Little problem and some additional help
So, I own 156SW 1.9JTD 16V '05 (103kW) (192 A5.000) for 3 years now and I have a little problem with car, and wanted to fix it in next few days. And while fixing it wanted to add some stuff to it too.
First the main problem that I have is, I have error about cooler of the car. Namely 2nd speed is not working and I am afraid I will fry engine in summer times.
Did test the relay by the battery, it works and blower goes on higher speed. When testing it over OBD, it just runs 1st speed, 2nd not.
I found i AutoData that pin 69 on connector A (bigger one) should be the one that activates relay (pulls it to the mass), is this the right one?
Also, what are temperatures at which those two blower speeds are activated, I have a feeling that 1st speed activates pretty late... (I found it is approx 95 and 102'C but isn't that a bit to high?)
Now I found that on pin 58 (block A) and pin 41 (block B) it should have a coolant temperature readout (30'C - 3.2V, 60'C - 1.7V), what is normal working temperature of the car and its coolant temperature?
For some reason, I have a feeling that fuel and temperature gauge are not showing right value at all.
For fuel, somewhere at 1/3 on gauge is approx 1/2 of tank. And for temperature it is around 70'C (a bit too low), and then it jumps pretty fast over 90'C when heated a bit...
...now I bit of a additional help and questions?
Is it possible to change door locking module from 147 with window up/down function to 156? My car has key fob with 2 buttons (one for lock/unlock and second for trunk)?
How hard is it to equip car with TCS/ESP if it only has ABS module? (presumably also from other 156/147)
Can I retrofit a automatic wipers and what is needed to be changed in order for it? I presume that I'd need to get my hands on central rearview mirror with rain/dayligh sensors and handle that has auto besides standard functions, but is there anything else needed?
My car didn't come with front headlight washers, is there another pump needed for it? I noticed there is one spare connector in front bumper, is it for washer motor? Do I need to change the pump for it, or do I need only a Y junction to current tubing? Also is it possible to retrofit heater from 147 for washer fluid?
On pin 48 (block A) is a tacho readout (100Hz for 3000rpm), can this signal be used for digital tacho (HUD or something), and also what signal does a speedo at pin 27 (block A) gives, is it also impulse signal? Does anyone know for speedo what is proportion (km/h <> Hz)?
Last thing, is it needed to take off the wheel in order to change turn signal relay? It is by the handle of turn signals? Wanted to change all bulbs to LEDs and I do have problem with turn signals going high wire...
Thanks in advance
