DESCRIPTION





Two heated seat switches are located in the center stack of the instrument panel. The switches are located on the outer edges of the Accessory Switch Bank Module (ASBM). The ASBM (3) is located just below the radio (1) and just above the heater and air conditioner controls (2) in the center stack area of the instrument panel. If either of the switches is damaged or inoperative the complete ASBM assembly must be replaced.





Each heated seat switch (4) provides a resistor-multiplexed signal to the instrument cluster, sometimes referred to as the Cab Compartment Node (CCN). Amber Light Emitting Diodes (LEDs) on the outside edge of each switch indicate the level of heat in use: Two LEDs are illuminated for high, one for low, and none for off. Pressing the switch once will select high-level heating. Pressing the switch a second time will select low-level heating. Pressing the switch a third time will shut the heating elements off.

The LED indicator lamps in each heated seat switch cannot be repaired. If the LED lamps are inoperative or damaged, or the switch is inoperative or damaged the complete ASBM assembly must be replaced, Heated Seat Switch - Removal.
