SOL ENOlD VALVES 
The following  tests are performed continuously  by a background  task. If a fault  is detected, it is filtered for a set period. 
When  filtering  ends a fault  code is stored in the TCM  and action  is taken  to ensure  the integrity  of the  system. 
During  limp home  mode the internal  relay is turned 
off to  remove  the supply  to the  solenoids  and the gearbox with default  to fourth  gear (if aforward  gear is alreadyselected) and third  gear (if P.R.N.). Selecting  N and  then D will engage 
3rd  gear  only. 
Each  test checks  that the feedback  from the output  stage module  is consistent 
with the  driven  state of the  solenoid 
output,  detects short circuit to ground,  short circuit to battery voltage and open  circuit.
