[QUOTE="DieselDog, post: 1422458, member: 26353"] Most common cause we see is the yellow CDC09 has a small split in the insulation around the wire this will allow corrosion and damage wire. The circuit lines with the main B+ cable down and around the lower engine from passenger to driver side there is a location on the passenger side where the wire is routed at a 90 degrees bend to go up towards pcm. The bend is just below in front of engine mount just follow B+ cable you will see the bend, other location is just below waterpump driver side common at the bend and if water pump has been replaced sometimes the circuit will get cut or pinched during repairs. If you can pull on wire near those locations see if wire breaks if it does then just repair. it does not need to look the same you can route different just make sure it doesn't chafe or get caught in belt drive system. Best splice method is solder joint and if you can use marine heat shrink keeps moister out of the wire . Or fastest easiest way is to just overlay circuit from Generator pin 2 to the PCM pin 53. If I remember tomorrow I wil download some pictures of locations to help with isolation of open in circuit. Sent from my SAMSUNG-SM-G930A using Tapatalk [/QUOTE]
