Question about Canon EF-S 17-55 f/2.8 IS USM Lens
How can I fix that?
Posted by Anonymous on
Remove the rear lens cap and you'll see a row of metal contacts. Simply use a clean pencil eraser rubbed over the contacts.

I having a similar problem and send back to the Canon service centre for repair. Subsequently, it was confirmed that the aperture diaphragm is faulty and need to be replaced.

SOURCE: I've been using the Canon
The pencil eraser trick works although Canon repair say don't use this method yet behind closed doors they do the vary same thing. Just make sure you have cleaned the gold contacts well of eraser dust with a lens cloth not a tissue. The reason you should use a new clean eraser is because it hasn't been used for its intended purpose and you haven't just successfully transferred pencil lead, ink and bleach to the contact surface. Use a new eraser only and if the problem still hinders you then I would suggest upgrading your camera firmware which is a free download from the Canon site. As the camera can't talk to you the only way of communicating a problem is through error codes however there isn't enough error codes to cover all possibilities. This meaning that the lens connection may be what the book said but in fact it could be a battery connection problem as well OR if you have a battery grip the contacts there can also give a little head ache. Clean them all and then do the firmware update and you will be back into the photography in no time cheers have a great day

Have you tried cleaning the contacts? Taking out BOTH batteries? (There's a button cell as well as the main battery.) If you have a second lens you can test, i'd give that a shot first.
Either way, probably need to have it replaced or repaired right away.
Finally, have you got the latest firmware version? The XS is currently at version 1.0.5, which was released in April of this year. You can download it here.
Also, could check this link: 50mm-lens-contact-points and the video, as reference...
If this choice dont solve and still the same error - ship it off to Canon for service.

The flat printed cables inside the lens unfortunately develop small cracks over the years and this causes the lens to fail. The repair is NOT easy, you have to tear down the lens all the way to it's base components and replace the flex cable on the aperture diaphragm. The cable and the diaphragm are available online, but again it's not a simple repair and most people should not attempt it themselves.
