Showing 1–22 of 22

• SCCM_a001 — Voltage High SCCM_a001_voltageHigh Alert for detecting if measured local input power supply is above max voltage range of 18V for 15 seconds.
• SCCM_a002 — Voltage Low SCCM_a002_voltageLow Alert for detecting if measured local input power supply is below min voltage range of 8V for 15 seconds
• SCCM_a003 — Angle Out Of Range SCCM_a003_angleOutOfRange Alert for detecting if the measured steering angle is out of +/- 492 degrees range.
• SCCM_a004 — Angle Speed Out Of Range SCCM_a004_angleSpeedOutOfRange Alert for detecting if the measured steering angle sensor speed is out of +/- 3000 degrees/second range.
• SCCM_a005 — Angle Not Plausible SCCM_a005_angleNotPlausible The steering angle sensor detected an implausible angle error. Steering may not operate as expected.
• SCCM_a006 — Angle Speed Not Plausible SCCM_a006_angleSpeedNotPlausible Alert for detecting an instantaneous angle speed plausibility error.
