We drove to round rock from midlothian tx car ran fine started every where .pulled up to son s house went to start and battery went dead .pushed off went to oriely checked alternator charging fine .changed battery started good then noticed water temp went to 260 but heads up shows normal disconnected ground on battery a few min and still pegged 260 . Some on an other forum said something about pulling PCM fuse and disconnect battery to reset . Do I install fuse back first or battery ground on then fuse?

Try resetting or looking for codes first. What does the DIC say?
by: Chris

Do this first.

1. Turn your key to the "ON" position, but do not start the engine.
2. Clear any present messages by pressing the RESET button.
3. Hold the OPTIONS button down, and press the FUEL button 4 times. (This will get you into the "codes" section of the DIC.
4. The computer will automatically display all the codes your car has created. It will cycle through each code every 3 seconds. (Have a pen and paper handy to write down the codes)

Note: Any code that ends in an "H" is a history code (something that has occurred in the past, but is not reporting as an error currently.)

5. Once the computer has finished going through all of its codes, press RESET to enter Manual Configuration mode. It should start with a module and show "NO CODES" or "# Codes."
6. To optionally reset codes once in manual mode, press and hold RESET until is displays "NO CODES."
7. Press OPTIONS to go into the next module (ie, from PCM, or Powertrain Control Module, to TCS, or Traction Control System.)
8. Repeat Step 6 until you have reset all the codes in all the computer modules.

It doesn't really matter if you pull the fuse or not just extra work. Just disconnect the battery.
