Fault description
Direct Ozone Reduction Catalyst Temperature / Radiator
Coolant Temperature Correlation
Condition for fault identification
Test condition:
Coolant temperature > 86 锟斤拷C, Coolant temperature at
radiator discharge >40 锟斤拷C --> meaning thermostat is
certainly open and the EAC sensor in valid temperature
range
Terminal condition: none
Voltage condition:
UBatt >10 V
Condition for fault memory entry
at least twice (more often as required) Drive at least 30 sec.
as during acceleration from rest in urban traffic
Action in service
