Precor Error Code 55 Holding Brake Manual Release Detected

Mar 19, 2022

Applies to SCL800

Issue Symptoms

Error 55 occurs when a workout is started and the Holding Brake Lever is in the OFF "Released" position. The Holding Brake Lever must be in the ON "Normal" position to start a workout.

The LPCA detects that the Holding Brake Manual Release lever switch signal is continuously in the Manual Release active state for longer than 5 seconds.

The most likely cause of error 55 is that someone such as a servicer has manually released the holding brake lever.

Troubleshooting steps

1. Check the position of the Holding Brake lever. If the lever is in the OFF position (fully back), move the lever to the ON position (fully forward).
2. If the lever is in the ON position (fully forward) with an error 55:
   1. Make sure the Holding Brake cable is connected to the LPCA connector (J3).
3. Substitute the Brake assembly with a known good condition Brake assembly.
   1. If Error 55 is resolved, replace the original defective Brake ass.
4. Replace the LPCA.
