INSPECTION PROCEDURE
HINT:
In contrast to normal malfunction diagnosis for components, circuits and systems, DTC P1604 is used to determine
the malfunctioning area from the problem symptoms and freeze frame data when the user mentions problems
such as starting difficulty.
If any other DTCs are output, perform troubleshooting for those DTCs first.
When the Data List item "Immobiliser Fuel Cut" is ON, the engine cannot be started.
Read freeze frame data using the Techstream. Freeze frame data records engine conditions when a malfunction
occurs. This information can be useful when troubleshooting.
