  1. Ignition ON, observe the DTC information with a scan tool. DTCs P0A1F, P1A01, P1A05, and P1A06 should not set.
  2. Operate the vehicle within the Conditions for Running the DTC to verify the DTC does not reset. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records data.
