Inspection Procedure
NOTE:
- Inspect the fuses for circuits related to this system before performing the following inspection procedure.
- The Techstream is required to conduct the following diagnostic troubleshooting procedure.
HINT:
- Unit expression
- [kPa-a (mmHg-a)] denotes absolute pressure.
- [kPa-g (mmHg-g)] denotes absolute pressure (relative pressure).
- On the Techstream, convert the unit of measurement according to the inspection procedure.
- Using Techstream monitor results enables the EVAP (Evaporative Emission) system to be confirmed.
- Read freeze frame data using the Techstream. 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.
