going to tackle the abs/brake lite issue today on the '00


Recommended Posts

after reading many posts on this issue.. This is a pretty common problem.Ours comes on after it self-diagnoses (after engine start) and before vehicle moves...I'm confused though on this, if the sensors are at fault or inbalanced, wouldn't it cause the warning light to come on AFTER the vehicle moves?? Will do the fuse check and visual inspection of connections here this morning...

I had this on my Cirus, repeatedly. After several trips to the shop, they finally replaced the wheel sensor. It's stayed fixed for several years since. The trick is to figure out which one. It would have been cheaper to replace it the first time.

Simple test... Drive the truck and watch the speedometer. Does the speedometer function correctly without jumping up or down or falling off to 0 suddenly? If YES...

Then its a front sensor problem and I highly suggest you replace both as a unit.

If NO...

Then its a rear speed sensor.

Once corrected the light will automatically reset after driving the truck a shot distance.

On mine the brake and abs light are on,driving the speedo stays good. It is my understanding that the red brake light will come on also after an abs fault. At least that's how the FSM states it.
