Diagnostic Aids
- DTC C0176 54 does not indicate that a malfunction has occurred. Rather that the power steering control module had to limit current to the power steering motor to avoid thermal damage to the power steering system components. Discuss with the customer about driving conditions when the steering assist was reduced.
- Ensure that no steering components down stream of the power steering column assembly, such as ball joints, tie rod ends, universal joints, or the steering gear assembly, are mechanically binding.
- Most instances of DTC C0176 setting are due to excessive steering inputs. Examples of excessive inputs:
- Steering wheel turned to the end of the rack travel and held there for an extended period of time (30 seconds)
- Steering turned from endstop to endstop repeatedly (10 times)
