continuous/steady blinking (e.g. on/off/on/off/on/off... and so on) means that there are no fault codes stored.

It can mean the protocol stored in the diagnostic reader is not the same as what the engine needs to communicate the codes.

the OP's car does not support your usual OBD2 diagnostic reader as it pre-dates OBD2. Instead the system uses the ECU light on the dash to output codes:
