Function Defective Components
Pressure sensor
Cause
- Abnormal signals from pressure sensor
- Defective pressure sensor or harness
Action
- Check the pressure sensor connector
Steering wheel angle
Cause
- Internally defective steering wheel angle sensor
- Abnormal signals from steering wheel angle sensor
- Short circuit between supplying voltage output and ground
- Abnormal signal voltage from steering wheel angle sensor
- Poor installation of steering wheel angle sensor and abnormal signal
Action
- Check the supplying voltage: (Specified voltage: 9 ~ 16 V)
- Check the output voltage: Check voltage between ESP unit terminals with ignition ON
Sensor
• ST1 voltage check: between ESP unit terminal No. 5 and ground (Specified voltage:
Monitoring
1.3 ~ 4.1V)
• ST2 voltage check: between ESP unit terminal No. 2 and ground (Specified voltage:
1.3 ~ 4.1V)
• STN voltage check: between ESP unit terminal No.12 and ground (Specified voltage:
1.3 ~ 4.1V)
Sensor cluster
1. C1073 (5073)
Cause
- Operating voltage exceeds specified range (Hi: 18.0 ± 1.0 V / Lo: 6.5 ± 0.5 V )
- Poor contact or installation of harness
Action
- Check the sensor cluster connector
- Replace the sensor cluster
2. C1074 (5074)
Cause
- Internally defective HECU
- Abnormal A/D converter voltage: 5.0 ± 3 %
- Abnormal supplying voltage (4.580 ~ 4.960 V) to sensor cluster
→ Short circuit between supplying voltage output of sensor cluster and ground
- Poor ground of sensor cluster (0.0 ~ 0.5 V)
→ Short to ground on sensor cluster
- Abnormal signals from lateral acceleration sensor
- Abnormal signals from yawing sensor
- Poor installation of sensor
- Defective sensor cluster
- Defective or short circuit of CAN communication line
Action
- Replace the sensor
