DESCRIPTION
The skid control ECU receives signals from the yaw rate and acceleration sensor via the CAN communication system.
The yaw rate sensor has a built-in acceleration sensor.
If there is trouble in the bus lines between the yaw rate and acceleration sensor and the CAN communication system, DTC U0123/62 (Lost Communication with Yaw Rate Sensor Module) is output.

CAUTION / NOTICE / HINT
HINT:
When U0123/62 and/or U0126/63 is output together with C0365/28, C1234/34, C1245/32
and/or C1245/45 inspect and repair the trouble areas indicated by U0123/62 and/or
U0126/63 first (See page ).
PROCEDURE
1. |
CHECK DTC |
(a) Clear the DTCs (See page ).
(b) Start the engine.
(c) At a speed of 30 km/h (18 mph) or more, drive the vehicle, turn the steering wheel, and decelerate (depress the brake pedal) the vehicle.
(d) Turn the ignition switch to ON again and check that no CAN communication
system DTC is output (See page ).

2. |
CHECK YAW RATE AND ACCELERATION SENSOR INSTALLATION |
(a) Turn the ignition switch off.
(b) Check that the yaw rate and acceleration sensor has been installed properly
(See page ).
OK:
The sensor should be tightened to the specified torque.
The sensor should not be tilted.
