The Pro Module is to be installed at the Body Control Module. The BCM is attached to the fuse block under the second row seat on the drivers side.

We need to use wires from the 2 main connectors, first is the C1, a 24 pin grey connector,

And a 32 pin Tan connector as C2.

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 the switches as in the photo here below:

Passlock

Connect as following:

PRO Module
CAR Wires
RED
(together with PRO Module WHT wire): Find the Red/white or White wire in Connector C2 pin E9 and perform a 3 wire splice.
WHT
(together with PRO Module RED wire): Find the Red/white or White wire in Connector C2 pin E9 and perform a 3 wire splice.
BLK
the black needs to be connected to a chassy ground a bolt that goes to the floor area is a good ground
PPL
Not Used
GRN
Not Used
YEL
Find the yellow wire in Connector C1, Pin B10. Cut that yellow wire, and attach the yellow wire from the pro module going into that wire that goes to the BCM. Tape the other side that will remain unconnected.
BRN
find the Black wire in Connector C2, Pin E8, and perform a 3 wire splice.

Relearn Procedure

  1. Turn the key on, with the engine OFF.
  2. Try to start the engine, then release the key to ON, Engine will not start.
  3. Watch the security telltale, after about 10 mins, it will turn OFF.
  4. Turn OFF the ignition, and wait 5 seconds.

Repeat steps 1 through 4 two more times for a total of 3 cycles/30 minutes. You must turn the ignition OFF for 30 seconds before attempting to start the vehicle after the 3 cycles. Then start the engine .

Troubleshooting

  1. Make sure connector’s pinout and wiring colors of your car are both matching exactly those of our instructions. If not, please Submit a Request to our support team with details of the pinout and wiring colors in your car.
  2. Is the light on the side of the PRO module turning on? If not check power between RED and BLK wires of the PRO module installed and with the key in the ON position (you can use a power-meter or a light) and Submit a Request to our support team with results of the measurement.​
  3. If (1) and (2) are correct, is your vehicle cranking at all? Some systems are disabled due to the nature of the Passlock system and the specifics of the year. If your vehicle is not cranking, see if the starter relay (often in the under hood fuse block) clicks with the key turned to crank. You will need a second person to turn the key to crank while holding your finger on the starter relay.
  4. After you perform this test, or if you need our help to find the starter relay in your car, please Submit a Request to our technical support team detailing the tests you have done and the results.
  5. If the car is cranking, but engine doesn’t start or sometimes starts but immediately dies then do the following:
    1. Make sure the YELLOW wire of the PRO bypass is correctly connected and the connection is tight, and that you cut only the wire or wires indicated in the instructions, and on the proper side of the splice.
    2. Open the cover of the PRO Module and make sure the switches SW1 and SW2 are set exactly as indicated in the instructions for your car model/year, otherwise change them accordingly. Try starting the car.
  6. If during the relearn the battery went dead, or you turned the key off too soon, do the following.
    1. Take the battery cables off the battery, hold the ends together for 10 seconds then attach them to the battery.
    2. Try the relearn again with a charger or booster attached so the battery doesn’t run down. Be sure to cycle the key fully to start each time, then only release it to run and wait the time indicated.
    3. Also be sure the key was turned off for more than 30 seconds afterwards.

If car is still not starting or if you have any questions or concerns please Submit a Request to our technical support team detailing the tests you have done and the results.


NOTE: when contacting our support team, please always indicate your car’s make, model and year.

Is the GM Security System (VATS, Passkey or Passlock) giving you problems?

Would you like to solve the problem permanently...

You are in the right place!

NEWROCKIES is #1 in the world. It was born to solve GM VATS System problems once and for all and it’s the only thing we do. Our PRO Module is a FULL VATS Bypass that gets rid of the system entirely, the Key part, the Lock part and the TDM (which is the brain of the system).
