The hazard
Certain vehicles equipped with Peterbilt's SmartGage system containing a Reduced Function Interface Module (RFIM). This module receives data from various components/systems on the vehicle then sends the information to a microprocessor. A manufacturing defect in the RFIM's can allow water to penetrate into the pressure block portion of the module, causing an electrical short in the pressure transducer connector. his results in an erroneous air pressure reading on the gauge in the dash. Correction: The RFIM date code will be inspected and all RFIM's built prior to September 9, 2000 will be replaced.
