This model Suzuki was marketed in Spain and as far as I can tell the system fitted is particular to Spain. It is SID 801 and has a coded immo keypad, like the old Peugeots. The engine is the usual 2.0 Peugeot one same as a 406 etc.

The wiring to the keypad is damaged (pulled out of the plug). The customer has never had to use the keypad to start the car. It looks like it has not worked for a long time so I assume at some stage the code was entered and the unit unplugged. Someone had stripped this before I saw it. The battery was also removed for charging.

Scan tools used –
KTS, system not listed as a Suzuki. Going in as a Peugeot or Citroen it fails to ID it and only gives codes.
Carman, also not listed under Suzuki, gives codes and data.
DEC, going in as Peugeot and selecting SID801 gives codes and what seems to be good data (matches what is on the scope).

It is possible or even likely the immo should behave the same as the old Peugeot ones. The problem for me is that I am not very familiar with these. Maybe someone who is could answer a few questions on what is typical of these.

There are fault codes. If I unplug a sensor it will log an additional code for it but none of the codes will clear. Maybe normal for these to not clear codes if immobilised?
Everything scopes perfect, cam, crank, fuel pressure, fuel volume and pressure control, supplies and grounds etc but the ecu is not switching the injectors. What is usually immobilised on these, injectors or anything else?
Live data shows immo data as “not available” on DEC. Maybe DEC or maybe normal when immobilised or maybe DEC looking for CAN immo data from a BSI?
When on old Peugeots if the keypad had been unplugged did it then need the code input again after loss of system voltage?
