Test H: The Driver/Passenger Climate Controlled Seat Module Does Not Respond To The Scan Tool
PINPOINT TEST H: THE DRIVER/PASSENGER CLIMATE CONTROLLED SEAT MODULE DOES NOT RESPOND TO THE SCAN TOOL.H1-H3:
H4:
Normal Operation
The driver/passenger climate controlled seat module communicates with the scan tool through the universal asynchronous receiver-transmitter (UART)-based protocol (UBP) network. Circuit 2077 (PK/LB) provides the network connection to the driver/passenger climate controlled seat module. The driver/passenger climate controlled seat module shares the UBP network with the driver seat module (DSM) and the electronic automatic temperature control (EATC) module. Voltage for the driver/passenger climate controlled seat module is provided by circuit 294 (WH/LB). Circuit 1205 (BK) provides ground.
Possible Causes
- Fuse
- Circuit 294 (WH/LB) open
- Circuit 1205 (BK) open
- Circuit 2077 (PK/LB) open
