Computer Reset After Changing Battery?
I just changed the 12 volt battery on my '13 C-Max for the first time. It was a little bit of a challenge due to no mechanical latch on the back hatch door, but it worked out. The dealer has suggested that I bring the car in to have the computer reset (1/2 hour labor). I understand that some high end cars do require that the onboard computers be synced with an individual battery, but is that really necessary on a C-Max? What are the risk if I don't do that?
OK, I reset my 12 V battery age from 753 days to zero days by doing the following:
1) Placed car in ACC mode by pushing start button without foot on brake. Again, it may also work in ready to drive mode. In ACC mode, the DCDC converter does not charge the 12 V battery (set point voltage is 10.6 V). The DCDC converter
sets the voltage at 13.0 V which basically is a float charge to keep the 12 V battery from discharging.
2) Operated high beam switch 5 times.
3) Pumped
