    Honda have issues the following TSB #10-08-16 for the below Honda CR-V


    SRS warning light turned on.

    Due to improper manufacturing process of the power supply IC of the SRS unit, the passivation layer of the IC was not formed properly. During the vehicle usage, moisture could have entered into the IC metal layer, which can cause corrosion in the metal layer. If the metal layer corrosion progresses, cracks will
    occur in the IC and the IC output voltage will drop, causing the SRS warning light to turn on.

    Manufacturing process of the power supply IC was changed to form the passivation layer properly.
