Action in service

Precondition: Engine off

1st step: -> Read out raw data [clutch 1 pressure sensor, clutch 2 pressure sensor]

Tolerance range:

0.2 bar < pressure < 1.8 bar

1st step: Case 1: Pressure in one of the / both clutches outside tolerance range 2nd step: Defective pressure sensor(s)

=> Replace E-module

1st step: Case 2: Pressure in both clutches within tolerance range 2nd step: => Continue with fault analysis

2nd step: Read out fault category

Precondition: Both transmission units in neutral, engine running

2nd step: Fault category 0, 2 (undefined, offset error): => Apply pressure to both clutches

Test routine 'Test_Offset_K1-2_02 '

2nd step: Case 1: Pressure difference </= 0.5 bar 3rd step: => Delete diagnostic fault code

2nd step: Case 2: Pressure difference > 0.5 bar 3rd step: Pressure sensor offset too high

=> Replace E-module

2nd step: Fault category 4, 8 (short circuit or open wire): Fault status

2nd step: Case 1: Persistent error 3rd step: Defective pressure sensor(s)

=> Replace E-module

2nd step: Case 2: Sporadic error 3rd step: => Delete diagnostic fault code
