DTC C123C: Abnormality in G and yaw rate sensor (lateral G and yaw rate sensor)
M13506100060USA0000010000
If there is any problem in the CAN bus lines, an incorrect
diagnostic trouble code may be set. Prior to this diagnosis,
diagnose the CAN bus lines. (Refer to GROUP 54D, Trouble
code diagnosis P.54D-17).
ACTIVE SKID CONTROL SYSTEM (ASC)
35C-135
DIAGNOSIS
CIRCUIT OPERATION
⦆
ASC-ECU supplies power to the G and yaw rate sensor at the
terminal No. 1.
⦆
The G and yaw rate sensor outputs the signal to ASC-ECU via
the CAN bus lines.
DTC SET CONDITIONS
This diagnostic trouble code is set if any malfunction below is
found:
⦆
The output value of lateral G and yaw rate sensor is abnormal.
⦆
When abnormality is detected by comparing the value output
from the lateral G and yaw rate sensor with the one from the
steering wheel sensor and wheel speed sensor
PROBABLE CAUSES
⦆
Improper installation of the G and yaw rate sensor
⦆
G and yaw rate sensor malfunction
⦆
Steering wheel sensor malfunction
⦆
Malfunction of wheel speed sensor
