CAN-AM DEFENDER HD10 Power Steering Not Working

40 Amp J-Case Fuse

This fuse is the primary circuit protection for the DPS motor. High-torque maneuvers or electrical surges can cause this fuse to blow, resulting in a total loss of assist while the rest of the vehicle's electronics remain functional.

12V AGM Battery

The DPS module requires high amperage and stable voltage (above 12.5V) to operate. If the battery's internal resistance increases or it cannot sustain load, the DPS ECU will disable the assist motor to prioritize engine ignition and critical systems.

Dynamic Power Steering (DPS) Motor Assembly

Internal electronic failure of the torque sensor or motor current sensor within the sealed unit. When these sensors provide data outside of the expected parameters, the unit enters a fail-safe 'manual' mode, and since the sub-components are non-serviceable, the entire gear/motor assembly must be replaced.
