20 Most Recent Pioneer DEH-225 CD Changer Questions & Answers

You need three wires to power on a radio
yellow 12v constant
red 12v switch (turns off/on with key)
black ground

Verify these three and the fuse on the back of the radio as well

I went to the local sterero shop and they answered my question about the harness.

The system remote control is usually a blue wire on your decks harness and it is for an amplifier for a sub or other speakers. It sends power to the subs amp when the deck is turned on. You may need to find the wires coming off the antenna and splice them into the red power switching wire 12v on you decks wire harness. Good luck

Actually, there a re a bunch of hits when you Google it.

Here's the answer I found straight from Pioneer:

If your car CD player is a 2006 model or newer:

• With the ignition on and radio OFF,
• Press and hold the MULTI-CONTROL button for 2 seconds
• Rotate MULTI-CONTROL button until display reads CLOCK.
• Push MULTI-CONTROL button up or down to adjust hour and minutes.
• Press ESCAPE or SOURCE button to exit

If your car CD player is newer than 2000 but older than 2006:

• With the ignition on and radio OFF, press and hold the FUNCTION button, until the display pops up, then release the button.
• (If you do not have a function button, use the AUDIO button instead).
• Press the FUNCTION button again until the clock shows on the display.
• Press the UP and DOWN buttons to adjust the hours.
• Press the LEFT and RIGHT arrows to move to the minutes.
• Press the UP and DOWN to adjust the minutes.
  When you've completed all the steps, just press the SOURCE button to exit.

If your car CD player is 1999 or older:

• With the ignition on and radio OFF,
• While holding down the CLOCK button, press the number preset button to set the hour.
• While holding down the CLOCK button, press the number 2 preset button to set the minutes.
• Pressing the respective buttons consecutively or continuously will advance the hour and minute.

For further assistance please consult your user manual.

Here are some other answers from around the web:

Hold down the source button till the unit switches off. Press thefunction button until it says clock. Use the tuner/volume controls tochange the time. Left/right switches between hour and minute. Up/downchanges the actual numbers.The website I'm including has all the old manuals on it if this doesnot work for you. Problem is, you may not know your model # so willhave to click through the links till you see a pic of one that lookslike yours. Hope this helps. I'm stoked that my clock is finally right!

turn the radio OFF with the car ON
then its easy to set the clock.
Most folks try to figure it out with the radio on
and it cant be done with the radio on,

Turn it off. Hold down "func" or "function" until something happens.
Then press the arrow keys still something else happens. When you're done, press "func" or "function" till nothing happens. Turn it on.

the difference between constant and switched 12V is the constant is usually for the clock and memory. it draws precious little current. the switched would be for the radio and amp once the car is turned on. You can use tape but either a wire nut (not the pink ones) or a crimp on cap would be better than using tape.

I have the disc if you still need it

When the unit was in the Mazda, it was run and monitored by the Body Control Module computer. Moving dedicated units from one vehicle to another seldom works the way you expect. https://www.google.com/search?q=pioneer+ca9pa+v6+650+wiring+diagram ..

Four wires ... which four wires.

Hi Mark, please download from pioneer website, or put in a search on google for this models user manual. cheers.

The issue you're experiencing with your Pioneer PD-M40 suggests a potential problem with the disc loading mechanism or the sensor that detects the presence of the disc cartridge. Here are some troubleshooting steps you can try: 1. **Clean the Disc Cartridge and Player:** Dust or debris on the disc cartridge or inside the player may affect proper disc loading. Remove the disc cartridge and clean both the cartridge and the player carefully with a soft, lint-free cloth. 2. **Inspect for Obstructions:** Check for any visible obstructions inside the disc loading mechanism or around the edges of the disc cartridge slot. Ensure that there is nothing blocking the path of the cartridge as it is inserted. 3. **Check for Proper Alignment:** Ensure that the disc cartridge is properly aligned when inserting it into the player. Misalignment may prevent the player from recognizing the presence of the cartridge. 4. **Try a Different Disc Cartridge:** If you have access to another disc cartridge, try inserting a different one to see if the issue persists. This can help determine whether the problem is specific to the cartridge or the player itself. 5. **Power Cycling:** Turn off the player, unplug it from the power source, and wait for a minute or two. Plug it back in, power it on, and then attempt to insert the disc cartridge to see if the issue is resolved. 6. **Test with the Lid Open:** Power on the player with the lid open and observe the disc loading mechanism as you insert the disc cartridge. Check for any unusual movements, sounds, or signs of misalignment. 7. **Lubrication:** If the player has not been used for an extended period, lubrication on moving parts may have dried out. Consult the user manual for recommendations on proper lubrication or contact Pioneer customer support. 8. **Contact Pioneer Support:** If the issue persists and you've exhausted the troubleshooting steps, it may be advisable to contact Pioneer customer support or seek assistance from a qualified technician. There could be an internal issue that requires professional attention. Always refer to the user manual for your Pioneer PD-M40 for model-specific instructions and recommendations. If you don't have the manual, you may be able to find it on the Pioneer website or by contacting their customer support.
