READ AND SAVE OPERATION HISTORY
|
NOTICE:
- If the vehicle or vehicle controls are operated (for example, during initial
inspection when the vehicle is brought in for repair) before operation history
has been read out and saved, the operation history information could be lost.
- The function "Read operation history" uses the current system time setting
inside the Techstream and the time counter inside the controlling ECU to calculate
the timings shown in the operation history. For this reason, before reading
out the operation history, first make sure that the Techstream system clock
is accurately set to the current time.
(a) Read and save operation history using the Techstream.
