I have a issue regarding communication/connection with my SQ6 ECU.
It was bought already 2012 but has been lain in the box and not used, until now. I have build an engine wiring loom and a Ethernet wiring connection, but I can not connect to the ecu with PI Caltool or DescPro. The Ethernet connection seems to work. The computer says connected and the green and yellow led indicators on the Ethernet port blinks when the ignition is turned on, but DescPro and Caltool says no device. I have also tried to ping the ECU but it fails. The ecu puts out 5volts on pin 65 to the sensors so it has current and seems to be "alive".
Can it be the internal battery that is out of power? Do you have any other test I can do to be certain?
The ecu came with a disc with DESCPro 01P-099063 Pectel ECU Software Batch 147274. And I can pm you the serial number on the ecu.
I would prefer to use Caltool instead of DESCPro. Can the ecu be updated to the latest sw/firmware so I can run the latest Caltool version?
Hope you can help me and let me know if you need any further information from me!
Best Regards Johan
