Scan Gauges and warranty

Hi Tony

You can get the ScanGauge to reset warning messages/lights which is great if you are stuck somewhere on "limp home" mode. They can give you the reason/code why the engine warning light is on. But they don't turn off anything unless you ask them to!

Hi Tony,
I have my triton chipped and after a couple of times it has gone into limp mode because the sensor has detected a spike in the turbo. I use it to reset it so I'm not crawling back to the dealer to reset it. Money well spent, however I do not leave it plug in all the time.. Never take the word or a service manager with out getting it in writing.
Cheers Andy

Yes I think getting it in writing might be the difficult part.

Leigh W raised the point about whether or not the Sacangauge might "load up" (my paraphrase) the ECU in Thread 105890, Reply 524898.

I can see Lee's point. As I understand it from reading Scangauge documentation, to get the info it wants the Scangauge has to ask the ECU for information and the ECU has to reply. More tasks for the ECU, in addition to running the engine. So, depending on how the ECU prioritises its work, the Scangauge COULD be a detrimental processing load on the ECU. I suppose with an ECU that does not have sufficient overhead to absorb the extra load, it may stuff up (technical term) one or more of its primary tasks. (I am happy to stand corrected here.)

Try contacting the Aussie distributor and ask them if they have any info on this.

Cheers

Most as mentioned above leave their gauges connected all the time.

A dealers is connected to diagnose a problem.

You should compare apples with apples if intending to make judgements about suitability.

I had a scangauge connected to my Range Rover Sport for a year and it worked fine. Would only read high level codes that you had to look up and only clear basic stuff.

A year after I fitted it I had a lightning touchdown next to my car - 2 feet away and lets say the car had issues afterwards as the electronics went wild from the electromagnetic pulse from the lightning strike. After a while I disconnected the Scangauge and there was nothing wrong with the car electronics - it was the Scangauge causing the issues - things like no tacho, hazards on and off, doors locking and uplocking, car in limp mode, no auto changing of the gearbox etc.

The car's electronic systems were robust enough to handle the lightning strike but not the scangauge that was doing weird things to the car when it was plugged in.

I haven't bought another one but I would recommend them for the additional information it gives you and not the code reading and clearing ability. Unplug them though if you are parked near lightning.

Hi,
I have had a scangauge connected to my Pajero for a couple of years and have not seen any problems. They are designed to be connected all the time as it includes many real time monitors.

It would probably be a waste of money to buy it and not leave it connected.

I can’t remember if I had it connected when I last went to a dealer ad I have been getting my car serviced by other people.

How do I know if I have a plug for a Scan Gauge, and if I do have one where is it?

I have a Toyota 76 Wagon.
