Last December RF TPMS failure indicated on dash display. Purchased Relearn Tool and went through relearn process. LF tire acknowledged learn. Got to RF and no response. Dash display then showed all four TPMS failures. Still in that condition today.
Mid-January upon starting truck, ABS and Stabilitrak lights came on and cruise control no longer functioned. This would happen more often than not. Tried hard reboot by disconnecting battery overnight. Warning lights/cruise symptoms went away for about a week, then came back. Seemed to occur more often the colder outside temp was. these symptoms went away mid-April.
Truck sat for the month of February. Went to start truck and both key fobs no longer worked, also auto door unlock in park no longer worked. Unlock truck with key and alarm goes off.
Replaced key fob batteries and RCDLM. Checked power and ground at RCDLM also for shorts on Rx & Tx lines to BCM. Checked BCM P218 ground post. Am I looking at possible BCM failure? Thanks.
