Key on. If the fault is present, the

 

 

 

 

 

 

 

system should automatically detect the

 

 

 

 

 

 

 

problem and set the code. If the fault

 

 

 

 

 

 

 

is not present at key on, operate the

 

 

 

 

 

 

 

vehicle and attempt to duplicate the

 

 

 

 

 

 

 

driving conditions that triggered the

 

 

 

 

 

 

 

fault code. Possible triggers include

 

 

 

 

 

 

 

heat, vibration, and varying levels of

 

 

 

 

 

 

 

 

 

 

 

 

 

 

throttle demand. It may take up to 75
