Frame layout
Note
The frame layout is defined in the CANmod.temp DBC file
The temperature frame contains the Cold-Junction (ambient) temperature and four sets of thermocouple sensor status and temperature readings.
In the following TL (Top-Left), TR (Top-Right), BL (Bottom-Left) and BR (Bottom-Right) refer to the locations of the thermocouple sensor connectors (see Connector back)

2: Hot-junction (sensor) connection error
3: Hot-junction (sensor) range error
Note
A temperature should only be considered valid if the associated status is OK
