Section II Diagnosis & Fault Clearing
LF7162 air bag system can carry out self-diagnosis, and the basic diagnostic procedure is as
follows:
I. Self-diagnosis of SRS warning lamp circuit
1. Turn the ignition switch to position ACC or ON, and check SRS warning lamp for illumination.
2. The system is ok if the warning lamp keeps light for about 5s and then dark for over 5s.
3. The continuous illumination of the warning lamp indicates that single fault or multiple faults have
been detected, then read out DTC and clear off the faults as per part II in this section.
4. If SRS warning lamp illuminates sometimes after connected with the ignition switch for 5s, or
SRS warning lamp illuminates again even the ignition switch has been turned to position LOCK,
check SRS warning lamp circuit for short circuit as per Section 2.5.
