temperature does not increase 0.5°C (0.9°F) within 300 seconds after the DEF tank coolant
valve has been commanded on.
MONITORED PARAMETER:
DEF tank temperature.
TYPICAL ENABLING CONDITIONS:
Coolant valve commanded open, coolant temperature.
MONITOR SEQUENCE:
None
EXECUTION FREQUENCEY:
Continuous when enabling conditions met.
TYPCIAL DURATION:
30 minutes
DASH LAMPS:
MIL
VERIFICATION:
Parked regeneration
POSSIBLE CAUSES:
1. Coolant valve stuck closed.
2. Lack of coolant flow to the coolant valve.
3. Faulty DEF tank temperature sensor.
