2nd Row

DESCRIPTION





The two momentary, bidirectional rocker-type heated seat switches (2 and 3) provide a resistive multi-plexed signal to the Heated Seat Module (HSM) via a hard-wired mux circuit. Each switch has a center neutral position and low and high position so that both 2nd row seat passengers can select a preferred level of seat heating. Each heated seat switch has two Light-Emitting Diode (LED) indicator lamps (4 and 5), which indicate the selected mode (low or high) of the system. These indicator lamps also provide diagnostic feedback for the 2nd row heated seat system. Each switch also contains an incandescent bulb, which provides back lighting of the switch when the headlamps or park lamps are on.

The heated seat switches are both mounted in the 2nd row seat center console. The two switches are snapped into mounting holes in the console switch bezel (1). The heated seat switches are differentiated by the keyway in the electrical connector receptacle on the backs of the switches and a keyway on the switch housing. The wire harness connectors for the heated seat switches are keyed to match the connector receptacles on the switches so that the two heated seat switches can only be connected to the proper heated seat electrical.

The two LED indicator lamps and the incandescent bulb in each heated seat switch cannot be repaired. If the indicator lamps or back lighting bulb are inoperative or damaged, the individual heated seat switch must be replaced.
