Inspection Procedure

2007 Scion tC Base, AutomaticSECTION Inspection Procedure
NOTE: The intelligent tester is required to conduct the following diagnostic troubleshooting procedure.

HINT:

  • Using intelligent tester monitor results enables the EVAP (Evaporative Emission) system to be confirmed.
  • Read freeze frame data using the intelligent tester. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can be helpful in determining whether the vehicle was running or stopped, whether the engine was warmed up or not, whether the air-fuel ratio was lean or rich, as well as other data recorded at the time of a malfunction (See FREEZE FRAME DATA  ).
  1. CONFIRM DTC 
    1. Turn the ignition switch off and wait for 10 seconds.
    2. Turn the ignition switch to the ON position.
    3. Turn the ignition switch off and wait for 10 seconds.
    4. Connect an intelligent tester to the DLC3.
    5. Turn the ignition switch to the ON position and turn the tester on.
    6. Select the following menu items: DIAGNOSIS / ENHANCED OBD II / DTC INFO / CURRENT CODES.
    7. Confirm DTCs and freeze frame data.

      If any EVAP system DTCs are set, the malfunctioning area can be determined using the table below.

      NOTE: If the reference pressure difference between the first and second checks is greater than the specification, all the DTCs relating to the reference pressure (P043E, P043F, P2401, P2402 and P2419) are stored.
