly has a built-in yaw rate sensor and detects the vehicle condition.
If there is trouble in the bus lines between the acceleration sensor (airbag sensor assembly) and the CAN
communication system, DTC U0124 (Lost Communication with Lateral Acceleration Sensor Module) is set.
These DTCs are also output when calibration has not been completed.
DTC
NO.
DETECTION
ITEM
DTC DETECTION CONDITION TROUBLE AREA

With the vehicle stationary, the yaw
rate and acceleration sensor output
value is not 0 deg/s.
Abnormal comparison value.
Improper yaw rate sensor
(Airbag sensor assembly)
installation
Yaw rate sensor (Airbag
sensor assembly)
HINT:
DTC will be output when conditions for either of the patterns in the table above are met.
INSPECTION PROCEDURE
NOTICE:
When replacing the yaw rate and acceleration sensor (airbag sensor assembly), perform zero point
calibration and store system information .
HINT:
When U0124 and/or U0126 is output together with C1436, inspect and repair the trouble areas indicated
by U0124 and/or U0126 first .
PROCEDURE
1. READ VALUE USING TECHSTREAM (YAW RATE SENSOR)
(a) Connect the Techstream to the DLC3.
(b) Turn the ignition switch to ON.
(c) Turn the Techstream on.
