If you have a model with a detachable face there is a reset button under the face. Reset back to original state. If that doesn't work some of the older Kenwoods defaulted to the protect screen whenever there was a 'fault' in the system. ie. a shorted wire or blown speaker.

On my stereo kenwood kdc-w4537u will read protect what is the code to remove it?


The indication of Protect means that the amplifier of the stereo has encountered a serious fault and so is shutting down to prevent further damage. So this can be a damage on the hardware and so must be checked physically and replaced,. Normally the outputs or the power section can short and so result in the indication.

My kenwood car stereo model no. KDVMP5343U is showing protect while switching on


PROTECT (Blink): The speaker wire has a short-circuit or touches the chassis of the vehicle, and then the protection function is activated. Wire or insulate the speaker cable properly and press the reset button. If the "PROTECT" code does not disappear, consult your nearest service center.
Good luck with it

My stereo says" protect" everytime i turn it on. can't get anything else.


Hello grammagrisbo, hi your Kenwood head units will show "protect" when there's a problem with the speaker outputs so check to see if the impedance load meets your radio, 8ohms or 4 ohms?. having parallel two speakers on a single channel may cause this dilemma. This might also mean a shorted speaker wire, a blown speaker, or an internal defect in the head unit. Once the condition that's causing the "protect" mode is fixed, the CD player should be back to normal, the next time you turn it on.
If it's staying in "protect", then you'll definitely have to remove the stereo and do something to fix it. Many car audio stores will do system troubleshooting, for a fee. If you want to do it yourself, here's what you need to do:

Pull the Kenwood unit from the dash and disconnect all the speaker wires. power it on and see if the "protect" message displays. If it does, the stereo has an internal defect and will need to be serviced. If it doesn't, then turn it off, and re-connect one speaker only. Turn it on again and see if it will displays "protect" message.

If the radio works with one speaker connected, connect the other speaker to the second channel, you may have now the idea where the problem begun, you will identify the speaker that's causing the problem. There may be a wiring problem or defective speaker in that channel.

If it displays "protect" with a single speaker connected, then disconnect that one and try the other one. If all the speakers cause a "protect" mode, then you're probably back to a defective head unit.

Kenwood kdc-w3041 protect mode


Hello ia737,

The "protect" display is probably being caused by a shorted or grounded (touching vehicle chassis or other ground) speaker wire. Check the speaker wires for bare spots, etc and insulate or replace as necessary.

You do not need to remove the fuses to force a "cold reset" of the W-3041. You can simply press the "reset" button on the front of the unit. It's the little recessed button at the lower left of the volume control. Use the straightened end of a paper clip or ballpoint pen to momentarily hold the button in.

Hope this helps.

Security Code for Protect mode


Turn on the car so the radio is flashing "Protect." Look on the front / removable face of the stereo. On it you will find a small round hole - that's a reset button. Find a small paper clip, unfold the clip and stick it gently into the hole. The "Protect" will stop flashing, and Kenwood will be displayed. Unfortunately all your settings/presets will be gone, but at least the stereo is working again!
