For 1990-2009 cars

### Conditions for Setting the DTC

DTC P0571 will set if the vehicle speed has cycled from 0-60 km/h (0-37 mph) 5 times without seeing a change in the brake status.

If DTC P0571 sets and there is no code DTC P0572 or DTC P0573, then the PCM has failed internally.

### Test Description

Verify DTCs P0572 and P0573 are not present. If either are present, refer to these DTCs first. If no DTCs are present, replace the PCM.
