Title: BRAKE CONTROL: VEHICLE STABILITY CONTROL SYSTEM (for Vacuum Brake Booster):
C1232,C1243,C1245; Acceleration Sensor Stuck Malfunction; 2016 MY Tacoma [08/2015 - ]
DTC C1232 Acceleration Sensor Stuck Malfunction
DTC C1243 Acceleration Sensor Stuck Malfunction
DTC C1245 Acceleration Sensor Output 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 acceleration sensor and detects the vehicle condition.
If there is trouble in the bus lines between the yaw rate and acceleration sensor (airbag sensor assembly) and the
CAN communication system, the DTC U0124 (malfunction in CAN communication with the acceleration sensor) is
output.
These DTCs are also output when calibration has not been completed.
DTC
NO.
