Help: Need Body Code Help

[WisconsinHick1]

B3137 - All Door Lock Circuit Low (BCM)
B1000 - ECU Malfunction

U1500 - Inter-Device Dedicated Bus Malfunction
B1004 - Keep Alive Memory (KAM)

So I have these codes coming up and my power locks do not work and power mirrors don't work but I know they are on the same set of circuits as the door locks are.

Is my BCM bad? What do the rest mean?

seemn like you have a bad bcm

seemn like you have a bad bcm

That's what I was afraid of. Does anyone know if any place has pretuned BCM's because the stealer will want a good chunk of change to program a BCM and it will have to be in the truck and trailer the truck up there.

 

[WisconsinHick1]

I know each one is different due to different options on the truck but I figure you could get the options off of the VIN number. Too bad EFIlive can't do that stuff.

you could do a remote download with a tech2 so you dont have to tow it in if you know anyone who is a GM tech. you will have to program the bcm and then do a theft relearn also.

 

[WisconsinHick1]

Well I don't know any tech's but I know a shop that might know a tech. How do you do the theft relearn?

 

[i_keyser]

you will need a tech 2 and computer with access to tis2web but you can do the 30 minute learn without anything.

10 Minute Learn Procedure
Tools Required
• Tech 2

• Techline terminal with current Service Programming System (SPS) software

1. Connect the Tech 2 to the vehicle.

2. Select “Request Information” under “Service Programming”.

3. Disconnect the Tech 2 from the vehicle and connect it to a techline terminal.

4. On the techline terminal, select “Theft Module Re-Learn” under “Service Programming”.

5. Disconnect the Tech 2 from the techline terminal and connect it to the vehicle.

6. Turn ON the ignition, with the engine OFF.

7. Select “Program ECU” under “Service Programming”.

8. Attempt to start the engine, then release the key to ON, vehicle will not start.

9. Observe the SECURITY telltale, after approximately 10 minutes the telltale will turn OFF; the vehicle is now ready to relearn the Passlock Sensor Data Code and/or password on the next ignition switch transition from OFF to CRANK.

10. Turn OFF the ignition, and wait 5 seconds.

11. Start the engine; the vehicle has now learned the password.

12. With the Tech 2 scan tool, clear any DTCs.

30 Minute Learn Procedure
1. Turn ON the ignition, with the engine OFF.

2. Attempt to start the engine, then release the key to ON; the vehicle will not start.

3. Observe the SECURITY telltale; after approximately 10 minutes the telltale will turn OFF.

4. Turn OFF the ignition, and wait 5 seconds.

5. Repeat steps 1 through 4 two more times for a total of 3 cycles/30 minutes; the vehicle is now ready to relearn the Passlock Sensor Data Code and/or passwords on the next ignition switch transition from OFF to CRANK.

Important: The vehicle learns the Passlock Sensor Data Code and/or password on the next ignition switch transition from OFF to CRANK. You must turn the ignition OFF before attempting to start the vehicle.

6. Start the engine. The vehicle has now learned the Passlock Sensor Data Code and/or password.

7. With a scan tool, clear any DTCs, if needed. History DTCs will self clear after 100 ignition cycles.

Will that flash or program the bcm cause I been having some door lock problems too.
