Inspection Procedure

HINT:

Read freeze frame data using the Intelligent tester or Techstream. Freeze frame data records the engine condition when malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air-fuel ratio was lean or rich, and other data from the time the malfunction occurred.

1. CHECK ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P010F) 
   1. Connect the Intelligent tester or Techstream to the DLC3.
   2. Turn the engine switch on (IG).
   3. Turn the tester ON.
   4. Enter the following menus:
      1. Intelligent tester - Select: DIAGNOSIS / ENHANCED OBD II / DTC INFO / CURRENT CODES.
      2. Techstream - Select: Powertrain / Engine / Trouble Codes.
   5. Read DTCs.
