FREEZE FRAME DATA

FREEZE FRAME DATA

(a) Using the GTS, check the vehicle condition (ECU, sensor) when the brake system operates or a DTC is output.

CHECK FREEZE FRAME DATA WHEN DTC WAS STORED

HINT:

  • Freeze frame data is stored when a DTC is output.
  • Once freeze frame data is stored when a DTC is output, it is not updated or cleared until the DTC is cleared.

(a) Turn the ignition switch off.

(b) Connect the GTS to the DLC3 and turn the ignition switch to ON.

(c) Operate the GTS to enter the Trouble Codes.

    Break-In Period

    No special break-in is necessary, but a few precautions in the first 600 miles (1,000 km) may add to the performance, economy, and life of the vehicle.

    Do not race the engine. Do not maintain one constant speed, either slow or fast, for a long period of time. Do not drive constantly at full-throttle or high engine rpm for extended periods of time. Avoid unnecessary hard stops. Avoid full-throttle starts.
