Inspection Procedure

HINT:

Read freeze frame data using Techstream. The ECM (included in the hybrid vehicle control ECU) records vehicle and driving condition information as freeze frame data the moment a DTC is stored. 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 P0121) 
   1. Connect Techstream to the DLC3.
   2. Turn the power switch on (IG).
   3. Turn the tester on.
   4. Select the following menu items: Powertrain / Engine / Trouble Code.
   5. Read the DTCs.
