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) |
•
Calculated Yaw value under stabilized driving condition and measured Yaw sensor value difference is over 3.5 deg, it enters suspicious mode and this suspicious mode continues
•
After Engine "ON" and initial standstill condition, Absolute value of Yaw sensor is greater than 30 deg/sec for more than 5 sec.
•
Absolute value of Yaw sensor is greater than 95 deg/sec for more than 1 sec during driving | |
Case 2(Sensor Offset) |
•
Pre Yaw Offset and calculated average Yaw offset difference is greater than 3 deg/sec. under standstill condition
•
Pre Yaw Offset and calculated average Yaw offset difference is greater than 3 deg/sec. while driving with over 30 km/h(Approx. 18.6 mph) and straight stabilized condition | ||
Case 3(Abnormal Lateral G Signal) |
•
Calculated Lateral G value under stabilized driving condition and measured Lateral G sensor value difference is over 3 m/s2, it enters suspicious mode and this suspicious mode continues
•
Absolute value of Lateral G sensor value is greater than 15 m/s2
•
Difference of Lateral G sensor Value is greater than 11 m/s2 | ||
Case 4(Lateral G Offset) |
•
Pre Lateral G Sensor Offset and calculated average Lateral G Sensor offset difference is greater than 7 m/s2. under standstill condition
•
Pre Lateral G Sensor Offset and calculated average Lateral G Sensor offset difference is greater than 2.5 m/s2. while driving with over 30 km/h(Approx. 18.6 mph) and straight stabilized condition | ||
Case 5(Abnormal Longitudinal G Signal) |
•
Calculated Longitudinal G sensor signal and measured Longitudinal G sensor value difference is higher than 4.5 m/s2 for more than 2 sec.
•
Sensor value is higher than 15 m/s2 for more than 1 sec during no control condition
•
AXStat Signal is 1 or 2 or AX = 0xFFFF | ||
Warning Indicator Lamp Status |
•
ESC(ESP) Warning Indicator Lamp "ON" | ||
Clear Condition |
•
Ignition "OFF" and then "ON" and Vehicle speed over 12 km/h (Approx. 7 mph) | ||
