#Not implemented. AmbientAirTemperature error
Check ambient air temp sensor for proper functionality. Check and correct trouble codes in the chassis to eliminate faults that may prevent the messages from beeing sent. If there are more fault codes for message or communication error, Check the CAN bus wiring on both sides of the chassis system's gateway and its power supply.
What you'll see
Functions dependent on the signal might be degraded. For example: - Engine shutsdown when it is very cold outside due to idle driver, even when configured to not do so. - Cooling might not start if ambient air temp is lower than should or if higher than actual, cooling might be run in too cold ambient temperature. - Evaporator gets frozen.
System reaction
Cooling might not start if ambient air temp is lower than should or if higher than actual, cooling might be run in too cold ambient temperature
Diagnostic depth
Cooling with ac not functioning when should or running in cold ambient temp.
A control unit is not communicating on the CAN bus or the messages are not passed through the chassis system gateway: Message Ambient conditions status from Chassis is not received.
