·   With ignition "ON" the fault is recognized immediately

·   Voltage control relay can be actuated, i. e. trouble codes 62, 63 and 64 not set

·   The voltage level recognized by the control unit at the relevant control unit output (terminal 43) is 12 V, although the output from the control unit was set to 0 V (solenoid valve is actuated) (short circuit to battery voltage)

·   Engine running

·   The fault must be recognized at least 8 times (160 ms).

 

·   If the fault occurs after the engine is started, the fault is only recognized after the solenoid valve is actuated

 

Effects:

·  Solenoid valves (brake band, 1 - 2 / 3 - 4 shifting, 2 - 3 shifting, torque converter clutch) and electrohydraulic pressure regulator are switched off

·   If the fault is recognized, the following gears can still be shifted manually in each driving stage (emergency program):
