   CHECK GEARBOX warning lamp on.
   
   
  
  
   TCM in Limp-Home mode.
   
   
   
    Conditions
   
  
  
   Slippage time during shifting exceeds 1.3 s or is below 0.3 s.
   
   
   
    Diagnostic help
   
  
  
   There is normally some degree of slippage in the torque converter and in clutches and brakes during engagement. The control module stores the slippage time. The fault primarily indicates a mechanical defect. The mechanical components in the transmission are so worn that the control module adaptation is lost.
   
   
   
    Diagnostic procedure
   
   
    1 Check the fault symptom
   
   
     
   
   
  
  
   Check the problem by driving the car following
   
    Test drive schedule
   
   . Note any fault symptoms.
   
   
   
    Are there any fault symptoms?
   
   
   
    
     Continue with
     
      Mechanic and hydraulic faults
     
     and then with step 2.
     
     
    
   
   
   
   
    
     Continue with step 2.
     
     
    
   
   
   
    2 Final check
   
   
     
   
   
  
  
  
   
    
     
      | - | Clear all diagnostic trouble codes in the system. 
 
 | 
    
   
  
  
   
    
     
      | - | Perform a driving cycle: 
 
 | 
    
   
  
  
   
    
     
      |  | • | Drive the car at varying loads and engine speeds for 5 minutes. 
 
 | 
    
   
  
  
   
    
     
      | - | Evaluate the driving cycle: 
 
 | 
    
   
  
  
   
    
     
      |  | • | Make sure the trouble code has not recurred. 
 
 | 
    
   
  
  
  
   Has the trouble code recurred?
  
  
  
   
    Continue with
    
     Diagnostic procedure before replacing control module
    
    .
    
    
   
  
  
  
  
   
    The steps taken to rectify the fault were correct.
