With Heated And Cooled seats (RPO KB6)



The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

Condition/Concern:

Some customers may comment that the heated or cooled seat feature is inoperative for either the driver or passenger front seat. The cause may be a poor connection at the climate control seat module (CCSM) C1 pin E circuit 4740 (2007 model year) or X1 pin E circuit 4740 (2008 model year).

Recommendation/Instructions:

Closely inspect CCSM C1 pin E or X1 pin E for proper pin fit. Also check for any distortion of the connector housing or CCSM that could cause a poor connection. If any distortion is found, replace the CCSM and connector.

Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.
