The areas to be sealed must be thoroughly cleaned before applying the RTV Silicone Sealer. Failure to properly clean and prepare the surfaces
to be sealed may result in an ineffective seal which could allow moisture to enter the PCM case.

The following procedure applies to original or new PCMs using a shop cloth, spray "brake clean," P/N 12377981 or the equivalent, onto the shop
cloth (do not use Carb Cleaner, as it will leave an oil residue). Clean the areas to be sealed on the PCM (do not spray directly onto the PCM).
Apply RTV silicone sealer, P/N 12345739 or the equivalent, to the entire perimeter of the PCM case, the screws and any areas where water may
enter the case of the PCM. Apply the RTV silicone sealer to the KS (knock sensor) module or EPROM access cover and allow to setup before
reinstalling in the vehicle.
