TAS6584-Q1: manual DC load diagnostics time

Toshiro Imi

Part Number: TAS6584-Q1

Tool/software:

Hello,

Our customer has a question diagnostics time from accessing State Control Register 0x3, 0x4 to wirting diagnostics result into 0xC0 to C2 register.

Does this depend on LDC BUFFER WAIT TIME, LDG RAMP1/2, LDG SETTLING 1/2 SETTING ?

Could you help our customer how long he has to wait for the duration.

Best regards,

Imi,

The DC diag will takes 155ms to finish, it depends also on ramp/settling settings. A reliable way is to check status of 0x72 and 0x73 see if the DC diag already finished.

Yao,

Does the number 155ms include ramp/settling time ?

It seems to take 155ms typ when no fault found. How about fault case ? Does it take longer ?

Can you also tell us TDC_DIAG max number ?

regards,
