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.)
Diagnostic trouble
Code No.
