Step 4, Immobilizer Bypass Modules

Most newer vehicles have a factory engine immobilizer system

designed to prevent any unauthorized use of the vehicle. These

immobilizers will cut off power to the starter and the fuel supply

preventing a thief from starting the vehicle.

There are several types of immobilizers, with the most common

being the resistance-based passlock/passlock 2 systems found on

most newer GM vehicles. This system can be bypassed using the

20402, 29402 or 556L immobilizer bypass modules available at

your local authorized retailer or at www.directedstore.com. The

majority of transponder-based immobilizer systems can be

bypassed using the 20402, 29402 or 556U immobilizer bypass

module available at your local authorized retailer.

The WHITE/BLACK wire of the 6-pin harness supplies a 400mA (-)

output as soon as the control module begins the remote start

process. This wire can be used to activate an immobilizer bypass

unit.

To determine which bypass module your vehicle requires, use the

website Interface Module Look-Up tool at

www.autocommand.com.

note! Any vehicle equipped with a factory immobi-

lizer must use an immobilizer bypass module to

remote start. If not used, the vehicle ignition or

fuel supply circuits could lock up and require a

costly trip to the dealer to reset the computer sys-

tem.
