OPEL ISUZU 8971891360 (16267710 / 1.7L EDU) REPAIR SOLUTION

**uferi** · 2nd May, 2012, 06:42 AM

Dear forum members,
I want talk about these 3 chips on the board. I spent a lot of time to draw back the schematic circuit of this part of circuit (because I had problem with this part of circuit: the 5 Volt power supply for this circuit section was only ~3V, I measured the current consumption of this circuit on a good circuit and after that on the bad, some of the chips was bad). So, I think the circuit is a shift register (similar with the CD4014), BUT, the CD4014 is a 8 bit shift register with parallel load facility in 16 pin format, our chip have only 14 pins... The core of the chips is possible to have only 7 bits (reduced core), or possible the core with 8 bit shift register but reduced pin count (less output number for example).
I think, the sift registers is necessary for a "state machine" circuit, in function of the inputs and outputs, the state machine sets the next outputs.
Best regards,
Feri

Hi
I need help for the components that I have selected in red area. Do you have any info? On some parts I can read sAK 23 and on some parts I can read sAK 24. Have you any info, please?
Thanks a lot

In the picture in the lower right corner i have marked with a yellow dot a transistor. Does anybody know what type of transistor it is? On mine i can't read anything.

Very good post, thanks! I had this problem, but we solved it...

Hi !
I have a astra G Y17DT that"s when hot stop"s !
I resold the solder"s joint"s and still give me dtc p0251 from spill valve !
if I erase the dtc the car start"s but dies few seconds later !
anyone have a situation like this ?!

Look picture:

red line is short conect with wire if you not good +12 on coil or contact is burned then put wire.

other picture is shema, if I have problem I write shematic part then part.

Hi, and thanks all for this great forum

this one got water in
watch the pictures...
made it start 170mAmps consumption, 168.5 volt on inverter,
car doesnt start...
any sugestion apreciated

EDIT ! :
Found it, was my fault, shorted by mistake spill valve to ground
good thing is the ecu has protection
works like new

thanks,
cristi

Replace ecu...

**javierfichera** · 5th February, 2013, 05:27 AM

Dear Friends, any idea for this chip 014.
Thanks

same problem here
chip 3385 and 3382 are in short and I dont know what they are

any info apreciated

regards
cristi

maybe this or this

**javierfichera** · 6th February, 2013, 04:42 PM

3385, 3382 and the other is the same, I believe that I will test the circuit with LM339 or LM324 TSSOP, and will report in the next few days.............

lm324 in 14 pin capsule has + on pin 4 and gnd on pin 11
lm339 in 14 pin capsule has + on pin 3 and gnd on pin 12
datasheet search on google

circuits 3385 3384 and 3382 have + on pin 14 and gnd on pin 7(like most logic, ttl, cmos, whatever )

in have two boards with 3385, 3382 and 3385 , 3384 in
short circuit (about 12 ohm )

i have 3384 and 3382 in working condition (i hope so) but not
enough experience to find out what they are...
i've searched the net for 014 xxxx 338x but no results

thanks
