Freeze Frame Data [11/2017 - 12/2018]
- DESCRIPTION
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 recorded at the time of a malfunction.
HINT:
- If it is impossible to replicate the problem even though a DTC is detected, confirm the freeze frame data.
- Freeze frame data is available in long and short forms.
- PENDING FREEZE FRAME DATA
HINT:
Pending freeze frame data is stored when a 2 trip detection logic DTC is first detected during the first trip.
- Connect the Techstream to the DLC3.
- Turn the power switch on (IG).
- Turn the Techstream on.
- Enter the following menus: Powertrain / Engine / Trouble Codes.
- Select a DTC in order to display its pending freeze frame data.
Powertrain > Engine > Trouble Codes
HINT:
- Pending freeze frame data is cleared when any of the following occurs.
- Using the Techstream, the DTCs cleared.
- The cable is disconnected from the negative (-) auxiliary battery terminal.
- 40 trips with the engine fully warmed up have been performed after returning to normal. (Pending freeze frame data will not be cleared by only returning the system to normal.)
- With previous pending freeze frame data stored, if pending freeze frame data is newly stored when a 2 trip detection logic DTC is detected in the first trip, the old freeze frame data will be replaced with the new data of the newly detected DTC in the next trip.
- Pending freeze frame data is cleared when any of the following occurs.
