Hi, long term leaf owner, but looking at buying a 2012 leaf a town runabout for my son. We know it has some faults (currently owned by a friend), so I'm trying to work out what we will need to fix before I commit to buying it..
Key DTC faults via leafspy are
C1111 - ABS pump
C1A70 - Brake control system
There is also
U1000 HVAC CAN, but I'm not too worried about this right now
After a helpful root around the forum, my plan is
1. Charge 12v battery fully/try and swap for a newer battery as a test as I gather low bat voltage can cause odd faults (perhaps the battery from my 2019 leaf will fit)
2. Order some brake pressure sensors (47240AL500) in case they fix the C1A70 issue
3. Check the fuses and supplies to the ABS unit
3. Be prepared to try and track down a replacement ABS pump/valve unit to replace the existing one
On the ABS, should I hear/feel the pump spin up when the vehicle is powered up, or just when the ABS self test kicks in at low speed (5-10mph?)? I suspect I'll need to replace this, but I'd rather not pay for a unit (and shipping to Iceland) only to find this isn't the issue.
On a similar vein, does anyone know what the '>' character before a DTC error code in the leafspy list means (e.g >C1111)? I can't find a mention of it in the user manual. I'm guessing it indicates the error is current/ongoing, as I can't clear these from the system, but it's just a guess.
Many thanks in advance from an unseasonably warm Iceland
