Focus mk1 1.8 TDDi immo problem.

[razor1199]

Hey,
I have problem with immo in this focus. There are 2 DTC's that i can't delete.
B2139 PCM ID does not match between the PCM and PATS control(PATS/ICM/VIC/HEC/SCIL).
B1681 Transceiver signal not detected.
I havwe put "new" transceiver from working focus, but there is still same problem. Voltages KL. 15 and 30 are good on ECU and on transceiver, grounds also. Wires between ECU and transceiver are good too.
Can it be ECU dead?

I thought keys needs to be programmed once again, but after delete keys I can't learn them again, cause ECU doesn't see transceiver unfortunately.
Any ideas?

dtc is in immo(PATS) or in ecu(PCM)? ecu can be checked by obd?

Immo is in ecu. Ecu from 1.8 tddi is visteon with pats inside. Check wires again! You have 2 wires from antenna to ecu. Look on autodata i dont remember the 2 pins! So check again the wiers. Check transceiver wires, check ground!

On tddi, you look led First adaptation key( you must have 2), and if auto not start and led blink, must adapt ecu pump(fip)

Ecu pump is adapted if pump is changed. Is not the case

@leotdx I have checked wires twice, they are ok, 2 pins between ECU and transceiver are ok.
@Pyromaniak they are in ECU, I have connected with it

ADVERTISEMENT:-

accorfing to to urban rumor a strap on soluaris can verginise the pump take 3/4 hour to do
where the wires terminate on aerial use xacto knife to press wires in

rumour states 4 wires, ground, ignition battery live (or another ignition) and one to the ecu who lives down the lane.

OFF TOPIC:/

dont think on focus but escort diesel wiring by air intake would chaff on front panel

I think it's worth reading

Okay, but what do you mean? I wrote in topic name Focus 1.8TDDi.
Exactly it's year 2000, EEC-V ECU. I don't need make dashboard correction or sth like that. I just want know possibilities of those trouble codes.

@Meat-Head thanks, I will bypass wires to ECU and see what's gonna happen. Ground and +12V on transceiver wires are stable

I thought someone had same case as me that's why I have asked for
Anyway, if I put new ECU and transceiver will I be able to program my original keys in second hand ECU (after erase)? How about pump? I mean is there any dependence in pump numbers and ECU numbers? Or I can put any ECU (ofc from this diesel) to this pump?

I have replaced pump many times and programmed it, but always had same pump numbers.
If I will buy different ECU numbers with keys, the pump should be coded successfully?

You have written "I think that it will not be indifferent, which ecu", I can't understand it well, language barrier. This means that I can put to this pump different ECU number (but from same diesel) ?
