Cadillac Repair: 1997 Cadillac DeVille, cadillac deville, seat air

Question
"I have a 1997 Cadillac DeVille that will idle all day, but when I
start driving the tempature starts to climb. I can get it up to around 60
mph and the temp goes down, then when I get into slow traffic it starts
climbing again, but if I park it and let it idle it will cool down. I
have had the water pump replaced, had the radiator flushed. I have no
oil in the water, or smoke from the exaust. I'm at a loss as what to
check next, or if this is something that can be fixed. The thermostat has also been replaced.

The following codes appear:
PCMPO 325
PCMPO 603
SDMB 1147
SDMB 1148
RFAB 2560
PCM?

I thank you in advance for your time, and help.

Answer
PCMPO 325 = faulty knock sensor.
PCMPO 603 = Battery was disconnected at some time.
SDMB 1147 = drivers seat air bag problem.
SDMB 1148 = passengers seat air bag problem.
RFAB 2560 = unknown.
PCM?


Since some of the codes involve AIR BAGS, I STRONGLY suggest that you have your dealer look at it.
