End of test



2. Check component B11/4 (Coolant temperature sensor).



Test 2.1: Check component B11/4 (Coolant temperature sensor) using actual value.



Test 2.2: Check signal lines on component B11/4 (Coolant temperature sensor).



Test 2.3: Check internal resistance of component B11/4 (Coolant temperature sensor).



2.1. Check component B11/4 (Coolant temperature sensor) using actual value.



Test prerequisite



- The actual value is not o.k.
