Vehicle Stability Control System -- Freeze Frame Data |
| FREEZE FRAME DATA |
Whenever a DTC is stored, the skid control ECU (brake actuator assembly) stores the current vehicle state as freeze frame data.
The skid control ECU (brake actuator assembly) stores the number of times (maximum: 31) the ignition switch has been turned from off to ON since the last time the ABS/VSC was activated.
- HINT:
- If the vehicle is stopped or traveling at a low speed (7 km/h (4 mph) or less), or if a DTC is stored, the skid control ECU (brake actuator assembly) stops counting the number of times the ignition switch has been turned from off to ON.
- Freeze frame data at the time the ABS/VSC operates:
The skid control ECU (brake actuator assembly) stores and updates data whenever the ABS/VSC operates.
When the ECU stores data at the time a DTC is stored, the data stored during ABS/VSC operation is cleared. - Freeze frame data at the time a DTC is stored:
When the skid control ECU (brake actuator assembly) stores data at the time a DTC is stored, no updates are performed until the data is cleared.
| CHECK FREEZE FRAME DATA |
Turn the ignition switch off.
Connect the intelligent tester to the DLC3.
Turn the ignition switch to ON.
Turn the intelligent tester on.
Enter the following menus: Chassis / ABS/VSC/TRC / DTC.
According to the display on the intelligent tester, select the trouble code data with freeze frame data.

| CLEAR FREEZE FRAME DATA |
- NOTICE:
- Clearing the DTC also clears the freeze frame data.
Connect the intelligent tester to the DLC3.
Turn the ignition switch to ON.
Clear the DTCs (HILUX_TGN26 RM000000XHV0CGX.html).
