Thread is intended to be informational to other owners. I have a issue with my Titan XD that started on 12/27. After driving in 2wd for a few mins to as long as 15 mins, a 4WD error warning message will pop up on the display. When this happens the ABS, Traction Control and ATP lights will come on as well. While the truck is in this state, I have no control over going in and out of 4hi or 4lo so truck is basically stuck in 2wd mode. Truck was at the dealer recently from 12/30-1/2, during this time, the dealer installed a software update and performed a hard reset of the 4WD system which was recommend by Nissan. Service Manager stated that if it continues contact him and he will document each insistence of it happening. On 1/4 the error returned, I talked to the service manager and he is getting with his diesel tech and Nissan this morning to research the problem some more and will get back to me this afternoon. The codes the dealer pulled are: P2509-00 (ECM/PCM power input signal), C1118 (4wd system), P182A (HI-LO Position Sen), 47 (axle/differential) Anyone else having this problem and What was done to fix it?
