XPR XPR4550 Issue

[m6oef]

Hello everyone. I have a problem with my XPR4550. Ive recently powered it on and just changed the codeplug by adding a few new zones.

This is nothing I haven't done many times before with out a problem.

This time when I installed it it seemed to finish the codeplug install and the radio powered down straight away which its never done before.

I then turned it back on but its simply just powering down again.

Is this due to the codeplug or firmware or could this be a physical problem with the circuit board? I have tested the power lead and fuse and all is fine. Even made sure it wasnt an earthing issue and replaced the power lead still doing the same.

If it is a firmware or codeplug problem how do i keep the radio on whilst replacing the firmware or codeplug?!

Many thanks

Did you enable ignition sense?

its on follow ignition only however the radio is connected straight to the battery not via anything else. I dont think ive ever touched the ignition settings. This was the codeplug that ive been using for ages. Just every so often changing some zones or frequencies. If follow ignition only ignores the power button the power button would not work at all? Im still able to turn the radio on even if its for a second.

Complete shot in the dark....yank the fuse and press power button to try to turn it on. Then replace fuse and turn it on.

Also, try to power it up with CPS running and cable attached, btw, are you using front or rear for cable?

To add, what CPS are you using? I thought I saw a MTN about using the newest version with older firmwares/CPs written by older versions of CPS. And, also, are you reading the radio to edit, or editing a saved CP. Shouldnt matter, but this is Moto ro la after all.

Have you applied power to the ignition sense wire?

yank the fuse and press power button to try to turn it on. Then replace fuse and turn it on - I have tried that already and still just shuts off.

try to power it up with CPS running and cable attached, btw, are you using front or rear for cable? I will try that and im using a sep kit at the moment so front. but will try this with the radio put back together!

Im reading the code plug adding to it then re uploading the same one just changed.

Have you applied power to the ignition sense wire?

No not yet. Im in the middle of either trying to make one and finding which pin to put it in or buying an actual pre made one from the states.

If you have it set for follow ignition only, you have to use the ignition sense wire. Change that setting in the CPS and see what happens. Ignition sense is pin 25.
