DIM CEL light not lighting up.

So I have a 2005 S60, the DIM is -210T model with the white plug. Today I disassembled it, thinking it has bulbs in the back, well it didn't. It seems like the symbols(on the right side when you power on the vehicle in POS II) are illuminated by individual LEDs, so now what?

Sounds like a feature, not a problem. Kidding. Do any of them work? Lamp check happens when you go to pos2 from no key in..

Most of them work, but no the Check Engine light, I also notice the fog lights (not sure if rear or front) symbol also does not illuminate, though my front ones do not work because of issues I have not taken care of yet. Everything else seems to work.

LED may have gone bad. If It's a Xemodex rebuild I bet they would fix the LED for you. Should be easy enough to solder

I am not anywhere near the American continent so yeah. But I can repair it myself so long as someone knows the exact LED SMD component? As long as it that is indeed the issue.

The DIM CEL wont light up on tests as ECM lights it up directly via its own invidiual wire not over CAN Bus nor DIM.

But it never does. I've had many critical engine errors but not once it lit up. I can even disconnect one injector and it would not light up.

You can use multimeter diode mode to check led is fine and then test it like how ECM should light it up via connector (if not then on PCB of DIM search broken connections) and then search and blame ECM or wiring between ECM and DIM for it not lighting up.
