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 and acceleration 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, DTCs U0124 (Lost Communication with Lateral Acceleration Sensor Module) are set.
These DTCs are also output when calibration has not been completed.

CAUTION / NOTICE / HINT
NOTICE:
When replacing the yaw rate and acceleration sensor (airbag sensor assembly),
perform zero point calibration and store system information (See page
).
HINT:
When U0124 and/or U0126 is output together with C1419 and/or C1435, inspect and
repair the trouble areas indicated by U0124 and/or U0126 first (See page
).

PROCEDURE
1. INSPECT 3RD GEAR THRUST CLEARANCE
(a) Using a dial indicator, measure the 3rd gear thrust clearance.
Standard clearance:
0.200 to 0.490 mm (0.0079 to 0.0192 in.)
If the clearance is outside the specification, replace the 3rd gear,
thrust washer, c ...
