5.  The maintenance operation must be started after 60 seconds following the removal of negative connection of

accumulator, wrap the negative with insulating tape for insulation.

Due to the capacitance in SRS-ECU to maintain certain power to make the safety airbag release within a certain time after the

power-off of accumulator, the operation must be started after a while to avoid any possible major damaging accident caused

by the safety airbag’s improper release.

6. The parts such as SRS-ECU, safety airbag module as well as clock spring should be removed off and well preserved

providing the temperature is high enough to cause any damage(above93¡æ) in the painting operation.

The failure codes must be debugged with the diagnostic scanner following the repairing of SRS safety airbag system so as to

make alarm lamp work functionally.
