Locate the BCM and install the PRO Bypass Module

The BCM is under the cluster and above the steering column. The knee bolster must come off, much of the trim on the dash and the cluster must come out to get at this to install the module.




There are 6 electrical connectors on the BCM (C1, C2, C3, C4, C5 and C6). We need C2 (Gray) C3 (Brown) and C4 (Light Blue).



If the enclosure of your NEWROCKIES PRO Module is green and blue, please setup the switches as following (if enclosure is black, please submit a request to our support team for correct switch configurations): 


Open the NEWROCKIES PRO Module's cover (this will NOT void the warranty) by removing the 2 screws on the bottom. Inside there are 2 sets of switches.


Set SW1 (8 switches) as following:

1 2 3 4 5 6 7 8
on off off off off on on off


Set SW2 (10 switches) as following:

1 2 3 4 5 6 7 8 9 10
off off off off off off off on off off

Perform the re-learning procedure

  1. Turn ON the ignition, with the engine OFF.
  2. Attempt to start the engine, then release the key to ON (vehicle will not start).
  3. Observe the SECURITY light, after approximately 11 minutes the light will turn OFF.
  4. Turn OFF the ignition, and wait 10 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 Sensor Data Code and/or passwords on the next ignition switch transition from OFF to CRANK).


Important: The vehicle learns the relearns 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.

Start the engine (the vehicle has now learned the Sensor Data Code and/or password).
