The high beam circuits don’t use PWM anyway, so I think it might be a relay quality issue.Question - and maybe user error here - but i completed my front end conversion to all LEDs this weekend. High and low beams seem to be working fine, and i set both High and Low Beam LED = yes. However, i ran into two problems:
- I am attempting to trigger an LED light bar off the high beams. I could not get this to work previously because the PWM control of the high beams caused the relay to chatter. I assumed that finally setting the high beam LED = yes, this would disable PWM and the relay would no longer chatter...but that didn't work. It still behaves exactly the same as it did before. I let the truck sit with the key out for 5+ minutes after changing the config, is that enough time? I went back and checked and alphaOBD does indeed think that LED high beam is set to Yes. I am using LED high beams with an inline canbus module, so that fact that the high beams work fine could be a red herring.
- With park lamp DRL enabled, park lamp LED = yes, and LED turn signals = yes, i still get a bulb out message and my mirrors and dash hyperblink. Oddly, the actual LED turn signals work perfectly fine. These are switchback LEDs, so they're amber when in DRL mode and when the turn signal is activated, and white in running lamp mode (when the low beams are on). Again, functionally they are perfect, but i'm getting hyperblinking dash and mirror signals.
I know that my control via AlphaOBD is at least partially successful, because i enabled park lamp DRLs with no issue, and i was able to resolve flickering white switchback running lights (in the turn signal bulbs) by setting front park/marker lamp LED = yes. And, the settings are all as expected when i go back into AlphaODB. WOuld it be possible for Alphaobd to show the correct configuration but the BCM has not implemented it? Do i need more key cycles and/or to clear faults and/or take the truck out of park after applying settings and letting it sit?
Thanks for the help guys!
There seems to be a lot of the hyperflash/bulb out issues lately that varies from truck to truck. Usually it’s when there are switchbacks involved. Try cycling through the turn signals for a few minutes at a time, along with the hazards. You might just have to live with putting resistors in before the switchback modules.
