KDC.716S Mech error issue

Replace worn breaker with new breaker - happens often due to high current when cleaning cycle is used!

Both. Check the power line that is supposed to power the clock and memory circuits when you turn off the ignition.

And your player has lost the ability of the laser to focus on the disc - hence the error message.

check battery cables one is loose

corrosion on you battery terminal will create high resistance.inspect the battery connectors and wire. if you find white/blue crystals on you terminal disconnect and clean. the battery cable must be gold/light brown.If the wire are black/blue that mean is burn from bad(lose) connection to the terminal and need replacement.Inspect all ground connection betvin battery and body for corrosion or lose

You should rewire it, if i remember correctly yellow wire should be connected to constant + (or directly to battery +) so the radio doesn't lose any settings when you turn it off

Battery connections good , battery ground cable connection on the frame an engine clean an tight ? No corrosion . I wouldn't look for any ground issues under your seat . No power , main cable problem , to starter etc...

You may have a bad flexible cable that goes from the face to the main board.

FLEX CABLE has been worn out, its thirty bucks and easy to install.

firstly you should remove the power from the unit for a few seconds to reset it. if this doesn't fix it you can remove the top lid and you will see the motor that rotates the fascia, if you unplug the flexible cable that powers the motor and put 6volts on the motor contacts till the fascia rotates and then plug the flexible cable back put the fascia back on and plug the power lead back on to the radio

yup.. needs a new face plate ribbon cable.. just like mine :-(
