DIAGNOSTIC TROUBLE CODE OUTPUT

The SRS-ECU diagnoses the following items and 
stores a diagnostic trouble code in the non-volatile 
memory (EEPROM*

1

) when a problem is detected. 

Therefore, the memory is not deleted after a battery 
terminal is disconnected, (The diagnostic trouble 
code memory can be deleted by the scan tool.)

CODE NO.
