Any warning lights lit on the insturment cluster ? ABS Vehicle Speed Signal
The vehicle speed signal is generated by the rear anti-lock brake sensor and sent to the 4-wheel anti-lock brake system (4WABS) module. The 4WABS module sends the vehicle speed signal via circuit 679 (GY/BK) to all systems which require a vehicle speed signal input. Speedometer
The electronic speedometer receives a speed signal from the 4WABS module.
I would say its probably a short or a ground problem at the turn switch or a wire in that area. you need a test light and probably a multi meater and some nohow a ground or wireing problem can even drive a master teck crasy.
Your turn signals will not shut off automatically if the speedometer is not working. As for why the speedo is not working, I'm afraid I can't help you with that as I know nothing about them but I'd check the speedometer sending unit in the transmission first. It's supposed to generate a pulse for the speedometer. I work on the older bikes that the dealers will no longer work on and some Evolution powered bikes. I do not work on the digital electronics nor fuel injected bikes. I'm sorry I can't help you more.
There is a "reed switch" in the speedometer that cancels the turn signals. If the speedometer is not working, then the reed switch is probably not working either. If you'll contact me directly at [email protected] , I'll send you a trouble shooting guide for the turn signals in jpg format. Don't forget to remind me of what you need.
The speedometer sensor - VSS - vehicle speed sensor is a input to the PCM - powertrain control module -engine computer . The signal from the PCM to the instrument cluster for speed info. is sent on a serial data communication network (class 2 ) I would think it would be an instrument cluster problem . Get a used one from a auto salvage yard 15 - 20 bucks an see if it fixes it . If it does ,send your's out an have it repaired .
when the sensor was installed it was installed wrong.
They wired it into the turn signal feed.
have your dealer or, an auto electrician fix the wiring to your sensor.
Follow the turn signal's wires all the way from the hand switch to the relay to find where it is stripped and touches the chassis.Both wires are positive.Gauges and speedometer probably uses the same fuse with the turn signals so if it is blown the shouldn't work naturally.
