TEST DESCRIPTION

Steps 1-7:

Steps 8-17:

Steps 18-30:

Steps 31-35:

The numbers below refer to the step numbers on the diagnostic table.
4. This step tests the integrity of the heated seat switch signal circuit of the driver door module. If the fuse in the jumper wire opens when you perform this test, the signal circuit is shorted to battery voltage.
5. This step tests the integrity of the ground circuit of the heated seat switch.
7. This step tests the integrity of the ground circuit of the heated seat module.
10. This step tests the integrity of the heated seat High/Low signal from the rear integration module. This signal is a momentary 35 millisecond one shot pulse signal that is monitored through a momentary voltage change in the volt meter when the switch is pressed. In order to accurately recognize the change in voltage, the volt meter should stable before performing this test.
