Steering System364Service Manual – CS70004. The Steering faults menu displays all of the codes that have ever been set in the system. The codes aredisplayed in “reading order”, separated by commas and are sorted with the most recent at the top left.See the Diagnostic Trouble Code Table below to look up what the code means.5. To exit, press the solution button.Diagnostic Trouble Code TableDTC Error Source Description Check0 AC Current –ExcessiveThe hardware detected excessivecurrent flow in the steering actuatormotor circuits.Actuator - shorted/burned statorwindings.Wiring (U, V & W) - Shorted to groundor one another.Steering Controller - Internal ShortNote: Can also be caused by too low DCsupply voltage on B+.1 DC PowerSupply - LowVoltageThe software detected that the DCpower supply (B+ and B-) voltage istoo low.Battery Positive and Negativeconnections at source and controllerBattery Positive and Negative cables2 DC PowerSupply - HighVoltageThe software detected that the DCpower supply (B+ and B-) voltage istoo high.Battery Positive and Negativeconnections at source and controllerBattery Positive and Negative cablesNote: If there is too much resistancebetween the controller and the batteryduring regenerative braking, thevoltage can climb.3 DC PowerSupply - HighVoltageThe hardware detected that the DCpower supply (B+ and B-) voltage istoo high.Battery Positive and Negativeconnections at source and controllerBattery Positive and Negative cablesNote: If there is too much resistancebetween the controller and the batteryduring regenerative braking, thevoltage can climb.4 DC PowerSupplyInsufficientThe B+ and B- cables did not supplyenough current to charge a capacitorinside the controller within 10seconds.Battery Positive and Negativeconnections at source and controllerBattery Positive and Negative cables
