Hello,
I am new on this forum and have regularly browsed the forum for advice .
I am having problems with a Fiat Grande Punto 1.4 8V I bought about 7 months ago (second hand 2009 approx 36,000km). I hope somebody can help me.
Broke down several times past December: car stalls - engine still runs but no possibility to engage the gears - err msg on dashboard <fuel cut-off> and <unavailable>.
Took car back to dealer who 'cleaned and re-routed' the CAN cables. Problem seemed to be solved until two days ago (about a month after repairs) when the problem reappeared. In the meantime I purchased a set of cables and the Multiecuscan software so I can do my own diagnostics. The errors in the multiecuscan seem once again to point to the CAN network and its cabling. Here are a few excerpts from the error messages from the different modules:
ECU: U0001 - C-CAN line error / U1700 - CAN network (NCM - NBC) / Error in communication between engine control unit and Body computer. Check CAN lines.
STEERING: U0001 - C-CAN line error / U1700 - Communic. with Body Computer (NBC)
GEARBOX: P0710 - Temperature (from CAN) / U1706 - CAN Network (NCR - NFR) / Error in communication between automatic transmission control unit and ABS/VDC brake system control unit. Check CAN lines.
ABS: U0001 - C-CAN line error / C1221 - Engine control (NCM) / The Engine Control Node fails to transmit data on CAN correctly.
DASHBOARD: U1700 - No Body Computer / U1701 - Engine control (NCM) / U1711 - NCR Node absent
BODY: U0019 - B-CAN line / The CAN data communication line (Controller Area Network) between different vehicle ECUs does not work correctly. Check the harness between the ECUs for opens, shorts and weak connections, and ripple free power and good ground supplies to the ECUs. / U1702 - Electric Steering (NGE) / U1701 - Engine control (NCM) / U1711 - Automatic Transmission (NCA-NCR) / U1706 - Brake system (NFR)
I compiled all the logs from the different modules in one txt file and attached it to this message.
In spite of these problems being intermittent it is really uncomfortable when I get stuck somewhere, usually in the middle of the road with no way of moving anywhere since the gear does not engage. So yesterday I decided to travel with my laptop and ELM cables hoping that I would be able to clear the error codes on the spot and get going again. I broke down once again but could not connect to the ECU while the fault was active and the car stalled. I gave up after more than an hour and got a lift back home. Later that evening (about 4hrs later) I went back to the car and this time I could get going although with a few error codes on the dashboard (EOBD light was on: engine control system failure). I reached home and scanned all the modules for error codes (see above).
My main question is: when the car stalls like that, can I use the Multiecuscan to clear codes and get going again? Or is there another way of 'resetting' the ECU?
