sorry for the delay.............Greetings...... “Hi, I’m Don (akaCustomer and I look forward to helping you!”.Your best professional way is to contact:http://newrockies.com/as they have the best solutionORYou can try a 1000 ohm resistor & connect between the ORANGE / BLACK & YELLOW PassLock wiresYou need to cut the YELLOW wire in half & connect the Resistor to the Cut Half that does NOT go to the Key SwitchNOTE: Make sure you are on the "PASSLOCK wires", they will be the smaller "3" wires at the Ignition Switch ORANGE / BLACK, YELLOW & RED / WHITE.IF you need more information, please ask "prior" to Rating..

sorry.........all you posted was:Need to bypass my vats system???there was nothing else posted.........ByPass is done exactly as I postedThere is NO other type ByPass, as the BCM & the PCM has Internal Components that cannot be removedIF you have tried what I posted, then the BCM & / or the PCM needs replaced.

Customer: replied 1 year ago.
Can I buy them used?
Expert:  Don 'Mo Lurch' replied 1 year ago.
BCM or PCM is available at many Salvage Yards, but you will have to have them Programmed via GM Scan ToolYou may want to have yours Repaired, as there are a number of Repair / Rebuilders On-LineEither way it will not be cheap.You may also want to contact;http://newrockies.com/first & see what they think, prior to any repairs
Customer: replied 1 year ago.
Ware do I get a scan tool can you rent them
Expert:  Don 'Mo Lurch' replied 1 year ago.
Some Auto Parts Stores rent, with heavy deposit.You will be looking for "GM Tech 2" Scan ToolIF you are unfamiliar with operation, you may want a Local Shop do this, as you can cause issues in Programming
Customer: replied 1 year ago.
There are bypass modules out there that I can buy also may be I can look at that option they go for like $250
Expert:  Don 'Mo Lurch' replied 1 year ago.
The method I posted is the "same" as a ByPass Module, except with a ByPass Module your PassLock has to be working for the ByPass Module to get the "correct" Resistance reading / programming.
