[fixkick]

Ok thanks!

My vin number is JSAETA01V00108621,Suzuki made in Japan.

Code 25 for Holland.

ECU number 33920-60A70
E2T40671
9316B

TESTS:


The fuse box with fuse diag- CEL not blinking,ON all time.
The front of battery connector 4 pins jmping B+C with paper clip, CEL not blinking ON all time;
Fuse box + 4pins connector B+C not blinking.

Unplugging ECU green connector lamp goes out.

i dont have 6 pins connector near battery.

TPS: gray-red + battery minus, key on-5V OK!

PIN A15 + ground not blinking................

My ECU is dead ?
seems yes. we now know the lamp works, and you have both DTC diag, connections, one at Fuse, and one at 4pin DLC near battery.
this is very common setup for real Japan made Vitara, (not CAMI, canada made)



I not replaced the capacitor C2 47uF 10V orange colour.... 50v, 60v, 63v, 75v or 100v ok but never ever 10v. 1
the best cap is (LOW ESR, cap, and is 105 deg. C rated, not 85c. use the best cap you can buy here,
look of damage under the large cap. any seen is bad , show me it?

10v is no GOOD.
show photos of ecu, for sure that corner cap, it the connector side corner
do yo have signs of acid spills like my page shows.
seems to me the ECU is in backup mode, (means dead) and engine runs but is super rich burning fuel, smells and CAT CON.
some good and bad, see acid spills ...
