Keyless Entry System Description and Operation - Active The keyless entry system is a vehicle entry device. The keyless entry system is used in conjunction with the door locks to unlock the vehicle. Keyless entry will lock/unlock a door or open the rear compartment lid when a corresponding button on the keyless entry transmitter is pressed. This is accomplished by the transmitter sending a radio frequency to the remote control door lock receiver (RCDLR). The RCDLR interprets the signal and activates the requested function via a serial data message. A low transmitter battery or radio frequency (RF) interference from aftermarket devices, such as 2-way radios, power inverters, computers, etc., may cause a system malfunction. High RF traffic areas, such as gas stations that use pay-at-the-pump RF transponders, may also cause interference that could lead to a malfunction. Keyless entry allows you to operate the following features: • Door lock/unlock • Rear compartment lid release • Illuminated entry lamps • Panic alarm/Vehicle locator • Remote vehicle start Your best bet , take it to a qualified repair shop .

I have a 08 cts all my service stabiltrak all wheel drive off and traction control off. I changed the battery and alternator as well as plugs and pulleys. Codes were off for short time driving like 3 mins and all back on. Anyone have idea were I go now?

fill air in the wheels and take around travel for 10 min

under seat release it

Will it allow you to select the track you want before having to select the Yes / No option ? If so select the track you want and then hit No. Or try double clicking on the single track to see if that works. Good Luck.

You have a problem in the engine or transmission that is serious and to avoid further damaging of the components the powertrain computer has limited available power. You must now have the computer system scanned for fault codes, then based on the fault codes you perform diagnostics and repair the problems.

I would have to hear the noise to even begin to guess what it is. Have a local tire shop drive it, they seldom charge for this type of advice hoping to get the repair job.

Cadillac's are second worse to Mercedes. To many computers on them. Most computers ground what you want to operate. Could be the rear BCM or wiring. Have the codes read. takes a scanner.

If it works with out the bearing sensor being plugged Leave it. You may get ABS codes/light, but you still have brakes. Just not anti lock. The steering module is bad. You have already proved it, You unplug it, It works. Plug it in, it is bad. It is shorted out in side the computer. I just did a diesel engine, Called the computer after 30 minutes. Owner of the diesel said it wasn't. Reached up and pushed a solenoid for fuel shut off. I told them all, it just proved my point, The computer is supposed to do this. They replaced the solenoid, still no start.

When you changed the BCM you basically disabled the car, the Key will have to be reprogrammed to the cars immobilizer, that is if the immobilizer is still good, If the BCM shorted (Burnt) out, it could have affected other components in the car. I would let the dealer run a diagnostic on the car. They may be able to reflash the ECM / BCM and immobilizer or they may have to replace them.

Could be your temp sensor needs replacement or your wiring has been damaged. You should get a OBD II computer tester that plugs in under the drivers dashboard. Never plug in or unplug with the key in the ignition. After the tester has booted then turn your key. You could have multiple error codes and guessing is really a long way and very expensive. Best get some solid clues to follow and good proceedures as you can cause more problems messing with things. buy a Haynes repair book if it goes into computer codes. If not buy Chiltons or better yet a manufacturers repair manual for that model. Try the public library as they may have all the books you need.

Lube the locks and check your settings in the control panel to make sure they did not get changed to not allow the remotes to work

Thermostat might be sticking. Try replacing that

Fuel pressure. Running out of fuel. EVAP canister purge valve. Evaporative emission system. Low compression, cylinder No.3. (check valve clearance and throttle plate for excessive wear) Engine control module (ECM).

I had a similar problem with my driver's door on my 2009 CTS. It would work sometimes, then finally not at all. The key fob wouldn't work, nor the electric switch inside. It could only work manually or with the key. Mine ended up being the lock/latch actuator inside the door. I got one on e-bay and replaced it myself. $150? Probably a $300+ job at the dealer. There were a bunch of them on ebay. This is a clue that there is a real problem with these. It'll look something like this:
