Starting disabled remove key

This almost sounds like a power moding issue, maybe something wrong inside the ignition switch.
The electrical part.

You say this sets no codes?

Often on a battery disconnect the radio will display "service theft system" after you reconnect it.
How is the battery voltage?

Be sure the connections on the battery are tight, if something is loose it could be losing contact and resetting the whole electrical system.

Otherwise I think I'd need more information.

Correct... there are no codes. I have used my scan tool and have also had OnStar run scan immediately after each incident. Here is another clue... If the car shuts off and you get the message "Starting Disabled - Remove Key" and you are NOT using the cruise control, you can lift up gently on the throttle pedal and the car will restart on its own. I will PM the VIN to you so you can see what else has been tried. It looks like others that have seen this are also running 2003 models.

[ewill3rd]

I got your message, please if you don't hear from me, remind me.
I am intrigued.
You have heard of this happening to others?

I have an '03 also (107K miles), and I have this exhact same issue. Started a month or two ago, but mine throws a P1629 code... It happens maybe once or twice every two weeks or so on the highway.

[ewill3rd]

How about that, this sounds pretty close to what is going on.
This looks like a KW2000 logic pulse reset.

Subject: Intermittent Stall, Surge, Stumble, or Hesitation DTC P1629


Models: 2003 Cadillac CTS with 3.2L (LA3) Engine




--------------------------------------------------------------------------------

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

Condition/Concern:
Some On rare occassions, customers may comment the engine will stall intermittently. The concern may also be described as a surge feel (not an accelerator surge), stumble, or hesitation while driving. Careful questioning of the customer, and the Diagnostic System Check, may reveal the following clues:

• The engine stalled at a steady state cruise speed with no driver inputs.


• In all reported cases, the vehicle has restarted.


• The condition is very intermittent and can take 100 miles or more to duplicate.


• The Instrument Panel Cluster (IPC) may reset and the gauges may sweep during or after the stall.


• The Driver Information Center (DIC) may display a starter interrupt message.


• DTC P1629 Theft Deterrent Fuel Enable Signal Not Received, may be stored in the Engine Control Module (ECM).


Note: The transmission can effectively push start the vehicle after the stall occurs at speeds as low as 35 mph. This would give the customer the perception the vehicle stalled and re-started on its own.

Important: This concern will NOT occur when the Tech 2 or Vehicle Data Recorder (VDR) is attached to the vehicle.

Recommendation/Instructions:
The concern may be the result of electrical noise on the Keyword 2000 Data Line (circuit 5043) that causes the ECM to reset. Install a Module Emulator Kit (Part Number 10357869). It will reduce the amount and amplitude of the noise on the circuit.

Components Provided in Kit:
Jumper (Require 1 Per Vehicle)

Terminal Part Number 12129484 (Require 2 Per Vehicle)

Tools Needed:
Crimping Tool

Wire Cutters

Wire Strippers

Soldering Iron

Pick To Remove Terminals

Black Vinyl Tape

Procedure:
•Locate ALDL Connector.
•Locate and Remove Pin 7 From ALDL Housing (Pin 7 Has CKT 5043, WH/BK, Which Is The K-Line.
•Cut Terminal Off Wire As Close To Terminal As Possible.
•Strip Small Portion Of Insulation Off Circuit 5043 and 5043A (One End Of PK Wire In Jumper assembly).
•Twist Wires Together and Double Crimp CKTS 5043 and 5043A With Terminal Part # 12129484.
•Solder Crimp.
•Locate and Remove Pin 5 from ALDL Housing (Pin 5 Has CKT 351E, BK/WH, Which Is Ground).
•Cut Terminal Off Wire As Close To Terminal As Possible.
•Strip Small Portion Of Insulation Off 351E and 5043B (Other End of PK Wire In Jumper assembly).
•Twist Wires Together And Double Crimp CKTS 351E and 5043B With Terminal Part # 12129484.
•Solder Crimp.
•Locate Best Spot To Package Jumper Assembly. (Tape Back To a Harness Bundle if Necessary /Possible Find Cubby Hole To Place it in, Whatever Works Best In Vehicle).

Will, you are a saint. May you live to be a thousand years old!

[ewill3rd]

Oh Lord no... lol. I'd get so bored. Plus I am already falling apart at my tender age.
I want to push around 80 and then head off to see my family that has gone before me.
Thanks though, that's a nice sentiment.

If any of you brave souls wants to try this fix yourself let me know, I haven't done it but I might be able to give you some tips.
This sounds like a total logic reset issue and I would not be surprised if this was the fix.
The '03 is kind of a unique car.

It is already starting. The beginning of the automotive computer age.

Your car has recovered from an unexpected shutdown. Please review the log for complete details.

I find it amazing that stuff like this doesn't happen more often actually.
You guys might not believe the level of computerization on these things and when one starts acting up... ooooh man.... look out.

YES. Please have Luke get me a package together with the necessary parts. Everything in this bulletin verifies the condition and makes sense. I especially like how the condition will not happen with the scanner/recorder attached. That was the dead end with the local dealer.

[ewill3rd]

It is best if you PM Luke directly, tell him to talk to me and I'll show him what this is about or give him the part numbers.
I don't talk to him much actually, we are both really busy and in different parts of the building.

[ssstealth]

OK, Luke sent me the kit. The part #10357869 contains both the jumper wire and the terminals needed. Since the jumper goes from the K-signal terminal to the ground terminal, it almost seems that they are trying to emulate the scan tool being attached. Since the parts in the jumper kit are sealed, it is tough to guess. I hope for $65 it is more complex than a resistor under shrink wrap.

Anyway the kit is installed and the car runs and my scan tool still reads OK from the OBD-II port. I will put it on the road tomorrow and test

[ewill3rd]

Sweet, be sure to report back with your results, I hope it won't act up again.

apparently the $65 kit fixed the problem?
