Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Freeze Frame Data
- FREEZE FRAME DATA
- Whenever a DTC is detected, the skid control ECU stores the current vehicle (sensor) state as Freeze Frame Data.
- The skid control ECU stores the number of times (maximum: 31) the ignition switch has been turned from OFF to ON since the last time the ABS was activated.
HINT:
- However, if the vehicle is stopped or at a low speed (7 km/h (4.3 mph) or less), or if a DTC is detected, the skid control ECU will stop counting the number.
- Freeze Frame Data at the time the ABS operates:
The skid control ECU stores and updates data whenever the ABS system operates.
When the ECU stores data at the time a DTC is detected, the data stored during ABS operation is cleared.
- Freeze Frame Data at the time a DTC is detected:
When the skid control ECU stores data at the time a DTC is detected, no updates will be performed until the data is cleared.
- CHECK FREEZE FRAME DATA
- Connect the Techstream to the DLC3.
- Turn the ignition switch to ON.
- Turn the tester on.
- Check the freeze frame data by following the prompts on the Techstream display.

- CLEAR FREEZE FRAME DATA NOTE: Clearing the DTC will also clear the Freeze Frame Data.
- Connect the Techstream to the DLC3.
- Turn the ignition switch to ON.
- Clear the DTC and Freeze Frame Data (See DTC CHECK/CLEAR ).

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
