After completing the 45 minute relearn procedure for a 2004 Pontiac Grand Prix message center Now says system not programmed


Relearn for what ? Anti theft system PK3 ? The relearn procedure is three 10 min. procedures for a total of 30 min.
30-Minute Relearn Procedure
Use this procedure after replacing the following components:
?€¢
The passkey III (PK3) keys


?€¢
The BCM


?€¢
The PCM, see important above

Important: This procedure is not available on vehicles equipped with option code (Z49).
If replacing a BCM with an GM SPO Replacement Part, perform the procedure to setup a new BCM prior to the 30-minute relearn procedure.

  1. With a master passkey III key, turn ON the ignition, with the engine OFF.
  2. Observe the STARTING DISABLED DUE TO THEFT message on the drivers information center (DIC), after approximately 10 minutes the STARTING DISABLED DUE TO THEFT message on the DIC will turn off.
  3. Turn OFF the ignition, and wait 5 seconds.
  4. Repeat steps 1-3 two more times for a total of 3 cycles or 30 minutes.
  5. Important: The vehicle learns the key transponder information and/or passwords on the ignition switch transition from OFF to CRANK. You must turn the ignition OFF before attempting to start the vehicle.
  6. With a master passkey III key, start the vehicle. The vehicle has now learned the key transponder information and the PCM has now learned the fuel continue password.
  7. With a scan tool, clear any DTCs.

How do you start the relearn procedure for the crankshaft position sensor on a 2001 Oldsmobile Aurora with a 3.5 liter v6


If there is a relearn procedure, it has to be done with a scan tool from a shop or dealership. In most cases, the crank sensor has no relearn procedure on GM/OLDs products. Instrall a new sensor and the PCM will recognize it and start the engine

Where is the body control module located in 2002 gmc envoy?


It's under your back seat. See here for picture http://www.ebay.com/itm/like/261068608953?lpid=82
Here is the relearn procedure which you have to perform so the new BCM will recognize your key and start the car:
For those vehicles that use a BCM, the BCM can learn the resistance value of the existing key by using the relearn process. In order for the vehicle to start, the BCM (as well as the Passkey module in other vehicles) must identify the resistor pellet in the key, then the BCM sends a password to the PCM. If this password matches the password stored in the PCM, the system enables fuel delivery. So you can see that if either the BCM or PCM are replaced, a relearn procedure is necessary. This same relearn procedure can be used if an ignition key with a different resistance value is used to replace the existing key. Before beginning the relearn, make sure there is a fully charged battery in the vehicle, and both the BCM and PCM are properly powered up and in communication with each other. Now you're ready to initiate the relearn procedure.

1. First, insert the ignition key and turn the ignition switchto the "On" position (Do not start the engine). Leave the switch on for 11 minutes. The security light may flash or be on steady during this 11 minute period. Make sure the light is no longer on or flashing before proceeding to #2 .
2. Turn the ignition switchoff for 30 seconds.
3. Turn the ignition switchto the "On" position (as in step #1) for 11 minutes again.
4. Turn the ignition switchoff for another 30 seconds.
5. Turn the ignition switchto the "On" position for 11 minutes a third time.
6. Turn the ignition switchoff for 30 seconds one final time.
7. Turn the ignition switchto the "On" position one final time and wait 30 seconds.
8. Attempt to start the engine. If the engine starts and runs normally, the relearn is complete. If the engine does not start, check for trouble codes and address them before attempting the relearn procedure again.
You can pick one oif these up for $20 or less at a junkyard. For those vehicles that use a BCM, the BCM can learn the resistance value of the existing key by using the relearn process.

Pcm relearn


relearn
what large topic. and wow, not even a FUNCTION STATED
just the WHOLE PCM,.
no symptoms, no issues, just that.
not sure what engine you have there, and matters !!!
most PCM's relearn EVERYTHING after you pull the battery
connections or the PCM memory fuse. IOD fuse.

dont pull the battery, or lose radio passcodes. (bricks IT or NAV bricked, if opted)
lots of learn, paths.
fuel trim? ( does o automatically as does spark)
spark advance, and knock data?
transmissions all have learn mode, and do so automatically when reset.
now the last one, some cars, the TB (throttle ) body must be relearned, some are auto learn others not.
aka: throttle by wire ,relearn.
did you replace something (my other shoe drops......)

did you first scan the PCM and see if there are issues.
if not, why not, why work blind>?

there are other learns
seat position (guessing BCM)_
pedal position relearn, omg.
Sentry Key "Customer Learn" Mode
transmission quick learn or drive learn (read the FSM yet?)
chapter 8e-290 + all those learn steps for trans, takes no tools.
RTM? yet?

more?
instrument cluster learn mode? Odometer?
this?
At the garage door opener receiver (motor-head unit) in the garage, locate the 9learn9 or 9smart9 button.
sun roof relearn?

TPS learn(excepted)
"Is the voltage reading within the listed specification when the
jumper wire is installed?
Yes >> Replace the Throttle Body Assembly. Disconnect the Battery
when replacing the Throttle Body Assembly. After
installation is complete, use a scan tool and select the
ETC RELEARN function.

Perform the POWERTRAIN VERIFICATION TEST. (Refer
to 9 - ENGINE - STANDARD PROCEDURE)
No >> Go To 4
NOTE: Remove the jumper wire before continuing."

ill stop here, (i scanned the whole FSM for you on LEARN)
these newer cars the PCm .,BCM and other modules work on cooperative modes. Ill be the last to ever say , where learn data i stored, that i below my paygrade (retired and zero) LOL !

why not post something more focused.
like
I'm considering a new TB.
what do I need to know.?
or??????????????????

I have a p1336 code. is it a bad sensor or a wire problem ?


This is from updated GM service manual of mine.


According to the GM factory service manual, the OBD-II trouble code, P1336, is defined as follows: DTC P1336 CKP System Variation Not Learned. The factory service manual does not enumerate all of the symptoms of this trouble code, but after consulting a professional custom PCM tuner, it was learned that aside from the annoying light on the instrument cluster, the other symptoms exhibited may include: poor vehicle performance, and loss of misfire detection diagnostics.


This DTC is particularly nasty, because simply clearing it by disconnecting the battery, or clearing it using an OBD-II scan tool will not address the problem. The code will be set again later unless the vehicle is run through the actual "crank relearn" procedure.


Fixing the Dreaded P1336 DTC


There is only one way to properly fix the P1336 DTC, and that's to perform a "crank relearn" procedure, or as the GM factory service manual procedure calls it, the CKP System Variation Learn Procedure. This procedure can be initiated and performed by GM's be-all end-all scan tool, the Tech-2. It can also be performed by some aftermarket scan tools. Furthermore, some of the PCM tuning software applications are capable of initiating a "crank relearn" procedure.

How does replacing the battery effect the pcm


The PCM can't function without the battery.
Once replaced the PCM has to relearn the operating functions of the vehicle.(usually within a few drive cycles)

For most enthusiasts that encounter this issue, the best course of action is to bring the vehicle to a local GM dealership and have them perform the procedure. Unfortunately most dealerships will charge a modest fee for doing this (upwards of USD $100 in some cases).
