abs and brake light on
 

hi my abs and brake light are both on and came on at the same time. after doing some research i found that it could be a fuse so i checked and none were burnt out. brought it to a shop and they gave me abs codes 37,36,26,and 35 if anyone could help that would be great

Does your speedometer seem like it is slow to pick up? Or delayed? Like stay at 0 and then just shoot up to speed?

Speedometer works fine. I was told that you can use a voltmeter to check the sensors. Does anyone know how many these trucks have

had the same sort of issue with my clockspring behind the steering wheel only difference was my air bag light was also on and still is

Rear diff sensor. Either the sensor or the small wiring harness that goes to it.
