Pinpoint Test N : One Or Both Climate Controlled Seats Are Inoperative: Notes

WARNING: This page is about a different car, the 2015 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.

Refer to Climate Controlled Seats for schematic and connector information.

Normal Operation and Fault Conditions

The SCME is supplied voltage at all times, but the climate controlled seat system only operates with the engine running. The system can be operated with the ignition ON engine OFF by using a scan tool to bypass the climate controlled seat buttons on the touchscreen interface. When commanding a heat or cool mode operation in this manner, it only operates in 15 second intervals. Both voltage supply circuits are spliced together internal to the SCME, so if one circuit becomes open, both seats can still be operated. However, if a fault occurs setting a DTC specific to either climate controlled seat, only the affected seat is disabled by the SCME.

Possible Causes

Wiring, terminals or connectors
FDIM
FCIM
SCME

Visual Inspection and Diagnostic Pre-checks
