Hi guys, got two of these trucks on same site with same fault.

Both will show error A5 but only if you key up the truck after the battery has been plugged in for a long period, maybe 30 minutes or so.

If you've just plugged in the battery and keyed up error code never shows, if you leave ignition on all day error code never shows, hop on/off truck all day and it's fine but switch it off and go to lunch it'll always code up A5 when you re-key, to clear code customer unplugs battery for maybe 5-10 seconds and starts over again.

I'm wondering if it's a capacitor issue in the hydraulic controller or a key switch back feed issue, I've no wiring diagram or fault code manual but I'm drawn to these two areas first.

Thanks.
