Inspection Procedure
HINT:
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.
- CHECK ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P2111 OR P2112)
- Connect the Techstream to the DLC3.
- Turn the ignition switch ON and turn the tester ON.
- Enter the following menus. Powertrain/Engine and ECT/Trouble Codes.
- Read the DTCs.
