2005 Cadillac STS Questions & Answers
How can I reset security?
Hello. It seems your key fob has a low battery. This will cause it to, partially, malfunction; making the car 'think' it is about to be stolen. Attain a new battery for your key fob. Good luck and keep me informed; if you want to.
What is causing battery drain?
when you have no clue then you go see an auto electrician it take special equipment to test for current draw which I can not afford
2005 sts caddy when abs traction Control System and stability system lights flash. Loses power until shut off ignition and turn back on. No lights on now but had scanned and got codes co242 and co561
Do you know what diagnostic flow charts are ? Every DTC has a factory diagnostic test's to test electrical circuit's , computer , sensor's etc...
DTC C0561 System Disabled Information Stored
The electronic brake control module (EBCM) disables the traction control when other electronic control modules set DTCs for components that effect the operation of the traction control system.
The PCM or BCM diagnoses a condition preventing the engine control portion of the traction control function and sends a serial data message to the EBCM indicating that torque reduction is not allowed. The PCM or BCM will typically set a DTC and the EBCM will set this DTC.
Diagnostic Aids
This DTC is for information only. As an aid to the technician, this DTC indicates that there are no problems in the ABS/TCS system.
.
DTC C0242 PCM Indicated TCS Malfunction
The electronic brake control module (EBCM) and the powertrain control module (PCM) simultaneously control the traction control. The EBCM sends a serial data message to the PCM requesting torque reduction. When certain PCM DTCs are set, the PCM will not be able to perform the torque reduction for traction control. A serial data message is sent to the EBCM indicating that traction control is not allowed.

Inspect the external RF antenna connection at the RCDLR. First, gently pull on the coax connector at the module. If the coax comes out, then it wasn't seated properly. Remove and carefully inspect the coax connection for bent blades or a bent center pin. Fix coax connection if necessary and re-seat connector until a "click" is heard. Gently pull on the coax connection to make sure it is seated properly. Was the inspection made?
Press each button of the transmitter one at a time.

My 2005 STS wont eject the nav CD and when I try to use th navigation it says
These navigation disks are prone to contamination from dust particles over the years. If the disk is not damaged (scratched), you can try gently cleaning it to see if that works. You can also try a special lens cleaning disc to clear any dust from the reader.
However, if you have you followed all the owners manual instructions for removing it and it won't, you have a much more serious problem with the system. All I can suggest is a trip to a dealer to see if they can help.
I have a shuterring problem with my cadillac
Have it checked with a code reader. You have a dead cylinder. The code reader will tell you which cylinder it id. That cylinder needs a fuel injector change. Symptom being, when start moving and normal throttle, shifts thru the gears fine with no loss of power. As soon as it goes into Overdrive, it feels like the whole car is going to vibrate off its chassis. That thumping is what we call a dead cylinder. Because it is just that, dead. Yet when you push the pedal down, it will downshift and run fine. Change the injector.

Take it an have vehicle scan done . Your vehicle has a vast amount of electronics , control modules , communication networks for the modules to share data on . All it takes is one of the wires touching ground to cause all kind of problems . There are modules inside the doors that control power windows , locks , mirrors etc. . Hooking up a scan tool that can check for communications from all modules . Not a code reader . A GM factory Tech 2 would be best . I work for Cadillac ,have for twenty years .
2005 STS LED TAILLIGHT, HAS TWO ROWS OF LEDS, ONLY ONE ROW OF LEDS ARE LIGHTING UP?
Hello John Bland,
Light Emitting DIODES. DIODES... all semiconductors
are highly susceptible to FAILURE if improperly handled.
In a protected (anti-static) environment they do have an EXPECTED LIFE CYCLE.
In an UNPROTECTED... POORLY handled environ... you
can expect the slightest SPARK... (you might not even feel)
to render any/all semiconductors into USELESS trash.
STUDY UP:
ESD = ELECTRO-Static Discharge.
Modern electronics should only be handled by qualified
technicians...
REAL "qualified" technicians (at least while the BOSS
is
watching) wear anti-static wrist-bands.
$300 Compared to $10K, $20K and $60K (etc. etc.)
circuit boards
YOUR STS tail lights are pretty cheap...
I'd still recommend borrowing, begging or buying
a WRIST STRAP ...
I am just saying.
(see below (50 years industrial experience)).

Having problems with climate control. Temp setting does not come back on to the last setting it always comes back on at 75. Also when pushing the front defrost it doesn't blow air.
You may want to have it check for DTC'S diagnostic trouble codes . A code may point to the problem , these HVAC systems are very complex .
DTC B0248, B0268, B0408, B0418, B0428, or B3531
The HVAC door actuator is an electronic motor with a feedback potentiometer. The HVAC control module supplies power and ground to the actuator. The HVAC control module controls the direction of the actuator by changing the polarity of the control circuit. When the actuator reaches the desired position, voltage is removed from the control circuit. The HVAC control module determines the current position of the actuator by monitoring the feedback voltage of the door position signal circuit. The feedback potentiometer position is a function of the actuator position.

Do you know what a scan tool is ?
Install a scan tool.
Turn ON the ignition, with the engine OFF.
With a scan tool, command the appropriate actuator in both directions.
Does the actual parameter of the appropriate actuator change?
