Expert Answers about Toyota Tundra

• No Trailer Stop or Turn Lights On a 2011 Toyota Tundra
• Have you checked the relays in addition to the fuses? If not then this would be the next thing I check. You can swap a relay out that you know is working for one that is not to do the above. I will say that the vast majority of cases with this issue will be attributed to a blown fuse so make sure to inspect the element inside the fuse carefully as it is not always obvious it is blown. Once this is done your next best option would be to trace the wires back while checking for breaks. If...

• Tekonsha Prodigy P3 Brake Controller Shows Warning Output Shorted No Brakes with New Breakaway
• The "Warning Output Shorted No Brakes" error message on the Tekonsha Prodigy P3 Trailer Brake Controller part # 90195 per the manual can be caused by one of two things. I have listed these for you below: 1. Detects brake output wire shorted to ground. Short during idle condition. 2. Use of some test lights or non-Tekonsha testers can cause this problem. Therefore, it sounds like you have a short in the usually blue brake output wire or it is installed incorrectly. This can an issue on...

• TPMS Light On and Still Calibrating After Installing Redarc Brake Controller On 2018 Toyota Tundra
• I actually just recently ran into a similar issue with a Redarc brake controller on a Toyota vehicle. The issue was the integrated diode Redarc uses on the plug-in-play harness not allowing for 12 volts to be sent to the stop light switch circuit. I bet if you tested the stop light circuit on the tow package port with the brake pedal applied you would get less than 12 volts. The fix is to use a new harness, the Curt Custom Wiring Adapter part # C51455 with Redarc Tow-Pro Wiring Adapter...

• Troubleshooting Installation of Curt 4-Pole Wiring Harness C55378 in 2002 Toyota Tundra
• The two wiring harness kits you referenced, Curt # C55378 and Tekonsha # 118378, are both correct fits for your 2002 Toyota Tundra. Both of these kits are multi-part harnesses that include the required fuse/fuse holder and the installation of the Curt kit in a 2002 Tundra is shown in the linked video. The troubleshooting steps I suggest are to double-check that all connectors have no bent or damaged contacts, that they are fully seated together and that the ring terminal on the harness...

• Trailer Brakes Lock Up When Connected To Trailer Using 6 to 7 Pole Adapter
• The issue you are having with the trailer brakes locking up as soon as the trailer connector is plugged in has to do with the pin out of the trailer side trailer connector in relation to the adapter. The most likely problem is that the battery charge line is crossed with the brake output circuit. In order to fix this you will simply need to just swap out the two wires on the back of the trailer side trailer connector or you can just rewire a new trailer connector on the trailer using the...

• Troubleshooting Brake Output Circuit that has Voltage all the Time
• The brake output circuit of your 2008 Toyota Tundra should not have 12 volts without the brake pedal pressed or the manual override of the controller slide. This would indicate that either the brake controller is bad or you have a short on your trailer connector wiring. I would first check the back of the connector for corrosion or exposed wire and fix as necessary. The 12 volt accessory circuit may be shorting out to the brake output circuit. If that doesn't fix the problem you will need...

• Troubleshooting NC Message on a Tekonsha Primus IQ Brake Controller
• I would be happy to help you troubleshoot the problems you are having with the Tekonsha Primus IQ Trailer Brake Controller item # TK90160. You will first want to check your Tundra's 7-way connector for debris, corrosion, and any faulty wiring connected to it. Afterwards check your trailer's 7-way for the same thing. If you're still getting a N.C. code on your controller I recommend verifying the brake controller wire has been properly connected and there isn't any damage or faults between...

• Troubleshooting Brake Controller and Poor Braking on Trailer Towed by 2018 Toyota Tundra
• The three main things that could be causing your issue are: 1) Insufficient brake adjustment. The adjusters should be turned 'out' until you can't turn the wheel by hand when it's jacked up off the ground. Then the adjusters should be backed off by 10 or so clicks so there's still a slight drag from the brake shoes. 2) The brake shoes should be broken in correctly or 'burnished'. This is done by applying the brakes 20 to 30 times to decrease the speed by 20 mph. Example, once reaching...

• Troubleshooting Prodigy P3 Without a Display
• We have heard of this issue before with the Prodigy P3 Trailer Brake Controller # 90195. What Tekonsha has told us is that to remedy the lack of a display you will need to reset the brake controller. To do this you will need to unplug the trailer, and then unplug the harness from the controller and wait about 30 seconds or so. After plugging it back in the display should return.

• Troubleshooting Turn/Brake Signals on Trailer with New 4-Way and 5 Wires
• It sounds like your trailer has a wishbone wiring setup that uses a separate running lights circuit wire (brown) on each side of the trailer. In terms of standard trailer wiring colors it appears that you have wired the new 4-Way correctly, the issue might be that your trailer simply doesn't use standard wire colors for its lights. This can happen on older trailers that have maybe had a couple owners or even new ones that were the victim of some "creative" wiring at the factory. Determining...

• Troubleshooting No Power From Converter Box on Reese Wiring Harness on 2002 Toyota Tundra
• Based on the steps you have already taken it sounds like the converter box is bad which means it will need to be replaced, not opened and serviced. The only thing I'm not sure about is what wiring you specifically have. From what I could find it doesn't look like there is a plug and play 7-way for the 2002 Tundra. This leads me to believe that you have a 4-way wiring harness plugged into the factory port with a 7-way adapter added on. If that is the case, you only need to replace your...

• Are Weight Distribution Systems Supposed to be Noisy
• Weight distribution systems do typically create some noise whether it is creaking, scraping, or even clunking. This is normal and is a result from the metal on metal contact. If you are using the Pro Series system # 49570 or a similar system with a friction sway bar like # 83660 it could be that it is not adjusted properly (too loose or too tight) and that might be the noise you are hearing. I have included a link to a video showing installation of this system so you can verify everything...

• Factory Trailer Connector on 2006 Toyota Tundra Has Running Lamp and 12-V Circuits Reversed
• We see this every now and then with Toyota and Nissan trucks for some reason. It sounds like your running lamp circuit and the 12-v feed are reversed. The easiest thing to do is just rewire the connector on the truck, so your connector will be correct in case you ever need to tow anything else. I'll link to our trailer wiring help article, which will show which terminal on the back of the truck's 7-way serves which purpose.

• Meaning of Flashing OL Code on Draw-Tite Activator Brake Controller
• The OL code on your Draw Tite Activator # 5504 has a different meaning depending on if the trailer is connected or not, but in both situations it indicates an overload or a short on a wire. If the OL code is flashing without the trailer connected, then the short is in the Blue wire from the back of the controller. You'll want to trace this wire starting at the brake controller back to your vehicle's 7-Way to find the damaged or pinched section of wire that is causing the short and repair...

• After Plugging in P3 and Harness 3040-P on 2014 Toyota Tundra Brake Controller Does Not Turn On
• You should not have to run the extra ground wire on brake controller harness # 3040-P to the negative battery terminal on your 2014 Toyota Tundra. You will need a clean bare metal location though. No paint or aluminum either. A bare steel surface. Use a circuit tester such as # 3808 if needed to test the black wire after the controller is plugged in. If there is power on that black wire but the controller still does not turn on then there is something wrong with the controller and it...

• Troubleshooting OL Error Code On The Tekonsha Primus IQ Brake Controller
• Generally the OL error code indicates a short in the trailers brake circuit wire. We recommend inspecting this wire all the way from the trailer plug to your brakes and make sure there is no damage. Also inspect your trailer connector and plug for any corrosion or damage. I will say that if this were the issue, we would expect to see that error at any speed, not just at speeds lower than 15 mph. You can test if it's the controller by cutting the blue wire from the controller. If the OL...

• Troubleshooting Towing Trailer with Weight Distribution Where Vehicle Suspension Still Sags
• First you need to determine the loaded tongue weight of your setup and be sure you are not exceeding the tongue weight range of the part # RP66073 which has a tongue weight range of 400-800 lbs. You could easily be exceeding that with your trailer loaded as tongue weight is typically 10-15% of the total weight of the trailer as it is ready to tow. I did attach a video that shows how a similar Straitline system installs and sets up for you to check out. I do think you need to go with higher...

• How to Get the RhinoFLEX RV Sewer Hose w Swivel Fittings to Fit in a Bumper
• I spoke to my contact at Camco and he said that if the lug end of the part # CAM39761 doesn't want to fit into the bumper of your trailer your best option would be to grind down two of the lugs and the hose would then fit.
