Seat Heater Switch: Description and Operation
Switch-Heated Seat
Description
HEATED SEAT SWITCH
The heated seat switches are both mounted in the instrument panel. The two switches are snapped into mounting holes in the instrument panel center
bezel (1). The two heated seat switches (2) and (3) are identical in appearance and construction, except for the location of a keyway in the connector
receptacle on the back of each switch. The instrument panel wire harness connectors for the heated seat switches are keyed to match the connector
receptacles so that the two heated seat switches can only be connected to the proper heated seat.
Each momentary, bidirectional rocker-type heated seat switch provides a resistor-multiplexed signal to the Cab Compartment Node (CCN). Each switch
has a center neutral position and momentary Low and High positions so that the driver and the front seat passenger can select a preferred seat heating
level. Each heated seat switch has two Light-Emitting Diode (LED) indicator lamps, which indicate the selected level (Low or High) of the seat heater.
Each switch also has one indicator lamp for back lighting of the switch when the ignition switch is in the Run position.
The five LED indicator lamps in each heated seat switch cannot be repaired. If the LED lamps are faulty or damaged, or the switch is faulty or damaged
the individual heated seat switch assembly must be replaced.
Operation
HEATED SEAT SWITCH
The heated seat switches receive battery current through a fused ignition switch output (run) circuit when the ignition switch is in the On position.
Depressing the heated seat switch rocker to its momentary High or Low position provides a hard-wired resistor multiplexed signal to the Cabin
