Component Y110 (Three-disk thermostat valve) has a short circuit to ground. (P0598)
Possible cause:
- Y110 (Three-disk thermostat valve)
Affected functions:
- Heating
- Engine cooling
-------------------------------------------------
Test 1: Check component Y110 (Three-disk thermostat valve).
1. Check component Y110 (Three-disk thermostat valve).
Test 1.1: Component Y110 (Three-disk thermostat valve) is mechanically damaged or it sticks.
Test 1.2: Test current consumption of component Y110 (Three-disk thermostat valve).
1.1. Component Y110 (Three-disk thermostat valve) is mechanically damaged or it sticks.
Test 1.1.1: Y110 (Three-disk thermostat valve) : Coolant temperature is not reached.
Test 1.1.2: Y110 (Three-disk thermostat valve) : Coolant temperature is too high.
1.1.1. Y110 (Three-disk thermostat valve) : Coolant temperature is not reached.
Warning!Communication with ECU required.
1.1.2. Y110 (Three-disk thermostat valve) : Coolant temperature is too high.
Warning!Communication with ECU required.
1.2. Test current consumption of component Y110 (Three-disk thermostat valve).

Warning!
- Connection A of test cable 108 may NOT be connected to connection B of the 126-pin socket box (050).
Continue to test with button F2
Test sequence
- Measure direct current with multimeter between sockets [F.4] 100 and [M.54] 54 of the 126-pole socket box tester.
- Switch on ignition.
Specified value
- Amperage[0.6...1.2] A
Question
- Is the measurement value OK?
YES
The measurement value is OK.End of test
NO
The measurement value is not OK.Possible cause and remedy
- N10/1f57 (Fuse 57)
- N10/1kR (Circuit 87 relay, engine)
- Check lines from component N3/10 (ME-SFI [ME] control unit) to component Y110 (Three-disk thermostat valve).
- Y110 (Three-disk thermostat valve)
