If calculated G sensor value and measured G sensor value difference is out of specified value or sensor specification, HECU sets DTC C1283.
Item | Detecting Condition | Possible cause | |
DTC Strategy |
•
CAN Message Monitoring | 1. Faulty Yaw Rate & G Sensor Installation 2. Defected Yaw Rate & G Sensor | |
Threshold Value | Case 1(Abnormal Signal) |
•
G sensor value is over 0.7G for more than 1 sec. during vehicle is in standstill1)
•
G sensor absolute value is over 0.5G for more than 20 sec. during vehicle speed of over 10 km/h (Approx. 6 mph) upon brake lamp switch status is "OFF"2)
•
G sensor signal stuck calculated by comparing change rate of vehicle speed and G sensor value3) | |
Case 2(CBIT, Self Test) |
•
CBIT Test signal is out of sensor spec. upon CBIT test* Sensor Spec : Ax > 1.5g | ||
Case 3(Sensor Rolling Count Error) |
•
Rolling Count from the sensor does not increase for certain amount of time | ||
Case 4(Sensor Fail) |
•
Fail flag signal from sensor is received for certain amount of time | ||
Fail Safe |
•
CBC/TCS/ESC(ESP)/HAC/VSM/AVH inhibited (ESC[ESP] Only) | ||
Warning Indicator Lamp Status |
•
ESC(ESP) Warning Indicator Lamp "ON" | ||
Clear Condition |
•
Ignition "OFF" and then "ON"
•
2), 3) condition of Case 1 : Change in G sensor signal or minimum of 10 km/h(Approx. 6 mph) vehicle speed | ||
