IPKs Schematics

Hogwarzt · 6th September 2019, 17:48

Hi All,

Does anyone have schematics or know what the differences are between YAC003850 & YAC003890.

I converted the 850 petrol to an 890 diesel and all is good apart from the sounder not working for the reversing sensor. PCB look the same? Any ideas? I can only assume a minor PCB is difference??

Regards
Rich

No differences between them, if the sounder works in one and not the other then its a duff sounder.

Hi Phil,

This IPK was a brand new unit, sealed in box. Was there an issue with sounders? In a way that's good news …. I think. Good to hear from you!!

Hi Rich, I take it you simply swapped the 93S56 from the old to the new?

There is certainly no other differences between a ZT petrol or diesel version, if you need to see if the KMB sounder is ok, then a quick way is lights on, door open, as the same piezo sounder is used for PDC as lights on warning

Hi Brian,

That's basically what I did but programmed a new device.
Then fitted to new ipk.

Screen started playing up on the old one.

I have a couple of old units that could be doners regarding the sounder.

Quick uodate

Tested sounder in situe on bench, not working.
Removed sounder just by removing the rear cover to access solder joints. CONFIRMED DEAD!

Replaced with a doner ipk sounder and all is well. I noticed a couple of electrolytics looking a little odd and tops bulging. Replaced those just in case.
