MEANING OF CODE:
SLIPPAGE AT CLUTCH K2
TCU calculates a differential speed at closed clutch K2. If this calculated value is out of range, TCU interprets this as slipping clutch.
• low pressure at clutch K2
• low main pressure
• wrong signal at internal speed sensor
• wrong signal at output speed sensor
• wrong size of the sensor gap
• clutch is defective
TCU REACTION:
TCUshifts to neutral
OP-Mode: limp home if failure at another clutch is pending TCU shifts to neutral
OP-Mode: TCU shutdown
POSSIBLE REPAIR STEPS:
check pressure at clutch K2
• check main pressure in the system
• check sensor gap at internal speed sensor
• check sensor gap at output speed sensor
• check signal at internal speed sensor
• check signal at output speed sensor
• replace clutch
