SCCM-A018
SCCM_a018_angleSpeedOutOfRange
What does SCCM-A018 mean?
Tesla alert code in the Steering Column Control Module (SCCM) module. Steering Angle Sensor Speed Threshold Exceeded Supercharger timed-out during the voltage matching part of the sequence Voltage matching took too long to occur and the Supercharger timed out Voltage matching is successful and vehicle closes FC contactors Vehicle will not close FC contactors and charging will not start up. Supercharger measuered a low isolation measurement while connected to the vehicle. Supercharger isolation measurement result was less than the fault threshold Supercharger isolation measurement result is greater than the fault threshold Breakdown of isolation on the Supercharger or Vehicle's HV link. Supercharger did not receive all of the expected messages from the BMS. All BMS messages where received by the Supercharger. An emergency shutdown can occur while charging, or charging may never start up. Could not determine the status of the Proximity connection between the vehicle and the Supercharger Proximity Voltage is not within any valid range while connected to a Supercharger. Proximity returns to a valid value. Supercharger detected a voltage arc, either legitimately, or as a result of the HV circuit being opened under load. Supercharger detects a rapid change in energy on the HV bus, matching the signiture for an arc Supercharger has shutdown or been disconnected. May result in thermal damage to components, or welding/fatigue on FC contactors.
