[8] Check component B11/4 (Coolant temperature sensor).: The temperature difference between component B11/4 (Coolant temperature sensor) and component B1 (Oil temperature sensor) is implausible.

Test 1: Check component B11/4 (Coolant temperature sensor).

1. Check component B11/4 (Coolant temperature sensor).
Check actual value B11/4 (Coolant temperature sensor).
Note

- If fault exists, vehicle continues operating with substitute value from the temperature model.
Test prerequisite

- Switch on ignition.
Status of the relevant actual values:
- Coolant temperature:Warning! Communication with ECU required.

- Oil temperature:Warning! Communication with ECU required.
Specified value

- The actual values must be plausible.
- If the connection is unplugged at component B11/4 (Coolant temperature sensor), the value is approx. -40° C.
Question

- Are the actual values o.k.?


YES
The actual values are okay.Further procedure

- Test wiring and plug connections between control module N3/9 (CDI control unit) and B11/4 (Coolant temperature sensor) for Loose contact, repair or replace if necessary.
End of test

NO
The actual values are not plausible.Possible cause and remedy

- Replace component if its value is implausible.
End of test
