You're best off consulting the service manual (https://www.nissan-techinfo.com/find.aspx?dept_id=10
To diagnose the problem properly, you will likely need to read the DTCs. I can see some listed relating to wheel sensors on page BRC-57 of the '13 Leaf service manual. Page BRC-45 says
• A malfunction is detected in the VDC function, TCS function, ABS function, EBD function, brake limited slip
differential (BLSD) function, or brake assist function of the ABS actuator and electric unit (control unit).
• For the relationship between warning lamp and DTC, refer to BRC-57, "DTC Index".
Thank you cwerdna I will start digging into that service manual.
I did purchase a Bluetooth 4.0 LE OBD-II and got LeafSpy Pro, and read the DTCs.
1. Assuming the "Ok" lines are not errors, does this really mean that I have 10 trouble codes present on my car??? Ouch. I wonder how many the car lot knew about and just cleared before they sold me the car.
2. Why do some of the lines have a ">" before them and some do not?
