I just bought a used 98 Sts with 114000 miles. Everything seems pretty good but I have a few issues. The problem is there was a lot of codes in history. List: B1327

B1327

B1327 Device Power #1 (Low Current #1) Circuit Low

B1328 Battery/Source Voltage High

B1983

B1983

B1983

B1983 Device Power 1 Circuit Low

B1652

B1652 Loss of Keep Alive Memory (KAM)

B1343 Air Inlet Door Movement Fault

B1147 Driver Side Air Bag System Malfunction

B1148 Pass. Side Air Bag System Malfunction

B2947 Security System Sensor Power CKT Low

U1064 Loss of Communications with DIM

U1128 Loss of Communications with IRC

U1129 Loss of Communications with AMP

U1255 Class 2 Initialization Error U1300 Class 2 Short to Ground

U1016 Loss of Communications with PCM

P0603 Control Module Long Term Memory Reset.

I hope I don't have a bad computer. I do not see any other dic messages or lights. Secound question is sometimes the car takes longer then normal to start. Last but not least, the previous ownwr lost the 6 cd caddy for the changer. Does anyone know who makes it or how to find a replacement? thanks in advanced.

Too many codes! Something is definitely wrong with battery/cables/connections/grounds. Check the positive cable. They are known to corrode under the red plastic cover.

I would not be overly concerned with history codes where you do not know the 'history' of the situation. My advice is to clear all of the codes and start with a fresh slate. Monitor the codes for a week or so and see if any current codes appear.

It is possible there were faults reported in the past and after the problem was addressed, the codes were not cleared.

Looking at the codes, the battery got very low -- causing most of the codes -- then they put a charger on it. I don't see any reason to believe that any of them are due to a real problem. As JimD and adillac say, clean the battery cables, which will clear all the codes except one or two that tell us the battery was disconnected, drive it for a day or two and check the codes again.

Welcome to Caddyinfo, and congratulations on your acquisition of a fine Cadillac.

Thanks guys very good tips. Ill be going on a semi long trip (about 220 miles) so ill see if the codes come back. Anyone have a suggestion for the CD Caddy or the hard starting? I think before i go ill add some injector cleaner aswell. Thanks again.

If it starts fine cold, but is hard starting hot, the FPR is a likely culprit. If it's hard starting cold, the plugs and wires are a good place to start.

You can check the FPR by seeing if there is gas in the vacuum hose. You can check the spark with a spark checker from an auto parts store. The front bank will likely show the problem if there is one there.

If you change the plugs, be sure and get the OEM AC/Delco plugs for your Northstar, and I would recommend that you look at wires, too, at 114,000 miles. If you change the wires, again go with AC/Delco OEM for your specific engine.

As far as the CD caddy, I think it may be a 12-CD changer. You can try eBay. Anyone else have any ideas on that?

I would Ebay the CD changer...

Or, I'm not sure of the particulars, but there are some Pioneer units that will plug n play with the wiring in the trunk....

In 1998, I would expect those were 12 disc cd changers in the trunk... My 1997 is a 12 disc, original Delco unit... about the only time I got thru the whole magazine was a non-stop trip to Florida....

The c.d. changer in my '98 STS is a 6 disc, and it is in the console. We thought ours was lost too, at first, but found it later, under a seat :huh:

Thanks for all the great info guys! I'll be pricing out spark plugs and wires for it. Im sure it needs it. I hope it will help my hard starting aswell. As far as the CD Caddy it is a 6 disc changer. Does anyone one know who made it? I have not been having any luck on finding a replacement so far.

Make sure you get Delco parts only for this car....TRUST ME!

You might pay a couple of bucks more, but it is worth it.

Ask anyone on here, no other wires or plugs will work right.

Update: I broke down and took it into my mechanic. Fuel pump shot. $665 (string of bad words). I will be talking to the dealership about it but legal they don't have to due anything. So at the moment im SOL.
