Malfunction judgment
1. Malfunction record (trouble code storage)
After the ECU performs the diagnostic test cycle in order to verify a malfunction, the SRS-ECU will store the
relevant code, the initial detection time, the final detection time, and the number of times it occurred in the
EEPROM.
The SRS-ECU can store 16 codes at most.
2. SRS-ECU approved trouble codes
No. Malfunction introduction Type code

airbag ECU
Trouble code transmission is completed the SRS-ECU outputs through the maintenance program's
serial data interface to the specified diagnostic instrument (X-431 diagnostic scanner).
3. Internal malfunction
The microcontroller can detect the following items not only when starting up detection, but also during the
diagnostic detection cycle.
(a) The ignition circuit triggers the transistor: The high-end transistor will be detected not only when starting up
