Heated Seat Module: Description
One heated seat module is used per vehicle to control both front heated seats. The heated seat module (Fig. Fig 1 ) is located on the passenger seat cushion pan, where it is secured with two push-in type plastic fasteners. The module is encased within a small, rectangular, molded plastic housing with a single connector receptacle that allows it to be connected to all of the required inputs and outputs through the power seat wire harness.
The heated seat module is a electronic microprocessor controlled device that is designed to monitor the inputs and control the outputs of the heated seat system. The heated seat module is programmed to provide two levels of heating for each front seat. The Low temperature set point is about 36°C (97°F) and the High temperature set point is about 41°C (105°F). The heated seat module is 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. Refer to DIAGNOSIS AND TESTING - HEATED SEAT MODULE for additional information.
The heated seat module cannot be adjusted or repaired. If a module is damaged or faulty, the entire module must be replaced.
