8. What does the code '4401' mean?

The fault code '4401' may be seen from time to time in the fault logs of VSI, VR2, Egis & S-drive. If our controllers detect a fault with the electrical system of a mobility vehicle, they will bring the powerchair or scooter to a stop & output a 4-digit diagnostic code. This code can be read with one of our hand-held or PC programmers. In addition to this 'live' information; the code is stored in a historical system 'log' which assists dealers in investigating intermittent faults.

If the 'live' code is classed as a possible controller fault, it will be recorded in the system log of a VSI, VR2, Egis or S-drive as a '4401'. (On older products the code will simply be stored as it appeared at the time). Our system logs can hold up to 8 different fault codes & record up to a maximum of 31, (Egis) 99, (VSI) or 255, (S-drive) instances of each of these individual codes. Recording suspected controller faults in this way, by utilising one unique code, '4401', means the other 7 log locations are kept free for system faults such as low batteries, open circuit motor connections etc. which you the customer can address yourself.

If when investigating the historical log of a VSI, VR2, Egis or S-drive, you come across '4401' faults, start by checking the connections, motors & batteries. If further '4401' codes are recorded after this initial check, you can return the controller to our Customer Services department who will repair & return it to your company, free of charge, provided the controller has not been damaged by the end-user. As a general rule, a '4401' error will point to a possible controller fault but occasionally a '4401' error may be recorded as a result of a system problem. The controller will always try to assume the safest condition, which is to 'trip' if there is any doubt. One such example has been observed on small scooters with removable batteries, if the batteries are replaced with the keyswitch still in the 'on' position a '4401' fault may occasionally be recorded.

If you have access to O.E.M. or 'B' level programming software, it is possible to break down the '4401' entries into their original constituent codes. As always, if you are unsure about whether or not to return a controller, please contact us for further advice, we're here to help! Alternatively, if you would like additional training on how our controllers can assist with fault diagnosis, please e-mail The Training Department to arrange a convenient date.
