CTS V6-3.2L VIN N (2003)
1.
Adjust the front seat assembly to the maximum up and rearward position in order to access the heated seat control module electrical connector.
2.
Disconnect the heated seat control module harness gray, 6-way connector C2.
3.
Measure the front seat heat element total resistance between cavities A and C. Does the resistance measure less than 5 ohms?
^
If yes, go to Step 4.
^
If no, go to Step 5 in order to determine which of the three seat heat elements has a resistance value NOT within the specified range.
Important:
If the resistance is measured with the seat still warm, the resistance may vary outside of the specified range since the thermistor resistance
varies with temperature.
4.
Measure the front seat heat element thermistor resistance between cavities D and F. Does the resistance measure between 850 ohms and 11.5 K
ohms?
