My JPE is very stable due to clutch troubles and fuel tank leakage were fixed, I was thinking. Maybe I'm not sure, this was flagged for the turning points. An ECU of the JPE' uses an EMS EM-70 and communication between an EMS and a PC couldn't be successful. So I retry to find out the cause of communication error from today morning.
LEDs on LAN port couldn't turn on or/and flashing even the EMS connect to the PC. LAN port had orange LED and green LED, both of LED didn't change condition.
Of cause if I want to check the status the LEDs, should open a scuttle. So situation doesn't change I took off the EM-70 from the JPE and open cover check the PCB, so all IC devices are surface solder with this normally couldn't replace broken IC device if I could find it. Maybe EMS EM-70 in LAN communication function is malfunctioning.
And malfunction IC is surface solder therefore, replacement of IC device isn't easy for me. What can I next step?
Repair of the EMS by maker in Austraria. But maker is likely bankruptcy because company name changes on the web site. So supplement and the after service will be confused in the future. Although, repair of the EMS is a lower burden than maker change, but continuously for maker support is unclealy.
Think like that, this is chance of change an ECU maker to anther company isn't this? I'm in hesitate for exchanging other ECU maker.
