in the ECU itself or in system circuits.
The DTCs can be read through the DLC3 of the vehicle. When the system seems to
be malfunctioning, use the Techstream to check for malfunctions ...
Engine does not Start but Initial Combustion Occurs
DESCRIPTION
If the key ID codes of the key and transponder key ECU assembly match, the engine
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.
