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. |
Detection Item |
DTC Detection Condition |
Trouble Area |
---|---|---|---|
C1232 |
Acceleration Sensor Stuck Malfunction |
At a vehicle speed of 10 km/h (6 mph) or more, the acceleration sensor output value does not change for 30 seconds or more. |
|
C1243 |
Acceleration Sensor Stuck Malfunction |
Any of the following is detected:
|
|
C1245 |
Acceleration Sensor Output Malfunction |
At a vehicle speed of 30 km/h (19 mph) or more, the difference between the forward and backward G calculated from the acceleration sensor value and that calculated from the vehicle speed exceeds 0.35 G for 60 seconds or more. |
|
HINT:
DTC will be output when conditions for any of the patterns in the table above are met.
CAUTION / NOTICE / HINT
NOTICE:
HINT:
When U0124 and/or U0126 is output together with C1232, C1243 and/or C1245, inspect
and repair the trouble areas indicated by U0124 and/or U0126 first (See page
).
PROCEDURE
1. |
CHECK DTC |
(a) Clear the DTC (See page
).
(b) Turn the ignition switch off.
(c) Start the engine.
(d) At a speed of 30 km/h (19 mph) or more, drive the vehicle, turn the steering wheel, and decelerate (depress the brake pedal) the vehicle.
(e) Check that no CAN communication system DTC is output (See page
).
(f) Check if DTCs for zero point calibration of the yaw rate sensor undone (C1210)
or for zero point calibration of the acceleration sensor undone (C1336) are output
(See page
).

2. |
CHECK AIRBAG SENSOR ASSEMBLY INSTALLATION |
(a) Turn the ignition switch off.
(b) Check that the airbag sensor assembly has been installed properly (See page
).
OK:
The sensor should be tightened to the specified torque.
The sensor should not be tilted position.

AUTO LSD Indicator Light Remains ON
DESCRIPTION
During normal mode, pressing the VSC OFF switch for a short amount of time changes
vehicle to AUTO LSD mode.
