2010 Cadillac DTS - Page 9 - Answered Questions & Fixed issues

cars sold new have 3 to 10 audio options. and are not the same wired. ever.! even engine options change fuse boxes. oops not told the service manual covers all that, why not buy it? or test all fuses in all boxes 5 boxes. cab/ and engine bay ? (look ma' no books me)??? or open glove box see users guide and is matched to your not told VIN and shows all fuses.! the users guide is free from Cadillac. get it? if lost? i,m teaching how to fish. here. next I delve into some brief specifics. no VIN told and not radio option package told this car has RPO data, , the RPO sticker shows (RPO is GMs name for "as built" options "THIS CAR" only. all codes for RADIO and now you know what is in any GM car made,.(GM will i fact decode your VIN and send you the RPO list. for free) the radio list is, day1, DTS

1. (US8) AM/FM Stereo, CD, MP3, RDS, EQ
2. (US9) AM/FM Stereo, 6-Disc CD, MP3, RDS, EQ
3. (UQ3) 8 Channel Amplifier (as fuse rear 20a )
4. (UQA) Bose 6 Channel Amplifier(rear fuse too 30a)
5. (U2K) Digital Radio

now the magic of networks here. "The main radio power is supplied by a 15A fuse located in the RBEC. The radio does not require a discrete ignition feed circuit for power moding. The power moding is accomplished using a structure of Virtual Networks (VN). The Power Mode Master (PMM) transmits the GMLAN power mode signals." so not scanning the car OBD2 port you miss out on key network and other errors (DTC) I will now decode that for you, it means scan the cars OBD2 port see why the radio is failing. UBEC means under hood RBEC means. rear compartment fuse block ok here is free cute video see fuses named audio. under set if havea powerful PA amp option there are more fuses. radio, and amp , audio. look or buy the SM. https://www.youtube.com/watch?v=hwOxLbkFG90 end.

Do you have any trouble codes? check for vacuum leaks!

have vehicle scanned the trouble code will assist in solving problem

I have a 97 sts and that bulb runs through the accessory fuse located under the dash on the drivers side.

You will need to refer to the Cadillac service manual for the exact sequence and specs. Generally, the torque specifications for the bolts range from 8-11 ft-lbs and should be tightened in the following order: (1) center bolts, (2) outer bolts, (3) inner bolts, (4) lower bolts.

My guess is Body Control Module comm failure, which would explain inoperative windows and door locks. Lighting is likely non operational also?

Check any/all fuses labeled BCM. You could also try disconnecting battery for few minutes and see if problem clears.

fit the TCM and use a scan tool to reset the unit

You can't. Fix the problem not find a way around it. Have a read https://www.fixya.com/cars/r29887709-gm_passlock_security_system ..

I think on this model it is a pain in the tailbone to remove it. At the pedal end the connector is held in with 2 tiny pegs that you will need to carefully press out of the way with two small, flat bladed screwdrivers.This is one of those jobs that will either release first time or take all day and the skin off your knuckles. It will also involve a lot of cursing and swearing at the vehicle.

Which engine is fitted to your Cadillac? As a general rule Cylinder One is usually positioned nearest the belts and pulleys on the end of the engine, the furthest away from the transmission. Stand in front of the engine with the belts and pulleys nearest to you. The cylinders to the LEFT are the Odd numbers, (1,3,5,7), and the cylinders to the RIGHT are the Even numbers, (2,4,6,8). Number One is LEFT side nearest to you.

Fuel can go bad after sitting for a long time...fuel pumps sometime will also get rusted with the bad fuel...try using starter fluid and see what it does.

it appears that 4 are sold as package and suggests that placement does not matter.

Most likely the gaskets need to be replaced... maybe the valve cover, oil pan, etc...if oil gets on the exhaust it can cause the oil to smell

That depends on whether you have Passkey I or Passkey II See this post for instructions https://ricksfreeautorepairadvice.com/passkey-versus-passlock/

To replace the freeze valve in a 1998 Cadillac DeVille, you will need to follow these steps:

1. Locate the freeze valve. It is typically located near the radiator or the heater core, and it is responsible for preventing the cooling system from freezing in cold weather.
2. Disconnect the negative battery cable. This will prevent any electrical accidents while you are working on the car.
3. Drain the cooling system. This will allow you to remove the freeze valve without spilling coolant all over the engine compartment. To drain the cooling system, locate the drain valve at the bottom of the radiator and open it.
4. Remove the freeze valve from the cooling system. This will typically involve loosening the mounting bolts or screws that hold it in place, and then pulling it out of the system.
5. Install the new freeze valve. To do this, you will need to reverse the steps you took to remove the old valve. Start by placing the new valve in the same position as the old one, and then secure it in place with the mounting bolts or screws.
6. Refill the cooling system. Once the new freeze valve is installed, you will need to refill the cooling system with the appropriate type and amount of coolant.
7. Reconnect the negative battery cable and start the engine. This will allow you to test the new freeze valve and make sure it is functioning properly.

It is important to follow these steps carefully to ensure that you replace the freeze valve correctly and safely. If you are not comfortable with performing this task yourself, it is recommended that you seek the assistance of a qualified mechanic.
