FREEZE FRAME DATA
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 moving or stationary, whether the engine was warmed up or not, whether the air fuel ratio was lean or rich, as well as other data stored at the time of a malfunction.
CHECK DATA LINK CONNECTOR 3 (DLC3)
Check the DLC3.
CHECK BATTERY VOLTAGE
If the voltage is below 11 V, replace or recharge the battery before proceeding to the next step.
