Upa reads HC05 in the system, you do not have to unsolder.
Solder cables and connect the 9-pin connector. Remember to disconnect the VDD from the plate.

so disconnect chip at pin9 vdd from immo board
then solder wire on the pin9 of the chip and connect to pin 9 on upa?

update I get it solder all 9 wires to chip and attach to 9 pins on upa as shown in upa manual leaving chip in place but disconnect vdd pin from circuit board so its only attached to upa wire 9 is this right ? or do I attach to 9pin immo connector pins straight to upa ?



like below ?



thankyou for helping darek

Hello

right I soldered all 9 wires for hc05b6 as shown in upa manual
and lifted vdd pin from plate. tried to read but will not read.

so I ran voltage tests 2 pins came back as bad if I remove the 2 bad wires and rerun test they both come back as ok.

the first bad connection is pin 1 IRQ
the second bad connection is pin 6 PD3

is was gonna give up but I found some extra reference to these chips hidden away in upa folder

the 2 bad connections seem to be the same that are described in the files I found.

1 was a txt file just containing a few words : CUT PD3, IRQ, TCAP1
as 2 of these seem to be the same as my 2 bad connections. check screens below.

           

its got me wondering maybe these chips will read ive seen someone else about with same errors on similar chip.

any help info is appreciated.

Bad connected. Do this as a pdf. Read with power supply and repin jumper, everything is written in pdf format.
