fault?

Set phone to LOCAL

mode. Is it OK?

Measure VSIM voltage

from X386. Is it ~3.0V?

Check VSIM-line

(X386,C390,R386,C203).

If OK, change R388.

If still fail, change UEM.

Yes

End

Yes

Check BSI-line including

X100,C100,C240,R202 and

R206. If OK, change UEM.

Change UPP

Check SIM power-up

sequence. Is it OK?

Yes

Check SIM lines (X386). If

OK, change R388. If still fail,

change UEM.

Yes

R388,

R206, R310. If

,change

UEM
