For many reasons unknown to man some have posted that their directional have started to blink faster than normal.
One reason for this is if you tow a trailer and unhook the lighting plug, it may be necessary to perform the routine listed below. If you have LED lights, this may also be the cause and you may have to install a load equalizer.
Try turning on the ignition and press the left directional switch and let it blink over 5 times and do the same for the right side. The TSSM/TSM sometimes will adjust to a varying load. Also make sure when it starts blinking faster that the bulbs are still both blinking front and rear, you may have a swinging element in a bulb which the TSSM/TSM interprets as a bad bulb.
You will sometimes set DTC code when this happens which gives you a light on the dash after start up.
You'll find the procedure for checking the codes here...
