Help identify c53. part capacity Samurai ECM 33920-B0C70

[fixkick]

Thanks very much but I need to know about the smd blown parts near c53 .Your knowlege is big about this ECM and if You can tell me it is important part or not . Thanks any way

nobody knows this, 100 of ECU and not same in all countries, and some are radically different. vast ECU made for all countries, and there smog laws too, different.



smd

well the boric acid from C53 leaked and wrecked that and does happen but more rare



try 0.1uf at 50v.  (NOT POLARIZED LIKE c53)

nobody has schematics, zero. for sure all of them zero.



or buy a spare ecu and read top of SMD cap and use SMD cap decoder easy to find uf.



sammi did your read my ecu page

did you  read the slide show for sammi

https://fixkick.com/ecu

then slide show 30 photos mixed all USA> we are there,  and vitara ECU not thee same nor any sammi made  up to 1995 , what year is yours?

this is all I have on sammi, they are very rare now here, not seen one on the ROAD here in 10 years, I see side kick 1 time per month here ON THE public roads.


 ah my ERROR I zoomed your photo and C53 is SMD
and that cap filters the high frequency noses on the car 12vdc power (igniton on) bus.
50vdc is spec, or more.  car power can do huge spike up to there, for sure AC clutch  noise HUGE< if have AC, and spark noise too.
0.1uf or more.  0.2 or tad higher but no too high or will not fit on SMD pads.  this ECU does not have LDO VRMs, low dropout, so can fail with excess noise easy.

good luck. on fixing any old ECU.   all the big caps are no good, (electrolytic) this old if still are.
