Expert Answers about Toyota RAV4

• Troubleshooting Lights Staying On After Installing Tekonsha ZCI Vehicle Wiring Harness on RAV4
• The Tekonsha ZCI Vehicle Wiring Harness # 119250KIT that you installed on your 2019 Toyota RAV4 can be extremely sensitive with regards to the initial setup. Because it uses zero-contact sensors to identify current flowing through each wire, all the steps need to be followed exactly as written in the install manual. If the lights are staying on after initially activating them then this could be an indication that the magnetic sensors were simply installed in the wrong direction. Try pulling...

• Troubleshooting Installation of Curt T-Connector Wiring Harness # C56165 on 2012 Toyota RAV4
• Since you mention that you aren't getting any signal when testing the connector on the Curt T-Connector Wiring Harness, # C56165, for your 2012 Toyota RAV4, I recommend testing the 12 volt power wire right behind the wiring harness's converter box. If there is no power then you will want to trace the wire looking for damage. If you have power on the 12 volt circuit, you can move on to testing the wires coming out of the converter box. If these wires do not show power when the signals are...

• Trailer Hitch Receiver is Squeaking After New Install on a 2016 Toyota RAV4
• Do you mean the right side where it connects to the RAV4 above the muffler? We sometimes see aftermarket hitches rattle against the exhaust but I've never heard of them squeaking. If the issue is caused by the exhaust you can bend the exhaust hanger a little to create a gap. This is the method we generally use to fix the issue. I've also linked an article that explains the situation in more detail. If this isn't the same as what you're experiencing let me know more about it and I'll...

• Solution for Trailer Hitch that Bent in Shipping
• Sometimes hitches can get slightly bent during shipping and this can be fixed by bending the hitch back into place as long as the hitch only has a slight bend to it. If yours isn't lining up I can almost guarantee that is what happened. Some people will use open steps for leverage, vices and even car jacks to apply controlled force to bend the hitch back. You will want to look for flaking paint and physical stress marks on the hitch before and after you attempt to bend the hitch back....

• Troubleshooting Curt T-Connector Blowing Fuse on 2010 Toyota Rav4
• Is this occurring with the trailer plugged in or was it unplugged? If it's happening with the trailer plugged in, the likely cause is a short in the trailer wiring. You'll want to examine the running light circuit, which is usually a brown wire, the right turn/brake which is usually a green wire and the left turn/brake which is usually a yellow wire. Begin at the trailer connector, and trace your way back to the lamps, looking for pinched wires, loose connections, and nicked, worn or cracked...

• If you are getting intermittent power the potential issue with the Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C56165 on your 2007 Toyota RAV4 the first thing to do is take a look at your owner's manual to locate any trailer fuses or relays and ensure they are all there and in working order.

• Not All Trailer Lights Power On with Trailer Connector C55486 on a 2000 Toyota RAV4
• Since the 4-Way end on the # C55486 harness is working then the issue is most likely a ground on the trailer and/or a dirty connector. Make sure the trailer side connector is clean and free of corrosion. Then make sure the main trailer connector is grounded to a clean and corrosion free bare metal surface. Do the same with each of the trailer lights. If you have an aluminum frame, tilt bed, or folding tongue on the trailer then you will need to run jumper grounds from the lights to the...

• Only Trailer Side Marker Lights Work After Installing a Trailer Wiring Harness on 2010 Toyota RAV4
• This sounds like a bad ground either on the wiring harness # 118412, on the trailer or both. First try moving the ground from the wiring harness. Make sure it is attached to a clean and corrosion free bare metal surface. Also make sure that the main trailer side connector is grounded to a clean and corrosion free bare metal surface. Do the same for each of the lights on the trailer. Make sure the trailers connector is corrosion free. If the trailer has an aluminum frame, a tilt bed, or...

• No Stop/Turn Signals with Curt T-Connector Harness On 2021 Toyota RAV4
• The correct Curt T-Connector Vehicle Wiring Harness for a 2021 Toyota RAV4 is part # C56434. If you're having issues with lighting signals, make sure you're testing at the vehicle side with a circuit tester to rule out any issues on the trailer. If there are still no signals probe the wires entering and leaving the converter box. If you have power going in but not leaving you know this is bad and the entire harness would need replaced. If there is power entering and leaving I recommend...

• Trailer Right Turn Signal Does Not Work on a Trailer Towed by a 2010 Toyota RAV4
• If it is only the right turn signal that is not working this sounds like ground problem. The ground on the vehicle side that grounds the converter box may need to be moved. Try moving the ground to see if that solves the problem. If not, use a circuit tester like # PTW2993 if needed to test the pins in the connector without the trailer connected. If the right turn signal works on the 4-Way then the issue is on the trailer. If it does not work then test the green wire that goes into the...

• Troubleshooting Curt Wriing Throwing Codes on a 2017 Toyota RAV4
• The best way to start off troubleshooting the Curt T-Connector Vehicle Wiring Harness # C56350 on your 2017 Toyota RAV4 is to get in behind your tail light assemblies and remove the tee in connections so that the Curt wiring isn't a part of your RAV4 anymore. If the problem goes away then it sounds like something is wrong with the Curt wring and you'll want to get it replaced under warranty, but if the problem still exists then you'll need to take your vehicle to a shop as it would indicate...

• No power on the 4-Way Trailer Connector # 118412 on 2012 Toyota RAV4
• What I recommend is to remove everything that came with the Tow Ready wiring harness, # 118412, and then start the installation again as if it was the first time. It could be that you missed something and that by going through the steps again will reveal the issue. Included in the kit is a length of wire to run a power wire to the engine bay and connect to the positive battery post. It also makes access to the fuse for this power line easier since you can have it readily accessible in...

• Trunk Mount Bike Rack, Trailer Hitch, and Hitch Bike Rack Recommendations for a 2016 Toyota RAV4
• You do not want to put any stress or weight on that spoiler at the back of your 2016 Toyota RAV4. I definitely recommend a hitch. To carry 4 bikes, I recommend trailer hitch # e98864. Then you could use a 4-bike rack such as the Hitching Post Pro # TH934XTR or the budget-friendly Curt # C18030. A hitch mount bike rack also keeps the bikes and the rack off of the vehicle unlike a trunk mount rack. I have linked some videos of the bike racks and hitch for you. If you will be carrying any...

• Trailer Lights Always On With 2015 Toyota RAV4
• There are some vehicles that the running lights will stay on for a period of time after removing the key until after the doors are locked. It is a setting that can be changed on most vehicles. It's basically a courtesy light feature that when you unlock your doors with the remote the running lights will come on to help you see the vehicle and around it. The same happens when you remove the key and exit the vehicle to allow you to see around the vehicle. This usually will last 30 seconds...

• My 2014 Toyota RAV4 T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector
• To determine if the problem is on the 2014 Toyota RAV4 or on the trailer there are some tests you can do. First, disconnect the trailer for the RAV4. Then use a circuit tester such as # PTW2993 to test the vehicle side connector while someone sits in the vehicle and operates the light functions. If you do not get power on the connector while testing, then the issue is on the vehicle side. Make sure that the harness white ground wire is attached to a clean metal surface. No paint or coating...

• Troubleshooting Trailer Taillights Blowing After Connected to 2009 Toyota Rav4
• The problem you described should have nothing to do with the way you ran the ground wire. Having a better ground would not cause your trailer lights to blow. I strongly suspect the integrity of the wiring of your trailer. I would bet there is a short on the trailer wiring that needs to be addressed. I would inspect the wiring looking for any obvious signs of a short and fix as necessary. I attached a couple wiring FAQ's that you might find helpful as well.

• Do Hitches Ever Loosen and Fall Off of Vehicles
• As long as the install bolts of the hitch on your 2004 Toyota RAV4 were torqued down to spec when the hitch was installed you would not ever have to worry about the hitch coming loose. We have yet to hear of a hitch loosening over time and falling off of a vehicle so I can almost guarantee you would be fine.

• Replacement Anti-Rattle Lever for a Hollywood Racks SportRider SE That Never Tightens
• It sounds like the threads on the anti-rattle lever may be stripped. To fix this, all you'd have to do is replace the assembly with the Replacement Anti-Rattle Bolt and Lever for Hollywood Racks Sport Rider SE Bike Racks # HRNWLB3X. If you're still unable to get the anti-rattle to tighten, then I'd recommend contacting Hollywood Racks at that point as your rack may have some damaged internal components.

• Trailer Wiring Harness Malfunction on 2007 Toyota RAV4 and Recommended Replacement
• You are correct that the yellow wire exiting your RAV4's wiring harness should not be hot at all times. This wire should carry an output signal only when the yellow wire on the left-hand input side is carrying a signal from the RAV4's left taillight. Based on your testing results the harness is damaged and requires replacement with a unit like the Curt # C56165 or the TowReady # 118412. I suggest the Curt for its higher current output capacity. A helpful article and install video are linked...

• A-Frame Electric Trailer Jack Won't Run but the Light Works
• If the jack light is working but the motor won't that means that the jack is getting power so we can rule out the fuse/breaker being the problem. It is possible that the battery the jack is connected to has enough power to run the light but not the motor. The battery may need to be charged or replaced. A local auto parts store can test the battery. Another possible cause is a weak ground. The light doesn't need to have the best ground but the motor which draws more amperage does need a...
