2010 Nissan Titan Trailer Fuse Locations

This 2010 Nissan Titan came in with the complaint that the trailer lights did not work. A quick test showed just that, no power at the tail, turn or stop lights.

The fuses are located under the wto covers behind the battery.

The covers have latches that have to be depressed in order to remove them. Also note the extra notch at the bottom right of the cover. When reinstalling the cover it need to be oriented as shown in the picture below.

This is the fuse for the trailer turn signal and stoplight controls. Power on one side.

None on the other so the fuse is blown. A new fuse corrected the problem with no turn signal and stoplight signals for the trailer.

The tail light fuse for the trailer was a good bit harder to find. It is actually located in the IPDM E/R (Intelligent Power Distribution Module  Engine/Room). The IPDM has to be partially removed in order to access the fuse. There are latches on either side that have to be depressed so that the IPDM can be lifted up.

The trailer tail/park light fuse is one of the two red 10 amp fuses in the picture below. Sadly I did this repair several days ago and I do not remember if it was the one on the bottom or the top. Hopefully someone will add a comment to clarify this.

I used a long screwdriver to hold the IPDM up while I changed the fuse with a long pair of needle nose pliers.

The IPDM is back in place and it’s cover is also reinstalled.  The front cover is yet to be installed but the next picture shows the relationship between the two boxes.

The two fuses that were causing the problems. Actually they were just a symptom of multiple shorts on the trailer. Notice the design of the fuse on the right. If at all possible avoid this design. They sometimes do not blow at the proper amperage level and can cause harness damage. Most of the time the amperage rating is stamped into the plastic and not printed in white.

I know it is very hard to tell in the next picture but the red led’s are illuminated.

I also wanted to point out that this type of connector will help diagnose if the basic circuit is there without the use of a test light. It is not full proof though. If the ground is missing the led’s will not work even if the power circuit is present.
