Immobilizer System: Programming: Notes

NOTE: Ensure a valid key is available when replacing PCM or immobilizer unit, or both components will require replacement. When replacing an immobilizer system component, all working keys need to be reprogrammed into system. Replacing PCM or immobilizer unit will erase previously programmed key IDs.
