Volvo ew145b prime fault code 128 sid 232 4 ECU error Machine shuts down after half to one minute of start. Sometimes also appear 128 psid 97 7 . The serial number for vecu is mentioned in the picture. Any help will be greatly appreciated!
Good start...good info to work with...these guys will have some good ideas.
232-4 Detection conditions:The engine control unit (E-ECU) registers: that the voltage is below 4.5 V (EA7)(EA11) Looks like rail pressure sensor 5V ref shorted to ground. 97-7 Rail pressure relief valve stuck closed- I suspect because ECU cant read pressure when short to ground occurs.
Thank you so much for the reply Innocent bystander! I think you wants to say that the signal wires are somewhere shorted to grounds?
