As initially, the write data is set when the on diagnostic cycle enable (IB1 D6
= 1), the turn on
diagnosis can be available for repeated use by sending the read command repeatedly after the initial
set up as shown as Figure 5.
Therefore, it is useful to check number of cycles from Power ON to the output appearance.
This IC has two built-in diagnostic modes dependent on the Turn-on timing.
A) Normal mode (one shot) of Turn-on diagnostics (data of IB1, D7
= 1)
B) Repeatability mode of Turn-on diagnostics (data of IB1, D7
= 0)
A) Normal mode (one shot diag.)
For example, if you want to get two valid readings, you have to send the command to read three
times.
True data are second data and third data.
The Data just received was detected
on the previous diagnostic cycle.
This is trigger to enable the
diag cycle.
Diag cycle with Turn-ON
When “Diag enable” goes
high, “Latch” is reflected at the
“Fault event”.
For example
Short Load, Open Load etc.

You have to read for an
interval of 150 ms or more to
get a valid reading.
Writing
(diag cycle enable
= 1)
(stand by OFF
= 0)
