Go to Step6

Go to Step4


4

Important:The body control module (BCM) is programed to supply voltage to the heated seat switch only while the engine is running.
[ol]Disconnect the heated seat switch connector.
Connect a test lamp from the ignition voltage supply circuit terminal in the harness connector to a ground. [/ol]
Does the test lamp illuminate?



Go to Step5

Go to Step17


5

Connect the test lamp from the ignition voltage supply circuit terminal to the ground circuit terminal in the heated seat switch harness connector.
Does the test lamp illuminate?



Go to Step22

Go to Step18

[ol]Using a test lamp backprobe the seat heater element supply circuit terminal in the heated seat relay connector.
Operate the heated seat switch in the HIGH position. [/ol]
Does the test lamp illuminate?



Go to Step12

Go to Step7


7

[ol]Disconnect the heated seat relay.
Connect a test lamp from the heated seat switch signal circuit terminal in the harness connector to ground.
Operate the heated seat switch in the HIGH and LOW positions. [/ol]
Does the test lamp illuminate in the HIGH and LOW switch positions?



Go tostep 8

Go to Step15


8

[ol]Turn OFF the ignition.
Connect a test lamp from the battery positive voltage supply circuit terminal in the heated seat relay harness connector to ground. [/ol]
Does the test lamp illuminate?



Go to Step9

Go to Step19


9

Connect a test lamp from the battery positive voltage supply circuit terminal to the ground circuit terminal in the heated seat relay harness connector.
Does the test lamp illuminate?



Go to Step10

Go to Step20


10

Test the resistance from the heated seat thermistor signal circuit terminal to the ground circuit terminal in the heated seat relay harness connector.
Is the resistance within the specified values?

7K-11KΩ

Go to Step11

Go to Step14


11

[ol]Measure the resistance through the heated seat switch from the heated seat switch signal circuit terminal to the heated seat switch high/low signal circuit terminal in the heated seat relay harness connector.
Operate the heated seat switch in the HIGH and LOW positions. [/ol]
Is the resistance at or near the specified values?
