Battery??
Had to charge battery and seemed ok after charging. Now at times if I turn car off and then go back and start it, it's like I disconnected the battery. clock has to be reset. If I push gauges button, it takes awhile t o register air pressure in tires. Could it be a bad battery? Bad PCM (I hope not)! Any ideas??

If your battery is weak/bad,, when you fully load it (starting) the VOLTAGE output will drop very low and all the modules shutdown.
The tire pressures sensors do not send data to the BCM until the car is rolling a specific speed. There is a reed switch that is centrifically operated.
