MIL Light on

G'day from Australia,

I'm new to this site. Please indulge me a little as I'm no mechanic and need some help.

The MIL light is on. I've read some good advice on this forum and did the on/off 3 times trick and the odometer display did the dashes and then said Done.

The light is still on, when I start the car is crackles a bit but it starts and drives ok (up to now anyway).

What next? Can I continue to drive it?

It's a 2008 model with only 38,000 Km's on odometer.

Looking forward to some sound advice from you specialists!

Thanks again.

MIL on? Find out why!

Your 2008 is OBD-II - as I recall, the "key bit" only works with OBD-I (for Jeep, that's 1991-1995.)

What you need is an OBD-II "code reader," it plugs into a port under the IP and accesses the computer directly. Fortunately, OBD-II is standardised, so you just need to find one that says "OBD-II/CAN Bus" on it. Up here, we can score them all day long (basic models) for under US$100 - I would imagine prices would be comparable down there at the locals. Units for professional mechanics can run well over US$2,000!

Another option is to get an interface to let your computer, tablet, or smartphone talk to your ECU. If you do it over Bluetooth (wireless,) you're looking for an "ELM327" adapter, if you're going to do it over wires, just look for an OBD-II to USB piece (then you plug your computer in to that.) Most of them come with basic applications, but I haven't used them. I downloaded Torque from the Google/Android shop (I use my tablet) and use that - wonderful!

I'm assuming you wouldn't have any trouble trying to find either over amazon.com.au or ebay.com.au, which would make the shipping easier (since that would be down in the Antipodes, instead of up here.)

OBD-II is effectively a worldwide/industrywide standard, so I don't expect you'd have much of a problem.

G'day!

the key trick does work on some OBDII rigs, but not sure about 2008.

do you have local auto parts stores there that will pull the code for you so you can search online for what might be causing it? if not, pay a mechanic to do it or get a cheap OBDII reader from ebay.

usually if the MIL light flashes while the vehicle is running then that means it's a severe problem and should not be driven. if it's not flashing then it could be minor or major, no way to tell without pulling the actual code.

Thanks for your input. The key trick did work and didn't register any codes and then gave the message 'done'.

My question is that the light is on but it hasn't given me any codes and wondered why not?

Thanks

it may be just doing a self-test on the gauges instead of reporting DTC codes, i'm not familiar with 2008. if you have the light then you have a code somewhere. it may also be a transmission controller generated code and perhaps those don't report with the key trick.

either way, i'd pay someone or purchase a reader and find out the code as soon as possible.
