U0001 Mercury Code - High Speed CAN Communication Bus
Quick Answer
The Power Steering Control Module (PSCM) monitors the HS-CAN bus when the ignition has been on for more than 5 seconds, when the voltage to the PSCM is greater than 9 volts and when there is no Diagnostic Trouble Code (DTC) present that is inhibiting PSCM operation. Common causes include Faulty Power Steering Control Module (PSCM), Power Steering Control Module (PSCM) harness is open or shorted, Power Steering Control Module (PSCM) circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.
