You need to remove the upper rad hose and the battery.
Then, use a torx to remove the 6 screws (hard to get at) which will remove the EBTCM from the brake modulator. You also must disconnect the two electrical connectors (the big one has a slide tab).
There are places you can send the module to and rebuild with warranty. I took a module from a 99' and installed it in my wife's 01'. Now the speedo, odometer, cruise and power steering work perfect and no TCM / ABS light.

Hi!!

With motor off, engine sitting for about 5 mins. check engine oil level, it is probably low, refill to level.

Don't forget to rate this post. Good Luck.

The sunroof needs to be reprogrammed after changing the battery, but it only takes about one minute to do so. The procedure is listed in the Owner's Manual.

There are very few things that you could look at to solve this problem.One take a look at the drive shaft that drives the pump for damages and excessive wear.Flush your engine to be sure your oil ports are open and be sure that the pick up and supply tubes are inserted tightly into the pump and connecting points.
