This PI Supercedes To Include 2008 Model Year. Please Discard PIT3845B
The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition/Concern:
Some customers may state that their power liftgate (RPO E61) is inoperative in very cold weather below -14°C (6.8°F). The concern seems to go away when the temperature is warmer.
Recommendation/Instructions:
Currently, the Power Lift Gate Module (PLGM) software will not allow the liftgate to operate at temperatures below -14°C (6.8°F). Please do not replace any parts for this concern as this is a normal design of the power liftgate system. The power liftgate will release but will have to be manually opened and closed when below the cold weather parameter above.
Note: Some early built 2007 vehicles will not allow the power liftgate to release in the cold weather. If you experience this concern, update the power liftgate module using the latest software available on Tis-2-Web. This new software will allow the power liftgate to release at temperatures below -14°C (6.8°F)
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.
