I took my truck to the dealer this morning to finally get my rear fuel filter heater turned on.
They did the following while they had the truck:
TSB 14-005-13 BCM reconfigure for the heater
TSB 18-10-14 DEF control unit update
TSB 18-052-13 PCM reprogram for Aisin A/TAND
TSB 08-001-14 ABS reprogram
TSB 24-001-14 HVAC update temperature control
TSB 21-15-14 TCM module inspect and reprogram
TSB 08-20-14 Amplifier module inspect and reprogram
The truck still runs fine with no CEL and no codes found by dealer. I hope this takes care of software fixes for awhile... and the heater does have voltage now, I checked!
