ECU errors and help me learn FiatECUScan
Finally connected to my ECU today and need a kick start from you guys.
First I got two FATAL errors and no indication when they occurred. I'm not seeing and warning lights on the dashboard. (Details below)
I thought I could modify some things about my alarm system (set siren ON, because I never hear the horn when I lock the doors, just lights and beep from console). Do I need the full version?
I think my ECU is this one, but who knows? How can I make sure? Anyway, there is no "ISO error" and monitoring works properly except odometer is different from what I see on the dashboard.
ECU Bosh Motronic ME7.3.1
====Details of Errors====
P0443 – Canister Purge Valve : No Signal : Fatal
Anomaly on the circuit of the canister solenoid valve. Check:
1) supply to the valve
2) continuity and the insulation of the control wire from the solenoid valve to the ECU
39 valve efficiency
The reason for this fault is that ECU did not receive signal from the sensor. The fault is present now. Take appropriate action to fix this sensor fault. Dashboard warning light was not activated for this fault.
P0325 - Knock Sensor : No Signal : Fatal : Light ON
The ECU does not receive correctly the signal from the signalled knock sensor. Probably the harness is interrupted or a SC is present, or the sensor itself does not work correctly. Check the harness and connections condition and check the sensor functioning by means of an oscilloscope or a voltmeter in V/PEAK by beating on the sensor clamping screw.
NOTE: it is necessary to comply with the driving torque of the sensor since an improper torque may alter the sensor correct functioning
The reason for this fault is that ECU has received very low signal from the sensor. The fault is present now. Take appropriate action to fix this sensor fault. Dashboard warning light was activated for this fault.
so thanks for your help in advance
