Question about 2004 Toyota 4Runner
Tschometer,speddometer, odometer blinking, seat belt light is ON when it fasten and temp gauge stop working at the same time.
Your vehicle has the 4T60E transmission,and there is a speed sensor mounted on the transmission case that the vehicle's computer uses to compute vehicle speed,and relay it to the dash mounted speedometer.The best way to diagnose this problem is to first,hook up a scan tool that is available at automotive repair shops,and scan the vehicle for trouble codes first.Your vehicle probably has a stored trouble code along the lines of a Vehicle Speed Sensor (VSS).After pulling codes,go to the data stream on the scan tool and look at the VSS signal that the computer is seeing,and when the speedo acts up,and stops working,look to see if the computer is seeing,a speed signal.If the vehicle computer is seeing a speed signal,then it's probably the speedo in the dash gone bad.If the vehicle computer is not seeing a speed signal,then it is likely a problem with the speed sensor mounted on the transmission,or the wires right before it.So,to diagnose really requires a scan tool,with a data stream,or you could just have the speed sensor replaced,and hope that fixes it.The speed sensor is located on the passenger side of the transmission,only accessible from under the car,but where the pass side axle actually goes into the transmission,the sensor is directly above that point,and retained in the case with a 10 mm bolt.It has two wires going to it.Good luck.

It is definitely the speed sensor assembly which hangs outside the transmission underneath the truck. Usually runs a little over $110

Sounds like you jumped it straight to the battery post,You need to reset the computer,To do this,Unhook the battery for 3 or 4 minutes and then hook it back up.This will reset it and as long as you didn't fry a sensor or relay,It should be fine.
Please take time to rate this fixya
