-IMPORTANT:

The 30 minute security relearn procedure will need to be done before the car will start with the replacement computer.   The manual procedure requires no tools except a battery charger or jumper cables from another vehicle. This is necessary because the key will be on for 30+ minutes.  It can also be done with a scan tool.  Some vehicles are more difficult to do than others requiring multiple tries using the manual procedure.  For these vehicles we recommend the use of a scan tool. 

IN SOME CASES:
A crankshaft variation relearn may need to be performed once the vehicle is
running. This will be evident if the check engine or service engine soon light comes on once the vehicle is running. You will need access to a scan tool to do this and clear any related trouble codes (Code P0315). If this is not available to you a repair shop will have to perform this and clear the related trouble code. The vehicle will run normal but the ”service engine soon”light will come on and a trouble code will be stored until this is resolved.

NOTICE:
Both of these procedures are the responsibility of the end user.  We sell engine computers programmed to your vehicle, it is the end users responsibility to to both the vehicle theft deterrent relearn and the crankshaft variation relearn to make the computer functional on the vehicle.

We can disable both of these for a small programming fee but it is not recommended unless all other options are unavailable as it will cause various dash light under certain circumstances.
