Hi all... please could someone point to the location of the Check Control module for the bulbs? also, how to bypass it?
Will post diagrams, in short though, did a nice DRL project on my 2002 Omega 2.6L, the LEDs are 18W each and got a great DRL module from Amazon for $10 that auto-senses the engine On/Off, this worked great. But that DRL module can only support 12W LEDs so I added a relay for the LEDs and no issues there. Then, that relay needs to disconnect when the headlights are on (otherwise I really blind oncoming traffic), and so I added to that relay another one in series (Normally Closed) to turn it off when the right-side bulb gets 12V, or On.
My bad, that 2nd relay has no resistor/diode on its coil.
So.... started the car, DRLs turned on nicely, then I turn the headlights on, DRLs turned off as planned, great so far.
Then I turned the headlights off...
Live and learn. As it turns out unprotected relay coils can send back a spike of hundreds of low-current volts. The right bulb immediately fried. I wired back the right headlight (dipped beam) to regular wiring, replaced the bulb, double-checked the F31 (and others) but still no 12V on the bulb with headlight switch on. Possible the spike messed up that Check Control circuit, where even with no fuse attached I get 0.5V on the fuse's bulb end.
So, decided to take the Control Check Bulb module from my parts car, and here in OOF I found that it is either behind the glove box, or below the A pillar. Hours later... couldn't find the damn thing, on both cars.
So, please, where is the module? or how can it be bypassed (don't need it)? or is it just a matter of cutting the wires going from that CC module to the display unit?
Will add that I have the Haynes schematics, though it does NOT cover 2002 Omegas if there is a different pinouts for the display.
Thank you.
