Installing load resistors will mimic the filament light bulbs load on the system. If it lights up, you know the relay is good. Once you have successfully replaced the relay, your turn signals should operate as desired. They are designed to be compatible with a vehicle’s CAN bus system and prevent bulb failure warnings and error messages (sometimes produced by standard LEDs, because of the change in load on the vehicle’s electrical system). If I signal left, the blink is double-time and the front signal appears 'out of sync'. When a lamp blows, there is less load on the electrical circuit. Thankfully, your vehicle’s owner’s manual should give you the exact location of the junction box. Which means LEDs present a much higher resistance. Step 1 - Turn the key to the "ON" position, and push the turn signal switch in the direction the system blinks fast in, right or left. Ok I'll try that. There's no less installed and checked the bulbs and all are fine. The next reasonable possibility is that there is a short somewhere in the wiring. Almost all vehicles have their own specific flasher relay. Using your vehicle’s manual or online guide, locate the relay cluster. In some models, it is next to the steering wheel column. As well as a blown light bulb causing the turn signals to flash faster, older vehicles were fitted with a turn signal relay (indicator relay or flasher unit). If the turn signals are controlled by electronics within one of the vehicles control modules, the only way of adding the LED turn signal relay is to bypass the control module. Even though the replaced relay is for the same make, it may be for a different version, like a hatchback. These relays (or flasher units) can fail and will have similar symptoms to a blown light bulb. This relay is designed for your vehicle’s turn signal configuration. To modify the vehicle to use LED’s (for turn signals), you have two main choices: There are advantages and disadvantages to both: You will only need one LED compatible turn signal relay for all the lights. By following these 5 tips, you can soon be back to driving safely. Another reason why turn signals flash fast is if the car isn't supplied with enough voltage. This can cause your blinkers to flash faster than normal. Fortunately, you can remedy this by hunting down the correct flasher relay. If you don’t have one or the other, you can pick these up at your local auto parts or big-box store. Check the replacement light bulb is the correct wattage, or the light will be too dim or too bright. If all of your bulbs are working, but the indicators are still flashing too fast, this may suggest either faulty wiring – a poor ground connection for that lamp assembly. don't worry, they are supposed to flash! The legal flash rate for indicators is between 60 to 120 flashes per minute. How to Make LED Turn Signals Flash Correctly: How to Install Load Resistors for LED Turn Signal Lights: Install an LED Compatible Turn Signal Relay: Increase the load on the electrical circuit by introducing load resistors: How to Repair Vehicle Lights Acting Strangely, Trailer & Bike Rack – Type of Electrical Connectors, Next - Towbar, Trailer & Bike Rack Electrics, Only replace turn signal (indicator) light bulbs with the same type (see the section on. Continue reading to find out how to fix a fast blinking LED turn signal. In others, it’s located somewhere near the vehicle’s battery in the engine compartment. Once you have accessed the relay, start up your vehicle. SPONSORED LINKS. If I hit the hazard switch, all 4 markers flash in sync and at the right speed. For a safer, long-term fix, replace the bad wiring altogether. It’s likely that a broken lamp will have caused the indicators to flash faster (hyper flashing). The smaller load causes the electronics (or turn signal relay) to switch on and off faster, thereby causing the turn signals to flash faster. Step 2 - Inspect both the front and rear of the vehicle to identify the directional signal bulb failure. Please note that the information contained within these pages is for guidance only and could contain inaccuracies. The indicators flash very fast ,and the back ones do not work at all.the bulbs are all ok , i was told it could be an earth problem.but i dont no where to start. There are ways around this, but it involves fitting additional components. Alternatively, rust or corrosion could be to blame. Favorite Answer. But my bulbs all seem to work. Turn Signal Relay (3 pin) Indicator Relay (2 pin) These relays (or flasher units) can fail and will have similar symptoms to a blown light bulb. To upgrade turn signals to use LED’s, you will need to take account of the different load LED’s have on the electrical circuit, (compared to filament light bulbs). These relays were often controlled by a bimetallic strip, which would rapidly heat up and cool down (and are not as reliable as modern electronics). RussK. Or, they just fail completely! This happens when the exposed wiring comes in contact with your vehicle. Bulbs flash too fast if they are drawing more current than they should. Next, place the test wires across both power/control terminals. You get in your car to head to work, and as you use your turn signal, you notice it’s blinking fast! Though the hazard lamp function is working fine;blinking fine at normal tension (speed), but both left and right indicator lights are blinking way too fast. Patching it up with electrical tape should serve you well in the short-term. Ok, so I failed inspection today for my passenger side blinker, it's blinking too fast. I cannot find mention of a relay or a fuse for the indicators … https://carfromjapan.com/article/car-maintenance/fix-turn-signals-blinking-fast Replacing the relay is equally straightforward. I noticed sometimes the turn signals worked if I revved the engine a all the way up to the rev limiter. Product Details. Bad Combination Switch. In newer cars, the turn signals are controlled by electronics (usually one of the many circuits buried inside one of the vehicles control units). front, front-left & rear) indicator bulbs had gone kaput.
