DIAGNOSTIC FUNCTION


CENTRE DIFFERENTIAL LOCK LAMP

When a problem occurs in the transfer or rear differential lock system, the 2WD/4WD operation indicator lamp (a), the centre differential lock lamp (b) or rear differential lock lamp (c) flashes rapidly (twice per second).
When the centre differential lock lamp (b) or rear differential lock lamp (c) is flashing rapidly, check the diagnosis output.

FREEZE FRAME DATA CHECK


Various data of when the diagnosis code is determined is obtained, and the status of that time is stored. By analysing each data using the M.U.T.-III, troubleshooting can be performed efficiently.
Display items of the freeze frame data are as follows.
