Scanguage not initialising???

Mine used to be on a Terracan ( now a Challenger ) and mine does the same every now and then !!.....I even spied it once being "on", even though the car hadn't been running for hours ..

I only use mine now for readouts cause since putting a chip in the Challenger it has stuffed up the accuracy of the scangauge ( like I get 3 l/hk towing sometimes !!! )

Speak to the guys at Wooders Garage at Hornsby (02) 9477 4312 usually they are very helpful

Hi Ivan,
I have a scanguage 2 fitted a 2003 LC100 V8. It went well for about 12 months and while travelling it suddenly started to give strange readings and then went to gobbledygook, similar to $%#@6(*>"+ etc. Sometimes after restarting the vehicle after a pit stop it would come good for an hour or two and then go into gobbledygook again.

By the time I arrived home a few weeks later I was getting no display at all. I sent an email to Wooders (where I bought it from) and asked for advise, but my message must have went astray as I have never heard back from them. Which I found strange because they do provide good service.

After a few weeks I then contacted Scangauge in USA (service@linear-logic.com) and got a reply the next day. Unfortunately I didn't save the reply but it went something like this -

"Undo the four screws on the back and gently open the plastic case. Find the flat ribbon like lead with the (white??) connector which plugs into the mother board. Press the connector firmly but not roughly".

I did this, and everything went back to normal and worked fine. This lasted about 6 months and it started to play up again.

I repeated the instructions again and have not had a problem since (about 12months).

I think the problem first time around was that I was a bit tentative and did not press the connector firmly enough.

This may not be your problem but checking the connector may help.

Cheers

Occasionally i notice the scan guage has not turned on, maybe 1/2 dozen times in the past year. When on it all appears to work fine. Once I spied it all lit up late at night, i opened the door & then the light went out ...... no interior lights were on and door was closed ....... weird .....

Might try checking the plug is firmly in place both on Obi port and internal of the scan guage as suggested.
