what is the meaning of the code 9cc3 is there a spot to check voltage or a plug i should be looking for or a blown fuse or blown fuses
Expert:  Chad Farhat replied 11 months ago.

no there is no fuse or plug to check ,when you replaced the air bag parts when you turn it on the system check all components if one fail the light will come on

code 9cc3 is passenger side seat pressure sensor malfunction .

was that door sensor replaced ?

was all the parts replaced new ?

how bad a hit we talking here was side hit on the driver ?
