IMMOBILISER SYSTEM(w/o Entry and Start System) Engine does not Start but Initial Combustion Occurs

DESCRIPTION

If the key ID codes of the key and transponder key ECU assembly match, the immobiliser system is unset and the engine start permission signal is sent to the ECM. When the ID codes of the transponder key ECU assembly and ECM match, the engine starts.
