I just purchased this 2004 Titan a month ago and was driving then all of a sudden the service engine soon light came on. I took it to the auto parts store and had the codes read. All the codes that appeared were: P0037, P0057, P1614, B1073, B1023, B1019, C1108, C1187, and C1155. I have researched the P codes and the only issue I am having is finding the part for the B1073 the parts store told me this code is an airbag module but when I look online I can not find parts for this or any of the B codes. Any help would be greatly appreciated if anyone has ran into these issues and has any info on where to get the parts. My truck is a 2004 titan with 138K miles, the service engine soon light, abs, b-lsd, and airbag lights are on.
