Unspankable:
It depends on who installed it. If it was a young mechanic following the instructions, you will need to lift the pltform to get the nuts off the bottom of the wall. If the mechanic who installed it also troubleshoots them, odds are he skipped the nuts and you can just take the ones off the top of the side panel. That being said, if you are down that low, the controller is above the first joint of the cover panels (assuming its a v1504). No need ti remove platform panels.
