LLY: 911: new bcm and now it will not start
- Thread starter dirty_max
- Start date
its security issues. Thats why it wont start. You can do a manual relearn and get the truck running.
Try this
1. Insert ignition key and turn to the “ON” position. Do not attempt to start the engine. Leave
the key in the “ON” position for approximately 11 minutes. The security light will be steady
on or flashing for the 11-minute period. Do not proceed to Step 2 until the security light
turns off or stops flashing.
2. Turn the ignition switch to the “OFF” position for 30 seconds.
3. Turn the ignition switch to the “ON” position as in Step 1 for 11 minutes.
4. Turn the ignition switch to the “OFF” position for 30 seconds.
5. Turn the ignition switch to the “ON” position as in Step 1 for 11 minutes for a third time.
6. Turn the ignition switch to the “OFF” position for 30 seconds for a third time.
7. Turn the ignition switch to the “ON” position for 30 seconds.
8. Turn the ignition switch to the “OFF” position.
9. Attempt to start the engine.
and yes you need to program it with the tech 2

yes that is the point.
like pressing the accelerator 3 times to reset oil life and other tricks you can do without the "correct" tools
programming with the tech 2 will marry all modules together

Far as I know that manual relearn works on all gm product from the 2000's
I've used it on a caddy a Chevy 1500 and a dmax it works.
