My Multiscan ecu reader experience
So it turned up last night, and I got to work with downloading drivers and software-
Had to cut the Rubber protectors off the leads, because there was NO way they would fit the terminal (removed cover panel by right knee and theres a plug in there)
Went through the driver setup etc
Tried to do a "SCAN" and get
INVALID ISO CODE warning appear
So pressed "SIMULATE"
with yellow (abs) lead I got the following errors
P0704 Clutch switch
P1555 *description empty*
P0235 Boost pressure switch
When clicking CONNECT I get
" CONNECTION FAILED - No ECU response"
When i used the RED lead i get the following errors
P0704 Clutch signal
P1555 Accelerator/brake coherency
P0235 Supercharging pressure
So, I did a search on this forum, and found cleaning the map sensor usually gets rid of P0235
So, I set about doing this -
When I get chance, I will do a step by step - because this is very simple for anyone to do, as long as you know where to look, and all the info/pics I found, were not very clear
Also,....I came across what I THOUGHT it might be, but it had a sticker on the said that read - EGR
So, that was confusing -
I did a search on the part number, and it came up as MAP SENSOR
So, took it out, and Im amazed it has ever worked since I bought the car - It was SOOOOOO caked in gunk -
Used a toothbrush and cillit bang de-greaser to clean it up
Then refitted it
So, onto P0704 -
I did a search, and found the clutch pedal switch replacement will clear this - so, one has now been ordered, and waiting for arrival
Now this one has me head scratching a little-
I have read that the ecu detects the brake pedal being pressed while the accelerator is being pressed, and is confusing the ecu - bizarre, - but I also read, that adjusting the brake switch height, will cure this - (keep in mind, I changed the brake switch a month ago)
So, I have a question - HOW do you adjust brake switch height????
Also, before I finish -
When using mutiscan, ignition is at MAR, and I press the tab "Parameters"
and if I click one of the boxes, lets say engine temp, (same result with all of them) the numbers fluctuate wildly, - WHY IS THIS YOU STUPID THING ?????
That one was really getting on my nerves
edit - NONE of the "actuators" options worked-
