SOURCE: the rev counter indicates 500 revs on tick over

If you have the correct 4 digit code, you should be able to input it right in. After 3 unsuccessful attempts i will lock out. Push the BND button and hold until radio says code in.

2 ways to get the correct code
1. Giving your VIN# to the land rover dealer in exchange for the radio.
2. If that code doesn't work, you will need to have the radio pulled and provide them with the serial # to the radio and provide that to the dealer.

SOURCE: central locking not working on drivers and passenger door

I am having a similar problem with left rear door. I replaced the lock actuator, but it was still not working properly. The trick is getting the door handle in the right spot. The door handle is attached by a cable, and over time the cable is stretched. I used a rubber stopper behind the handle to get it into the exact right position and it worked perfectly.

SOURCE: Where are the camera lens located on the lift gate?

check under the lift gate handle or in the handle, a quick trick would be to have some one inside truck put in reverse apply e brake and also hold the brake and wave your hand around the rear handle and let them tell you when you are in front of it.

Might be that the aperture is stuck and you need to get the lens repaired (might cost more than a new lens.) Or it might just be bad contacts. Clean the contacts and try another lens before asking Canon or dismantling the lens.

I have an error 01, communication between the camera and lens is faulty, it says to clean the lens contacts. I have a 60d canon body it does it only with the 17-85 lens how do I clean the contacts...

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 s
till the same error - ship it off to Canon for service.

Hope helps.

Hello, I mounted 12-24 mm f4 Tokina lens on my canon 7D, but when I change the aperture from F4 to anything else, I get this error message"camera cannot communicate with the lens, clean lens...

Did you clean the lens contacts with a pencil eraser or with something else? If memory serves F4 is wide open on this lens, right?

Bought june 2009 in june. rebel eso also with that package a cannon lens 75 to 300 used it 3 times on the camera code say err 01 clean contacts did that same old problem i also have a 3 year plan...

I'm not 100% sure of what you are saying. I gather you have a 3-year extended warranty? Error 01 is usually associated with failure of the IS system in the lens so it would most likely need to be sent to Canon for repair. I have only had one Canon service issue (nine years since my first EOS) and they provided an RMA for UPS return to them. I suggest you contact CanonUSA repair and request an RMA.

My cannon rebel eos DS6041 displays error 99 when

'Error 99' indicates some problem with the AF contacts. This is a common error in Canon lenses. It could indicate a very simple problem like dirty contacts or a much serious one like the breakage of USM cable.
As a first step, you can try cleaning the lens and body contacts (the metal contacts between the lens and body) using a pencil eraser. Be careful to hold the body facing down so that no dust falls inside. After cleaning both the lens and the body contacts, re-attach the lens and try shooting. If the AF does not work still, you need to take the lens to an authorized service center.

Error code

Yes, Canon DSLRs are very sensitive to some NON-Canon lenses.
If firmware inside the camera detects foreign lens, it locks-up the camera.
Basically, Canon wants you to buy only Canon lenses.

Cannon ef-s 18-55 f/3.5-5.6 lens

"err99" means the camera cannot talk to the lens which is why the camera is not working in auto mode with that lens. There could be several issues: 1. clean the contacts between the camera and body (the gold pins and conact plates on the lens); 2. dismount and remount the lens and perhaps it is just not correctly making contact; 3. remove the battery and let set and then replace and try again (usually doesn't work); 4. make sure that the only thing between the lens and the body is nothing; 5. otherwise either the lens or the body is defective.

Good luck
