So this morning I decided to replace the battery on my Ford C Max. I replaced the battery no problems whatsoever and went to start the car and the car came up with a number of faults. The first fault is steering lock engaged turn steering wheel, Second faults engine malfunction service now, third fault parking aid malfunction service required. I then decided to do the self diagnostic test, the following codes came up, C151_00, C140_00, C 200_00, C1 21_00, 1607_82, C1 31_00. During the self diagnostics, I checked the battery voltage on the new battery which was around 12.2 V. I have also noticed that the steering lock is not engaging. Any assistance in solving my problem would be greatly appreciated.
