4. Trouble Identification
(1) Trouble Record (DTC storage)
When the circular diagnostic tests are involved in identification of a trouble, the SRS ECU (HAE2.5) will
store relevant codes, first/last diagnosis time and frequency of the trouble in EEPROM.
SRS ECU (HAE2.5) can store up to 6 troubles, low voltage trouble as well as two crash records (front
and side).
The transmit of the DTCs are carried out in the way that the SRS ECU£¨HAE2.5£©via serial data
interface of the maintenance procedures assign the codes to the diagnostic detector.
