Possible causes for the Check Control message lighting up can be:

• Fault in the EPS control unit, in an integrated sensor or in the servomotor
• EPS overheat protection
• Undervoltage or overvoltage
• Failure of external signals with influence on steering power assistance
• Faulty or incomplete initialization of the steering (e.g. learning end stops)
