General Troubleshooting Methodology - Precor TRM 885.v2 Service Manual

General Troubleshooting Methodology


When you first approach the treadmill, first note the condition of the ASL. This will help
to save you time by pointing out where your next step should be. By using the
combination of the status lights and the error code list, you should be able to quickly
determine your troubleshooting plan of action preventing you from following unnecessary
steps, working more efficiently.


Some faults with the treadmill will not have an error code logged, nor will the status
LED's change. Most of these will be mechanical in nature – noises, loose parts etc. An
exception to this is the belt/deck wear which is indicated by the ASL pulsing blue, but will
not generate an error code.

If the treadmill does not turn on, trips the breaker or the console will not illuminate:
o Follow the appropriate procedure for Troubleshooting Tripped Breakers or
Troubleshooting No Power to the Console.

If the system powers up and can be at least partially operated:
o Look for the ASL and MCL note their status.
o Look in the error log for system information (drive system, lift system, etc) as
appropriate
o Clear the error log (which will also reset the ASL), and attempt to duplicate the error.
o Run the unit in the Hardware Validation Tests and verify that the console and base
are working normally.
o Note any other observations you may notice about the treadmill – noises, stability,
etc.
o Isolate the fault to the system or component, repair or replace as required.
o Retest the full functionality of the treadmill.
IMPORTANT If a failure is observed in user mode but works perfectly in the hardware validation tests:

note

Additionally, it is a good idea to be familiar with the recent service bulletins for the treadmill, the
problem you are facing may already be known and addressed, saving you time troubleshooting.

appearance of a failure, such as the incline limit set to 0, or the Units set to
Metric or US Standard.
