Customer Question

Hi have a 2011 Cayenne. Change the battery for a new one and inflate the tires that were low pressure. It was working fine after a day it started showing a ABS, PSM, Four Drive Overload and Brake messages all at once. I turn off the PSM system and seems to drive OK, but the messages still shows.
JA: How old is the battery? And have you tested it with a voltmeter?
Customer: The battery is a gel new. Yes it was tested
JA: Are you hoping to fix this yourself? What have you tried so far?
Customer: Trying to fix it my self with the owners manual, but nothings seems to be the right solution. I the original owner.
JA: Anything else you think the mechanic should know?
Customer: That's it. The only thing it occurs to me, that the wheel sensors are not working.
