Hello Everyone,
I have a 2014 3door Punto 1.2 petrol, and it has been a great car, has taken me to southern Spain and back with no problems, and really never let me down.
Last autumn however the alternator was changed after cutting out in town.
Recently the ABS light came on, and when I read the codes with Multiscan the error pointed to the wheel sensor, which was changed. All good for a week, then ABS light came on and stayed on. Local mechanic chased down a broken wire, repaired it, and happy days, all seems fine.
On a recent run I noticed that battery voltage was dropping, as shown by my cigar lighter connector (gives me extra sockets for satnav etc) which has a volts display built in. Voltage went down to 11.1 when car began to shut down. New battery was fitted which just got me home, with the voltage dropping all the way. There was no warning light on the dash.
After a couple of restarts, voltage went back up to over 13 for a day, but now it has gone back to no charge, with voltage dropping as before.
The garage checked and cleaned earths, wiring etc. and will extract the alternator and get it tested next week. In the meantime I am trickle charging the battery overnight so am able to drive locally.
Multiscan gave the following codes before the ABS wiring was repaired:
Scan vehicle for available modules and check each module for errors...
Engine / ECM
Magneti Marelli IAW 9GF CF6/EOBD Injection (1.2, 1.4)
ISO Code: 7A 07 6D 8C 4F
Errors found:
P0621-15 - Alternator
Body / BCM (Body Computer Module)
Body Computer Delphi (199) MY09
ISO Code: 40 83 51 08 F1
Errors found:
U0019-01 - B-CAN line
B1009-16 - Battery voltage
ABS / ABS/BSM (Brake System Module)
Bosch ABS 8 ESP (2)
ISO Code: EC 07 08 07 57
Errors found:
C0034-01 - Front right wheel speed sensor
C1200-16 - Battery voltage
Electric Steering / EPS (Electric Steering Module)
Delphi Electric Steering (2)
ISO Code: 31 83 16 08 A7
Having read through various explanations of the P0621-15 I shall try running a jump lead from the negative battery terminal to earth to exclude bad earth from the possibilities. Main Fiat is 2 hours away but over the phone said it could be the BCM (mentioning 800 euros).
Is there anything I can do with Multiscan to narrow the possibilities down?
Thanks in advance,
John
