If the Accessory Power Module will output current under a load but the voltage is low on both sides of the fuse when compared to the voltage output at the Accessory Power Module, check the following Service Information for any other Diagnostic Trouble Codes that may have led to the low voltage condition, Accessory Power Module output terminal is clean and torqued to specification, The Accessory Power Module output cable ring terminal is properly seated to the Accessory Power Module output terminal post and its condition, and test the voltage drop on the ground cables to the engine block, transmission, body and chassis to ensure they are within specification.
PIC5322D2017-08-15. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE. This Preliminary Information communication advises the technician of a customer concern where the heated seat indicator light is not functioning or the heated seats are not up to operating temperature during a remote vehicle start event. This is normal operation of the heated seat during a remote vehicle start event. The electronic climate control module is not in a complete wake up state during a remote vehicle start mode and will not enable the light emitting diode. After a cold soak below 32 degrees Fahrenheit the seat will not get hot in the 10 minutes or less of the remote vehicle start mode. This is due to the fact that the heat element is not in direct contract with the seat surface while the seat is unoccupied and the foam below the heater is full cold insulating air which takes time to heat up.
