Are you trying to move the car with it in gear when the engine stalls??

Is the car in neutral (park if it's an automatic) and you are trying to raise the RPM's??


You should pull and post all your codes.

If you have never done this here is how:

OR



http://www.c5forum.com/ayc/dtcdic.php







List ALL your codes and the H or C or HC that follows each 5 character code.

List the codes under the sensor they show under. ie 10 - PCM or 28 - TCS or 40 - BCM......... etc

40 - BCM
B2587
B2588
B2592
B2593

Your stalling symptoms sound very much like the Column Lock 2mph fuel shutoff. The LDCM and RDCM codes are indicative of a recent battery related event. Have you had the battery recently disconnected/reconnected?? I suggest that you pull the battery and have it load tested. If it is low it will cause column lock related issues such as the 2mph fuel shutoff.

If you have a digital multi meter, measure the voltage across the battery posts. If the voltage is 12.5 or less then I would highly suspect the column lock 2mph fuel shutoff. A good battery at full charge measured across the battery posts with the key OFF should measure 12.7 to 12.9 volts or more. Don't bother reading the voltage off the dash gauges as they measure the output voltage of the alternator with the engine running. Hence they monitor the state of health of the charging system and NOT the state of health of the battery.

With the possible exception of the TCS C1255 code, all the others are MOST likely the result of your disconnecting and reconnecting the battery. The battery cable makes and breaks electrical connectivity with the battery post and this powering up and powering down of the sensors rapidly cause them to generate bogus codes. Some codes are known to disappear when the ignition is changed from on to off. To try and gather some additional information from the computers please read on.

Please try this:

1) disconnect the battery for at least 1 hour.

2) reconnect the battery

3) pull the codes and then clear ALL of them. See the video above for how to clear the codes. Doesn't matter what these codes are so don't bother writing them down

4) start the engine and let it idle.

5) pull the codes with the engine running. To pull codes with the engine running you MUST use the reset button to clear all messaged in the DIC. Then pull codes as normal.

6) save those codes to post back here in this thread.

7) try to drive the car. If it stalls please pull the codes again.

Post the codes that you have collected in this thread.
