## NHTSA's summary

System Overviews \(7\-Digit PIN\): Replacing an instrument cluster or ECM requires additional steps in vehicles that are equipped with the immobilizer System. The instrument cluster and ECM communicate with each other constantly, and must recognize each other. If there is no recognition, the vehicle will start, but stall immediately. a 7\-digit pin is used to tell the existing components in the immobilizer system to recognize a new component and to communicate with it.
