This computer will be programmed to your vehicle prior to shipment, so please send a message with your vehicle's 17-digit VIN promptly after buying. After installation, the security relearn may be required before the vehicle will start. This takes 30 minutes with no special tools. Some vehicles may turn on the check engine light for crankshaft position sensor variation, which requires a relearn using a bidirectional scan tool.
