Freeze Frame Data [12/2019 - ]

WARNING: This page is about a different variant/trim than selected.
  1. FREEZE FRAME DATA 
    1. When a DTC is stored, the 4WD ECU assembly stores the current vehicle state as Freeze Frame Data.

      HINT: 

      Freeze Frame Data at the time a DTC is stored:

      • When the 4WD ECU assembly stores data at the time a DTC is stored, no updates will be performed until the data is cleared.
      • "Number of IG ON" is not stored as Freeze Frame Data.
  2. CHECK FREEZE FRAME DATA 
    1. According to the display on the GTS, select the trouble code data display with Freeze Frame Data.
