Help With Solus Pro

[autofella]

Hi there, I recently purchased a Solus Pro with the latest 9.4 software. I have used it to reset airbag lights and engine lights and diagnosing ABS faults with no connection or communication problems. The problem that I am having is that anytime I get a vehicle in with a fault in the catylst system or o2 circuit or air flow sensor circuit, I have no idea what I am looking for. For example, I have a Renault that is down in power and will not rev properly aswell as having a large flat spot when giving it a heavy rev at standstill. i plugged the Solus into it and the below code is coming up. I went into read data and the only data that I can see is one unit for the air mass meter (MAF) and it just sits still at 7.1. I have no idea about what any of the figures mean or how you are meant to get information to see what they should be. The same with o2 sensors, all this information is flashing at me but I do not know what it is meant to be. Can anyone help or steer me in a direction of understanding this ?

There is this fault number but according to Renault, it can mean any of these things :

1806 Air-mass sensor signal too high
1806 Air-mass sensor signal too low
1806 Air-mass sensor signal improbable
1806 Air-mass sensor Power supply not within range

Hi Autofella,

New products at first are always a mind blowing experience ,The problems are further amplified when a person has limited knowledge of the systems being analysed, which means one can soon become disheartend and give up , so what next?

Read the fault code(s)
Look up the general description of those codes(s)
Look at how those components actually work?
look at anything else that could affect or be affected by the operation of those component(s) being examined, then;

test those components as per manufacturer recommendations, and if a fault is not found with a component, don't change it, move on to the next one.

Take your current case;

The cat test, run the engine at a fast idle between 2500 - 3000 RPM for around 3 minutes when the engine is at normal operating temperature. using the Solus go into LIVE DATA and look up the lambda sensor which should be switching HIGH and LOW constantly. If two lambda sensors are fitted, the one after the CAT should not be switching when at normal operating temperature with a good cat.

If the front lambda is switching and the rear is switching, either the cat is not warm enough or is faulty.

MAF air flow meters do exactly what they say, they measure the mass of air flow passing over a heated wire inside the MAF unit. using the Solus in live data look up the MAF sensor and read the voltage at idle, then not violently but quickly accelerate the engine to between 3500 - 5000 RPM, or full throttle briefly, the voltage display should read over 4.5 Volts.

If I may say it sounds as though you need to do some research with books like the Fundamenals of motor vehicle science etc to get a good understanding of vehicle components and systems

It's all experience at the end of the day, keep it up you will get there eventually

Another great area to get some info on what the data should be reading is in Troubleshooter under Fast Track Data, Choose the particular PID you want and it will give you the info of what it should be and a live reading of what the vehicle is doing at that time.
Reading books is also a great idea to help you understand the fundamentals of the systems.
Good luck

Thanks so much for all that information. I definitly need to do some research and i will be the first to admit this. Is the book you mentioned readily available or is there other ones which you would recommend ?
I really want to get to grips with the scanner and its so flustrating that I am unable to use it properly.
Can I ask 2 questions :

1 - How do I print off using my pc the likes of heslth checks to give to customers ? I csn save an image of the screen but if its on scroll menu, it only prints off the one image that I am on ?

2 - How do I code new peaugeot 1.6 HDI injectors ? Do I take the coding from the old injector and code it into the new injector or do i use a fresh code and if so, from where ?

This area of the site will teach you how to use your SP much better! Some really great stuff in the videos!

Hi, the first question I normally transfer data to SSC then print from there, but you can print directly from the Solus pro with a printer, but have never done it.

Your second point with the injectors, take the codes directly from the injectors and use those. Sometimes manufacturers have a sticker on the engine with codes listed, but the problem there is that if someone had previously changed the injectors, you would then be using the wrong codes.

So do i keep the code from the old injector or use a code that comes with the brand new one ?

Hi Autofella,

If you purchase new injectors they will arrive with their own codes, so yes use the new codes.

Can anyone tell me why after removing an injector why after replacing, it would over fuel and make her very knocky ? All reading of other injectors show -0.12 or there abouts where as the one that was out now read 2.01 ? The only wires that were disconnected were the main injector wire. The new injector is correctly coded succesfully

try going into your trouble shooter option that should help you out.there are a lot of good training dites that you could visit also to try to learn some more.i would recomend flatrater.com,avivideo.com and have you thought about joining iatn?you could benifit from it greatly.jeff
