Probable Cause
Most commonly indicates a problem with the lower PCA when the error consistently appears. It is rare for a failure to occur that would cause this error.
Corrective Action
The lower PCA should be replaced if the error consistently appears at power-up.
External causes may make the error appear intermittently
- If the AC input of the unit dips significantly during power-up test sequences, the test could fail and cause the error to appear.
- A treadmill connected to a non-dedicated AC circuit can experience this error intermittently.
