Home Forums General Discussion Technical Questions TAC 50 traction #90 Fault

Could anybody give me some info for this Fault ? Doors also failing to open. Thank you

Does this job have freight doors?

Yes. Peele. Sorry forgot to say that. Was before coffee- car has front and rear doors. Rear is working fine but front doors open automatically which they never did before - can close the door and she runs - take car to a floor , get out and press door close - they close up. Take finger off the close button then about 5 seconds later they will re-open

90 is Freight doors were commanded to open but did not open.

I would go through the zone switch contacts first and clean em up,then check dol and dcl,and door closed contact
Make sure lock is dropping out also.

I'll get to work on that. - thanks guys
