SRS-ECU
SUPPLEMENTAL RESTRAINT SYSTEM (SRS)
52B-12
NOTE: *
1
: Electrically Erasable Programmable ROM
*
2
: This diagnostic trouble code memory will be automatically cleared from the memory and the SRS warning
light will be switched off when the system returns to normal condition.
*
3
: The diagnostic trouble codes will remain in memory and the SRS warning light will be switched off if the
system returns to normal condition.
DATA LIST OUTPUT
When the SRS-ECU detects a problem, it stores a
diagnostic trouble code and the duration that the
problem has lasted in the non-voltage memory. In
addition, how often a diagnostic trouble code and
duration are cleared by the scan tool are stored in
the non-volatile memory as a reference for service
work. This data can be read by the scan tool.
