i just changed out the battery terminals because they were kinda corroded, i had to take off the starter to do so. Well, now i am done, and the car is triggering the "ABS INOP", "Low traction", and "ASR OFF" lights. What could have happened?

Poor connection or low voltage come to mind. Check your work and the ground wires on the RH shock tower.

i checked all connections... everything is firm. The +cable splits into 3, and goes to the PCM, alternator, and the starter. I checked and i am getting power at the end of all three.

The car starts fine and everthing runs ok except these lights come on and the LED on the ASR switch does not come on. Is there a sensor/switch for the ABS and/or ASR near the starter that could have come loose???

if its anything like mine is than it has a lead right off the battery that goes to the ABS on the other side of the truck. Look on your ABS unit and plug the connector with a large red wire and test it for power there as well as the black for ground

Damn, I had this same thing happen to me a couple yrs back, & I cant remember what I did to fix it
I remember it was an easy fix, try disconnecting the battery for at least 10 min before hooking it back up. That's what comming to mind.

I would check power at the pcm, not if its there, but if it is less than 12v. If its anything less than 12v, the pcm goes intermitten and lights start coming on,

i also installed a brand new battery so there should be 12v to the pcm, but i will grab a voltmeter and check anyways.

its weird though because when i pull the hand brake up the "low traction" light pops up. Then when i am lowering it, all the lights go off. When its all the way down "ABS" and "ASR" both come on again..... Strange huh?

Any other suggestions?

thx
