I wonder if your TWICE is having issues. If it is, you will get weird flasher behavior and you may have OBD communication issues.
My 1999 9-3 Conv is having a bunch of electrical drama, flashers stay on (no OnStar), dome lights not coming on, air bag warning, intermittent blower issues, shift interlock not releasing.
I put my Tech II on but getting a “Cannot communicate with Dice”.
I pulled the com port and pins are good. I can’t get a standard reader to work as well.
Anyway, there are a ton of Dice units on eBay and getting another isn’t an issue.
Since eBay units have unknown or misrepresented past, how simple is a swap? I don’t want to brick my radio.
If Dice module is completely unknown, is it a simple process to marry it up? I’ve read some post saying you need the year and make to begin the marrying process, but if it’s unknown, do you just guess?
On a T5? I thought it would work (no marrying) ... but you'd need to configure if it didn't match.You need TECH2 for DICE marrying and configuring.
