I have two ICOM clones whos failing on KLINE. DCAN works perfectly. What could be the problem?

Did you change the Samsung NAND?
Change it and restore firmware.
Should work as spomeone has reported the same issue as you and it worked after that.

I need only to change Samsung NAND ? Not any programming needed ?
Can I solder new NAND and then restore FW ?
Thank you

Yes that’s correct

Today I ordered 2 Samsung NAND.
I will try and let you know.
Thank you

I have two ICOM clones whos failing on KLINE. DCAN works perfectly. What could be the problem?

KLINE worked after purchase?
1.There was a marriage and installed 3.9kom instead of 39kom
2.Another reason can be in inverters

Hello ferrum,
I change micrel on my ICOM and the problem is always there.
LAN led never blink, and ICOM not visible in Ethernet connection.
It boots correctly, SYSTEM LED blink and then stays ON.
Can you help me, please ?
Thank you
Bests

Have you checked the lines from the LAN connector to the transformer and from the transformer to the miсrel?

Do not rush to change nand, this can not affect what does not work!

Yes it worked for few years. Checked that resistor and it was ~37k, o it should be ok because it is 5%. After 3 years of using they have started to fail to read KLINE sometimes and about in a month using like that KLINE was dead totally. Check KLINE with other ICOM and it was ok.

Yes 37k this is normal.
There is no unequivocal answer on your question, you need to check a lot.
Сheck the diodes and inverters.

After reading this thread I finally decided to try and fix my ICOM clone that would not connect to K-line vehicles. It had a second issue where it would connect to D-can vehicle's but not with ethernet on the F-cars. I replaced the inverters shown in post #25 with no change. In post #4 the pcb had the IC marked VP234 (SN65HVD234D) removed so I figured it's cheap and easy enough to replace. After replacement of the VP234 chip my ICOM would properly connect to several K-line vehicles but lost KL15 voltage readings on D-can vehicles. I re-checked my work and found a solder connection between the small resistors in-line beside the VP234 chip. After removing the excessive solder my ICOM works properly. Not sure why the VP234 had an effect on the K-line as it seems to only be for the D-can...hopefully this info helps someone.

changed micrel 2 times, after change worked for some minutes (in my opinion, heat effected bad component...). Next day same problem, status green, lan blinks green, computer gets ip, but no packages recieved, no icom in itool detected... What to look next - mpc5200cvr400b?

Hi,

can someone helpl with icom a2 connection issues? Used for about 2 years and everything worked fine. Couple days ago tried to connect with e-sys and got error. Rheingold, inpa, ncsexpert works fine. With enet cable i can connect via e-sys without problems. Did self-test and got WLAN failure. WLAN is for WIFI? because I don't notice ever that WLAN is blinked. My icom doesn't have wifi. Maybe someone know how to fix that connection issue?

Thanks
