20 Most Recent 2004 Cadillac CTS Questions & Answers


I will quess that there is a 90% chance, you will have to
pull the transaxle & have it rebuilt

From here forward, you change your trans fluids every three
years ,along with the power steering.That will fail next.

2005 CTS 3.6 Dead battery, key stuck, service anti theft and nothing happens when you turn key, Ttried everything, ECM reset, key memory reset, charged battery to 12.7 volts, locked door w remote and opened w key, anyway you get the idea. After 3 days of online reading and trying, THIS IS WHAT WORKED, 1. put key into on position 2. removed sarter relay from front fuse panel 3. jumped 1st pin closest to fender and passenger seat with pin that is closest to motor and front fender. I used a paper clip and just made contact long enough for car to start. ran car for five minutes and took key out and everything went back to normal. then I took car to advance auto parts to have engine light reset. if car does not go back to normal you have ECM (car computer) failure. video on YouTube under "no crank, no start"

Had the same problem. 2005 Cadillac CTS with the 3.6L V6 would not start after a oil change. I started looking for wires and stuff that might have been disconnected. That is when I realized that I had also checked the air filter. The hose from the air filter box to the intake had come slightly loose from the intake. The car would not run with an air leak at the air cleaner box box hose. Put the hose on tight and problem fixed.

These are not trouble codes. They are addresses of multiple ECU control modules that the scanner found. You can navigate each one, subject to what it reports. Any actual trouble codes would be stored within each module separately if there are any.

The traction control light in these years is usually a bad wheel speed sensor built into the wheel bearing. Cost around $600. The audio may be as simple as entering the unlock code. The deceleration could be a hundred different things so you'll have to pay to get that diagnosed.

STARTING DISABLED REMOVE KEY
Refer to Theft Systems Description and Operation in Theft Deterrent

STARTING DISABLED REMOVE KEY
The radio illuminates the STARTING DISABLED REMOVE KEY message when the VTD system has disabled the starting system. The radio receives a message from the theft deterrent control module via the serial data circuit requesting illumination.

Your best bet ,take it to Cadillac dealer and have it checked . Could have DTC'S - diagnostic trouble codes
DTC B1015
DTC B1016
DTC B3031
DTC B3055
DTC B3060
DTC B3090
DTC B3935
DTC B3976
DTC P1629
DTC P1630
DTC P1631

The theft deterrent module or the insturment cluster or the ECM is not seeing correct info.
The vehicle theft deterrent (VTD) system functions are provided by the theft deterrent control module. When an ignition key is inserted into the ignition lock cylinder and the ignition is switched ON, the transponder embedded in the head of the key is energized by the exciter coils surrounding the ignition lock cylinder. The energized transponder transmits a signal that contains its unique value, which is received by the theft deterrent control module. The theft deterrent control module then compares this value to a value stored in memory, learned key code. If the value is correct the theft deterrent control module sends a random generated number to the transponder, this is called a challenge. Both the transponder and the theft deterrent control module perform a calculation on the challenge, if the calculations match the theft deterrent control module sends the fuel continue password via the serial data circuit to the Engine control module (ECM). If either the transponders unique value or the calculation to the challenge is incorrect the theft deterrent control module will send the fuel disable password to the ECM via the serial data circuit. The components of the VTD system are as follows:
• Theft deterrent control module
• Engine control module (ECM)
• Ignition key (Transponder)
• Ignition lock cylinder
• Security indicator

Hey Gary, take your car and get the transmission fluid and filter changed immediately... you will be glad you did...(expensive lessons speaking!!!)

If you remove the sensor from the exhaust pipe, measure the element if it a heated sensor. It should give a reading of 3 - 6 Ohms. Measure the voltage from the sensor wires and when heated with a blow lamp the reading should increase with heat. If it does, it is probably OK.

If you pull the windows they will separate from the window channel hardware. If separated there is nothing to keep the window glass held up and it will fall back down. Check your fuses for power windows, there may be more than one. Also check the power window relay(s). The relays may be located under the hood in the fuse box.

Your dts uses drive by wire. The gas pedal is actually an electrical switch connected to the engine computer which then actuate a throttle body motor which causes the car to speed up or slow down. If you mean the car won't acceleration then the throttle actuator is probably going out, this is common and you replace the throttle body assembly as the actuator is sealed onto it. Had the same problem with my 04 srx (which is mechanically the same as a cts). If you have a check engine light on (and you should) get the codes read first as there are a few other problems that can cause throttle problems, however they are less likely the cause.
