The hazard
On certain vehicles water intrusion could occur, and corrode and damage inside of the Signal-detect and Activation Module (SAM) Chassis. This corrosion could cause electrical shorts or intermittent operation of trailer tail lamps, trailer stop lamps, trailer side marker lamps and trailer lighting. Failure of the stop lamps to illuminate when the brakes are applied may result in following road users being unaware of the driver's intentions, increasing the risk of a crash causing property damage and/or personal injury. Also, under certain conditions, an electrical short in the Chassis SAM could also cause melting in the SAM or other electrical components, which could result in a vehicle fire. Correction: Dealers will inspect the Signal-detect and Activation Module (SAM) Chassis for evidence of corrosion and proper drip loop wire routing, and SAM Chassis damaged by corrosion will be replaced. A drip shield will be mounted inside the cab over the SAM chassis if not previously installed.
