Section 150 (Engine Immobilizer Systems): Programming: Notes
WARNING: This page is about a different car, the 2002 Toyota Avalon. However, it is still accessible from the selected car via links, so may be relevant.
Four different programming modes are provided for the engine immobilizer system.
- Key Registration In Automatic Registration Mode
Replacement Engine Control Modules (ECM) are in this program mode upon receipt from manufacturer. When original ECM is replaced, the new ECM MUST be programmed with the existing ignition key identification codes. - Registration Of Additional Master Key
This mode allows up to seven more master key identification codes to be registered with ECM. - Registration Of Additional Sub-Key
This mode allows up to three more sub-key key identification codes to be registered with ECM. - Erasing Ignition Key Identification Codes
This mode erases transponder key codes from ECM memory.
