Heated Seat Module

Two heated seat modules are used on each vehicle equipped with the heated seat option. One heated seat module is located on each seat cushion pan, where they are secured with two push-in type plastic fasteners. The modules are encased within a small, rectangular, molded plastic housing with a single connector receptacle that allows them to be connected to all of the required inputs and outputs through the power seat wire harness.

The heated seat modules are electronic microprocessor controlled devices that are designed to monitor the inputs and control the outputs of the heated seat system. The heated seat modules are programmed to provide two levels of heating for each front seat. The low temperature set point is about 97°F (36°C) and the high temperature set point is about 105°F (41°C). The heated seat modules are also programmed to perform some self-diagnosis. If the module detects a shorted or open heating element or a NTC heated seat sensor out of range the module will flash the heated seat switch indicator LED's, to inform the mechanic or operator that a problem exists with the heated seat system.

The heated seat modules cannot be adjusted or repaired. If a module is damaged or faulty, the entire module must be replaced.
