Question about 2004 Dodge Ram 2500

2004 dodge 1500 - no power for Trailer brake lights/signal lights

Towing package on vehicle but no power for brake or signal lights for trailer only. Truck itself is fine. Fuses are fine, read some articles that the Integrated Power Module (IPM) may need to be reset but at 70,000+ miles that isn't under warranty.

SOURCE: trailer light hook up for towing

By an inline adapter, that goes between your main harness & tailights connection, and accepts flat 4 or whatever you require for trailer. Most automotive places have them, and perhaps even walmart.

SOURCE: reset code trailer towing may set code gm 4l60E

Diagnostic trouble code P1870 (Transmission Component Slippage) is a General Motors-specific code whose set parameters are determined by transmission type and engine size. The PCM monitors and compares engine speed to vehicle speed after the converter clutch has been commanded ON in either high gear or Overdrive. Should the expected rpm ratio exceed predetermined parameters, DTC 1870 sets. And upon doing so, the PCM elevates the transmission main line pressure and stops converter clutch apply.

Once the vehicle has made it to a cruise state, the PCM then begins to monitor the vehicle's cruise ratio. If at some point the transmission begins to slip, P1870 sets and line pressure is elevated in an attempt to stop any further slippage and prevent further damage. This would explain why DTC 1870 Ls often accompanied by a complaint of a hard 1-2 up shift.

When this code sets, it could have any number of causes, ranging from the sump running low of fluid to a malfunctioning torque converter. Take a GM 4L60-E transmission, for example. When it's in Overdrive, the forward clutch and the 3-4 clutches are applied, as well as the 2-4 band. Now add the converter clutch. This is what the PCM monitors at cruise. If the ratio breaks away, the cause could be any of three components, the hydraulics that operate them or the electronics that control them. Fortunately, experience has shown that in most cases, the cause can be traced to some form of converter clutch failure as a result of valve body concerns. With GMs 4L80-E transmission, this code has usually been the result of a cracked converter clutch piston.

Put a line pressure gauge ($55 shipped on Ebay, or visit a local trans shop) on the pressure test port and go for a drive to verify proper line pressure. Base pressure at idle in P,N,OD should be around 70psi and around 140psi in R. Max line pressure should be at least 190psi at WOT in 1st or 2nd, 225psi is optimum. If base pressure is low, trans or pump is worn out. If max pressure is low, check EPC solenoid. If reverse is slow to engage, and line pressure does not come up to at least 130psi in reverse, replace the boost valve with a Transgo 0.049" - 0.500" boost valve (easy fix in pan), and replace the servo with an upgrade servo from a Corvette 4L60E. This will give you a more firm shift and address the DTC 1870 which is common to a weaken Boost valve or faulty EPC valve.

SOURCE: 2001 F150 supercrew w/ factory towing - No tail lights on trailer

Not sure which fuse you checked.
The Engine Compartment Fuse Panel ( Battery Junction Box / BJB ) is where the fuse is for the trailer tow adapter parking lamps.
Fuse # 5 is the fuse for the parking lamps, and the reversing lamps.

Next is the trailer tow adapter park lamp relay. This is what BJB Fuse #5 feeds, and the coil is operated by the truck's parking lamps. This is also in the BJB, Relay 201, it is the 1/2 size relay.

Not sure what you took a resistance reading from on the trailer tow adapter.

If you want, you can pull the trailer tow park lamp relay, and jumper the normally open contacts, which should provide power at the trailer tow adapters, regardless of the truck's lights.

Trailer lights come on when van lights are on but turn signals don't work.


The turn signal bulb circuit on the trailer MUST match the towing vehicles turn signals. Example: Tow vehicle turn signal light is the same bulb as the brake light, then the trailer must match. If the tow vehicle has a separate turn signal (amber bulb located away from the brake light) then an adapter is available that will send the correct power to the trailer so everything works correctly. The adapter can be found an auto parts stores, RV supply stores and some truck stops too.

Where to find the wire going to the trailer towing plug for the braking.


As far as I know, your trailer towing package does not include a circuit for trailer braking. These packages normally only supply taillights, brake-lights, and turn signals.
RV sales and service dealerships should be able to help you.
God bless your efforts.

2003 Dodge Ram 3500 left turn signal problems / trailer


Well let me shed some light on this issue. I have the same problem. Trailer connection from truck does not have power to left turn signal and left brake light. I just got back from the dealership and $100.00 labor charge. My problem is the TIPM (Fuse Box for short) and FCM (little silver module hooked to the Fuse Box on the left hand side of the fuse box). $910.00 for the parts and Chrysler doesn't have any in stock. 4-6 weeks to maybe fill a back order. I am currently researching an alternative way to fix this issue. I will let you know.

Trailer lights


This is the tow vehicle end. The brown wire ( #6 terminal) is the one to concentrate on. It must have a bad connection either in plug at bumper or wherever mounted, or follow it back toward front of vehicle, and will likely have a connector just behind bumper area, or up near frame as well. Best thing is to use a test light ($5-$10) and probe toward front until you get power showing, then work back to plug to isolate. Begin by checking terminal at plug with blinker on, if no flashing of test light, find brown wire on back of plug & test there, and keep going toward front of truck, especially concentrate on connection areas.

Check the owners manual to be sure of the location of the trailer fuses. Most have several locations for the fuses. Other than that, look for a loose or corroded connection. Also check http://www.etrailer.com/faq-wiring.aspx.
