ERR 01 is a lens to body communication error. Clean the lens and body contacts (put a small amount of alcohol on a Q-tip - do not use rubbing alcohol!!!). Try again. If that doesn't work, problem may be in lens or body. Using the flat of your fingernail, push in the contacts on the body inside the mirror box to clean any tarnishing between the contacts the the circuit (they are spring loaded). Try another lens - if the other lens works, then your problem is in the first lens. If it still gives the ERR 01 code then the problem is in the body.

Has the camera been impacted or had water/liquid spillage?

01 Pend:00 n/a 01/01 Code means that there is one code set, but no pending codes, and it also means that one code is set and one code is in history. You will have the option to go to the next screen on the scanner to see what the set code is, it would be a four-digit code and may also have a letter at the beginning.

Err 01

Description: The communication between the camera and lens is faulty.
Resolution: Very gently clean the electrical contacts (highlighted in red) on the camera and the lens using a clean and dry cloth.

you have a faulty SYSCON MICROCONTROLLER.+faulty associates circuits, like CLKS, RESET.
you must go to the repair shop TV for fix it.
However you can try as the last thing before to go the repair shopt, Clean tHE VHS+DVD, with tape cleaner+disc cleaner too.and Proof
God bless you.

You didn't say which shooting mode you're using, but I'd bet you're in Manual mode and have dialed in a completely wrong aperture/shutter speed combination for bright lighting conditions. For example, 1/60th of a second and f2.8 in bright sunlight would be "burning out" your image, so the camera may be giving you an error message. Try using AUTO or PROG setting and see if the problem persists. If it does, try a different lens. You may have an incompatible mount, or one of the contacts may be damaged. If all else fails, try your lens on another Canon camera.

Clean the camera / lens contacts with a lint-free cloth

err 3 is not an engine system fault code, a tyupical code looks like this P0420, this happens to be a evaporative emission system fault code.

this generally means the laser is either dirty or the cd player is shot, err 01 is a disc reading problem. Try cleaning lens with cleaning disc first if this does not help i would replace the unit with another. i would recommend replacing it with a cheap aftermarket stereo.
