Memory Seat Heaters, Fig.1:

6A.
a. Examine harness wiring, checking continuity between SCM connector Al pins 9 and 10. A resistance value of 1.5-3.2 Ohm should be recorded indicating all heating elements intact and thermostat closed.
b. Check continuity from Body Processor Unit (BPU) black 48-way connector B, pin 38 to center console seat heater switch module connector pin 5. Operate switch and check continuity from BPU black 48-way connector B pin 38 to ground.
c. Check continuity between cushion heater module and squab heater module pins; resistance values of 1.0-2.0 Ohm and 0.5-1.2 Ohm respectively should be achieved.
d. Check continuity from SCM connector B2 pin 2, through console switch LED to ground; a resistance value of 0-0.5 Ohm should be recorded.
