This computer will be programmed to your vehicle prior to shipment. **I do not program vehicles newer than model year 2007; I do not program GMC Acadia or Saturn.** After installation, security relearn may be required before the vehicle will start. This can typically be done with no special tools in 30 minutes. Some vehicles may display the check engine light for crankshaft position variation, which will require a relearn using a bidirectional scan tool. SKU: 22385 Category: Tag:
